Four Wheel Underground

Four Wheel Underground is a company that makes and sells off-road suspension parts. The hosts say you can buy specific pieces by themselves, not just an entire kit.

Term

all a cart

They’re saying you can buy parts individually, like choosing items one-by-one, instead of having to buy a whole package.

Part

upper frame bracket

A frame bracket is a metal mounting piece that bolts the suspension to the truck. The “upper” one is where the top part of the suspension attaches.

Term

integrated bump stop

A bump stop is a safety cushion for the suspension. If the suspension compresses too much, it hits the bump stop to stop the metal parts from slamming together.

Part

lower link bracket

This is the lower mounting point for the suspension links. It also mentions an integrated bump stop, which is like a built-in “hard stop” to prevent the suspension from bottoming out.

Part

cartridge joints

These are the “hinges” at the ends of suspension links. Cartridge joints are designed to handle off-road stress and can often be rebuilt or serviced.

Part

rebuildable Johnny joints

Johnny joints are special link joints that let the suspension move through bumps without fighting itself. If they’re rebuildable, you can refresh the wear parts instead of replacing the whole joint.

Term

offsets

In this context, “offsets” are adjustable or different-position joint/link components that change suspension geometry. That can be used to correct alignment, tune ride height, or set proper link angles for better articulation and control.

Part

hymes

Hymes are basically spherical joints used on suspension links. They help the suspension move freely as the wheels go up and down.

Part

Aluminum links

These are suspension links made from aluminum. Aluminum can be lighter than steel, which can help the suspension respond better over rough terrain.

Term

link suspension kit

A link suspension kit is an upgrade that uses link arms and joints to guide how the suspension moves. It’s meant to help the truck handle rough trails better.

Topic

on X off road

OnX Off Road is a navigation app for off-roading. They like it because it helps you find and follow trails.

Concept

trail revival program

This sounds like a program where people work together to restore and maintain off-road trails. The goal is to keep trails usable and in good shape.

Wrangler Rubicon
Car

Wrangler Rubicon

The Wrangler is an off-road SUV. It’s designed to handle rough trails and is popular with people who go off pavement. In the podcast, it’s mentioned in connection with working on a trail like the Rubicon.

Jeep CJ
Car

Jeep CJ

The Jeep CJ is an older Jeep model line that helped define the brand’s off-road reputation. It’s the kind of Jeep people picture when they think of the early, simple trail vehicles.

Term

metallic

“Metallic” means the paint has tiny shiny particles in it. That’s what makes the color look like it changes a bit in different light.

Term

four liter

“Four liter” means the engine is about 4.0 liters in size. Bigger engines can help the car pull more easily, especially off-road or when carrying a load.

1993 Jeep Wrangler
Car

1993 Jeep Wrangler

A 1993 Jeep Wrangler is an older Wrangler generation. The host is saying it was a basic 4x4 that he bought for real-life use, not luxury.

Term

bikini top

A bikini top is a small, minimal roof for an open-air Jeep. It doesn’t fully protect you from rain or wind, so you feel more of the weather.

Term

half doors

Half doors are doors that only cover the bottom part of the opening. They make the vehicle feel more open, but they don’t block wind and rain as well as full doors.

Term

wind vortex

A wind vortex is swirling wind. With an open Jeep setup, the wind can loop around and blow back toward you instead of just passing over the vehicle.

Term

fire roads

Fire roads are dirt or gravel roads used by firefighters to reach remote areas. People use them for off-road exploring because they’re rougher than regular pavement.

Term

mines

Here, “mines” means old mining sites you can drive around or explore. The ground can be rough and uneven, and there may be hazards from the old site.

Jeep Grand Cherokee
Car

Jeep Grand Cherokee

The Jeep Grand Cherokee is a mid-size SUV. It’s made to carry a family and still handle rough roads better than many regular cars. People talk about it a lot because it’s a popular used SUV choice.

Ford Windstar
Car

Ford Windstar

The Ford Windstar is a minivan. It’s the kind of vehicle people use to drive families around because it has lots of space. In the podcast, it’s mentioned as the wife’s daily vehicle while another car wasn’t being used much.

Honda Odyssey
Car

Honda Odyssey

The Honda Odyssey is a minivan. It’s made to carry people comfortably, especially families, with lots of space inside. The podcast mentions it as a replacement vehicle when the owner’s needs changed.

Term

galvanized body

Galvanized means the metal has a protective zinc coating. That helps the Jeep resist rust, which matters a lot on older vehicles.

Term

U joints

U joints are parts in the drivetrain that let the driveshaft bend when the suspension moves. If they wear out, the Jeep can vibrate or make noise and lose smooth power delivery.

Term

torque monster

A “torque monster” means the engine has a lot of pulling power. That helps the Jeep move slowly and steadily over rough terrain.

Term

22RE

The 22RE is a Toyota engine that off-road people often like because it’s tough and dependable. In this segment, it’s being compared to the Jeep’s engine for trail performance.

Term

valve cover gasket

The valve cover gasket is a rubber seal that keeps engine oil from leaking out where the valve cover bolts on. If it fails, oil can drip or seep onto the engine and create a mess (and sometimes smoke or smell).

Toyota Land Cruiser FJ 40
Car

Toyota Land Cruiser FJ 40

The Toyota Land Cruiser FJ 40 is a classic older Land Cruiser that off-road fans love. It’s known for being tough and simple, and it’s a big part of why the Land Cruiser name became legendary.

Topic

Jeep as the iconic off-road/military brand

They’re talking about why Jeep became the “go-to” brand people think of for off-roading and military vehicles. Even people who don’t know cars still recognize the Jeep name.

Concept

armies surplus Jeeps conquer the Rubicon

The Rubicon is a well-known tough off-road trail. The hosts are joking that old military-style Jeeps became legendary because they could handle trails like that.

Term

leaf spring suspension

Leaf springs are a simple, tough suspension setup that uses layered metal strips. They flex to absorb bumps, and they’re common on older off-road trucks and Jeeps.

Term

coil springs

Coil springs are round springs that squeeze when you hit bumps and then push back. Newer off-road vehicles often use them to better control how the wheels move over rough ground.

Term

four drive

“Four drive” here refers to engaging four-wheel drive for off-road traction. The speaker is describing a typical trail routine: switch into 4WD, then perform additional drivetrain steps to make the Jeep suitable for the specific trail conditions.

Term

unlock the hubs

Unlocking the hubs is about changing how the front wheels are connected to the drivetrain. After off-roading, unlocking them can make highway driving easier and reduce extra mechanical effort.

Term

disconnect your sway bar

A sway bar helps keep the vehicle from leaning too much in turns. On rough trails, disconnecting it lets the wheels move more independently so the tires can stay on the ground better.

Part

track bar

The track bar helps keep the axle centered and from shifting side-to-side. Locking it down is a way to make the Jeep track straighter and feel more stable when you’re driving off-road.

Concept

trailers are for boats

They’re joking about “trailer queens,” meaning off-road vehicles that mostly get hauled around instead of being driven a lot. It’s a vibe about how people treat their rigs—use them hard vs keep them pristine.

Concept

axle

They’re talking about the axle parts that help send power to the wheels. Off-road conditions can stress those parts, so a good build helps prevent damage.

Concept

driveshaft spitting out

They mean the driveshaft can come loose when the suspension moves a lot off-road. A properly set up rig tries to prevent that so you don’t get stranded or break parts.

Concept

road worthy vs trail worthy

They’re talking about setting up a vehicle to do two different jobs: drive nicely on the road, but also handle rough off-road trails. The goal is to make one Jeep that can switch between those two modes.

Term

40s or 42s

“40s” and “42s” are shorthand for very large off-road tires. Bigger tires help you clear rocks and ruts, but they usually require other upgrades to fit and work correctly.

Term

portal

A “portal” setup is an off-road modification that effectively lifts the wheels higher using gearing near the hubs. That gives you more ground clearance to get over obstacles.

Term

front and rear sway bars

Sway bars help keep the vehicle from leaning too much when you turn. Off-road setups often adjust them so the suspension can move more freely over bumps and rocks.

Topic

Rubicon trail

The Rubicon Trail is a well-known off-road trail with tough obstacles. Off-roaders use it as a “test” to see how good a vehicle build really is.

Company

Dynatrack

Dynatrack is a company the hosts mention as a place to get aftermarket parts. It’s part of the ecosystem of shops that help people build Jeeps for road and trail use.

Term

bolt on

“Bolt on” means the part is designed to attach with bolts and basic tools. It usually doesn’t require cutting or welding to make it fit.

Term

rear locker

A “rear locker” helps both rear wheels work together. If one wheel starts slipping on dirt or rocks, the locker can keep power going to the other wheel too.

Term

open front

“Open front” means the front differential is not locked, so the front wheels can rotate at different speeds. That’s typically less traction on low-grip surfaces than a locked differential, but it can be easier to drive and more predictable on mixed terrain.

Term

BFG mud terrains

These are off-road tires made for mud. The tread is designed to grip and move through slippery, muddy ground better than regular tires.

Topic

trail evolution and adaptation

They’re talking about how people change their off-road builds over time as they learn more about what works on the trails.

Term

lock everything back up

They mean switching the truck back into a more “locked” mode after the trail section—so it behaves more predictably when you’re done wheeling.

Concept

shade tree mechanics

It means regular people who work on their own cars at home, not professional mechanics.

Term

torque wrench

A torque wrench tightens bolts to a specific setting, so you don’t overtighten or leave them too loose.

Term

gears

“Gears” here means the gearing in the axles. Changing it can help the truck crawl better at low speeds or drive more comfortably at higher speeds.

Term

lockers

Lockers are devices that make both wheels on an axle turn together. That helps when one wheel is slipping so the truck can keep moving.

Term

compressor

An off-road compressor is basically a pump for air. People use it to refill their tires after driving on lower tire pressure, and sometimes to power other air-powered gear.

Term

aftermarket

Aftermarket parts are made by companies other than the car maker. Off-roaders use them to upgrade or customize their trucks and Jeeps with gear that fits their needs.

Term

brackets

In this context, brackets are custom mounting hardware used to secure an air compressor under the hood or in another location. Proper brackets matter because the compressor must stay rigid and protected during vibration and impacts off-road.

Jeep YJ
Car

Jeep YJ

The Jeep YJ is an older Wrangler model that a lot of people customize for off-roading. Here, the point is that it may not have as many ready-made parts, so you sometimes have to build your own mounting bracket.

Term

airs up my tires

“Airing up” is just putting air back into your tires after you drove off-road with lower pressure. It helps the tires handle normally again once you’re done.

Term

ARB

ARB is a brand name people use for air-powered traction gear. It can lock the wheels together using compressed air so you get more grip when trails get slippery.

Concept

off-road capable

“Off-road capable” means a vehicle has the hardware and setup to handle rough terrain—typically things like higher ground clearance, appropriate tires, and drivetrain features that can maintain traction. The host’s point is that it’s become easier to modify regular vehicles into something that can reach remote places.

Toyota Prius
Car

Toyota Prius

The Toyota Prius is usually thought of as a regular city car. The host is using it as an example of something that doesn’t seem built for remote trails.

Brand

Tesla

Tesla makes electric cars. The point here is that people are talking about off-roading even with cars that usually aren’t set up for trails.

Subaru Outback
Car

Subaru Outback

The Subaru Outback is a car that’s popular for bad weather and rough roads because it has all-wheel drive. It’s not a dedicated rock-crawling 4x4, but it can handle more than a typical car.

Term

35s

“35s” means tires that are about 35 inches tall. Bigger tires can help a truck go over rough stuff, but they usually need a lift and other setup so they fit correctly.

Term

lift

A lift means raising the truck’s suspension so it sits higher off the ground. That helps it clear bigger obstacles and tires, but it can also require other changes to work well.

Term

ground clearance

Ground clearance is the distance between the lowest part of the vehicle and the ground. When off-roading, more ground clearance helps prevent the undercarriage from hitting rocks or ruts, which is why lift and tire size are discussed together.

Term

ditch lights

Ditch lights are extra lights you add low on the truck or Jeep. They shine on the ground near the wheels so you can spot hazards off-road that regular headlights don’t reach well.

Term

rock lights

Rock lights are small lights aimed at the ground near your tires. They can help you see what you’re driving over at night, and some kits can change colors.

Concept

King of the Hammers

King of the Hammers is a very tough off-road race. It’s known for nasty rocks and rough terrain, so the vehicles have to be built for extreme conditions.

Concept

Ultra4

Ultra4 is an off-road racing style/series for very tough terrain. The cars are built to handle rocks and rough desert driving without falling apart.

Concept

river crossing

A river crossing is when you drive through water on a trail. It’s risky because water can reduce grip and can get into parts you don’t want it to.

Concept

rock garden

A rock garden is a rough trail section covered in rocks. It’s hard because the car has to keep traction and handle bumps and dips at the same time.

Toyota Fj
Car

Toyota Fj

The Toyota FJ Cruiser is a small SUV made for off-road driving. It looks like a classic off-road vehicle and is meant to handle rough trails. The mention suggests a specific one was not in good shape.

Part

differentiels

A differential is a part that helps the wheels turn at different speeds, especially when you’re turning or driving over uneven ground. If both the front and rear differentials get damaged, the vehicle can lose a lot of its ability to move and steer normally.

Term

mechanical sympathy

It means driving in a way that’s kind to the truck. Instead of beating on it, you use smoother throttle and avoid stressing parts too hard when you’re stuck or climbing obstacles.

Concept

off-roading recovery

They’re describing how stuck vehicles get pulled out on trails. Sometimes the vehicle is already damaged, and trying to move it can make loud noises as parts fail further.

Term

winched

To “winch” a vehicle in off-roading means using a powered winch and cable/rope to pull it out of a difficult spot. It’s a common recovery method when traction is gone and you need controlled pulling force rather than dragging or spinning.

Term

strap

A recovery strap is a strong strap used to pull a stuck vehicle. It’s used during towing/recovery so the pull is controlled, but it still needs to be set up safely.

Term

ring and pinion

The ring and pinion are big gears inside the axle that help send power to the wheels. If they get damaged, the axle can start making loud bangs and may fail completely.

Toyota 4Runner
Car

Toyota 4Runner

The Toyota 4Runner is an SUV that’s popular for off-roading. They mention it as one of the Toyotas people drive to these events.

Toyota Tacoma
Car

Toyota Tacoma

The Toyota Tacoma is a pickup truck that many people use for off-roading. Here, they’re saying a lot of the event attendees drive Tacomas.

Concept

towing

Towing means pulling something behind your truck or SUV using a hitch. Off-road folks do it to get their rigs to the trail or event safely.

Ford F450
Car

Ford F450

The Ford F-450 is a big, heavy-duty truck. People use it for serious towing and tough driving, and here they’re talking about having comfort features in it too.

Term

automatic transmission

An automatic transmission shifts gears for you. In this conversation, they’re comparing it to a manual and talking about how it feels and holds up.

Term

granny gear

A granny gear is a very low gear that makes the truck move slowly and controllably. It’s useful for crawling over obstacles or steep, bumpy trails.

Term

overdrive

Overdrive is a gear that helps the engine spin slower when you’re driving faster. It can make highway driving quieter and usually more efficient.

Term

six speed transmission

A six-speed transmission has six forward gear ratios, giving the driver more options to keep the engine in its best RPM range. More gears can help balance off-road crawling (low gears) with on-road cruising (higher gears like overdrive).

Term

gasser diesel

They’re talking about two types of engines: gasoline versus diesel. Diesel engines usually feel stronger for pulling heavy loads.

Part

bank's kit

A Banks kit is an aftermarket upgrade for some diesel trucks. It’s meant to add power, but when you push a diesel harder, the exhaust can get hotter, so people often watch temperature gauges.

Term

EGT

EGT means exhaust gas temperature—how hot the engine’s exhaust is. When you tow uphill or pull heavy loads, watching EGT helps you avoid overheating the engine.

2017 F 350
Car

2017 F 350

This is a newer Ford F-350 diesel made for towing. The truck has computer controls that help manage power and heat so you can push it without damaging things.

Term

computer regulates me

The truck’s computer can limit how much power you get. It does that to keep the engine from running too hot or stressing components.

Term

weight limits

Weight limits are the maximum safe amounts your truck and trailer are allowed to carry. If you go over them, the truck can struggle and the trailer can become unstable.

Ford F150
Car

Ford F150

The Ford F-150 is a large pickup truck. It’s often used for towing trailers and hauling things. In the conversation, it’s brought up because it can tow what people need for trips and off-road setups.

Term

tow rig

Your tow rig is the vehicle you’re using to pull the trailer. It needs to be strong enough and set up correctly so the trailer doesn’t make the whole drive unsafe.

Term

trailer rated

A “rated” trailer has a maximum safe weight it’s built for. But you also have to make sure the truck (the tow rig) can handle pulling that weight safely.

Term

weight carrying capacity

This is the maximum safe amount of weight the trailer can handle. If you go over it, you risk damaging the trailer and making it unsafe to tow.

Term

two inch ball

The hitch ball is the part that the trailer connects to. The ball size has to match the trailer’s coupler so the connection is secure and the weight transfers correctly.

Term

weight ratings of your tires

Tires can only safely carry a certain amount of weight. If you tow too heavy for the tire ratings, the tires can overheat and fail.

Term

shank

The shank is the part of the hitch ball that goes through the hitch. If it’s too small, the hitch can be less strong even if the ball size looks right.

Term

cargo rating

A cargo rating is the maximum safe load for your trailer/towing setup. You have to make sure you’re not exceeding the smallest limit anywhere in the towing system.

Term

trailer tires

Trailer tires are made specifically for trailers, not for towing vehicles. They’re designed to handle the trailer’s weight and the way the tire gets stressed when the trailer turns and when it sits outside in the sun.

Term

weather checked

Weather checking means the rubber is getting old and cracking from sun and weather. If you see it on trailer tires, it’s a warning that the tire may be weakening and could fail.

Brand

Carlisle

Carlisle is a tire brand the speaker calls out as a good option for trailer tires. Carlisle is known in the trailer-tire market for tires aimed at durability under trailer loads and towing use.

Brand

Good year endurance trailer tire

They’re talking about Goodyear’s Endurance trailer tires. The idea is that this tire line is built to last longer on trailers that spend a lot of time sitting and being towed.

Term

flat spots

Flat spots are areas where a tire develops a temporary or permanent deformation after sitting in one position. Trailer tires often sit for long periods, and flat spots can contribute to vibration and uneven wear when you start towing again.

Term

side forces

Side forces are lateral loads acting on a tire during cornering, when the tire is pushed sideways relative to its direction of travel. Trailer tires can see especially high side forces in sharp turns because the trailer’s wheels follow a different path than the towing vehicle.

Concept

tire vibration leading to a blowout

The speaker describes a common failure progression: a developing vibration can indicate a tire problem such as damage, imbalance, or a developing separation. In the story, the vibration escalates until the tire forms a large bulge (“goose egg”) and is close to blowing.

Term

goose egg

A “goose egg” refers to a bulge on the tire sidewall caused by internal damage, such as a separation in the tire structure. That bulge is a serious warning sign because it often precedes a blowout.

Term

wheel bearings

Wheel bearings are small parts that help your wheels spin freely. If they wear out—especially when you tow or drive hard—they can get hot, start grinding, and eventually fail.

Term

back seal

The back seal is like a protective cover for the bearing. It helps keep grease where it belongs and keeps water and dirt out.

Term

races

Races are the smooth metal tracks inside the wheel hub that the bearing rides on. If those tracks get damaged, the bearing won’t last.

Term

repack your bearings

Repacking bearings means putting fresh grease into the wheel bearing. Grease keeps the parts from wearing out too fast.

Term

trailer brakes

Trailer brakes are brakes on the trailer, not just the truck. They help the whole setup stop safely, especially when the trailer is heavy.

Term

weight-distributing hitch

A weight-distributing hitch spreads the trailer’s weight more evenly onto the tow vehicle. That helps the truck handle better and can make stopping safer.

Term

trunnion bars

Trunnion bars are metal arms on a hitch that help move trailer weight around. That helps keep your truck’s front end from feeling too light while towing.

Term

tongue weight

Tongue weight is how much the trailer pushes down on the hitch ball. Getting it right helps your truck handle better and reduces wobble while towing.

Term

tail walking the dog

"Tail walking the dog" is a colloquial description of trailer sway—where the trailer oscillates side-to-side behind the tow vehicle. It’s often caused by improper weight balance (like tongue weight) or insufficient hitch setup, and it can get dangerous quickly.

Term

airbags

Airbags here are helper springs that use air pressure to support the truck. They can be adjusted so the truck doesn’t squat too much when towing.

Ford Cougar
Car

Ford Cougar

In this podcast moment, “Cougar” is mentioned as part of a joke. It isn’t really explained as a car being used or compared. So there’s not enough context here to describe it as a specific vehicle choice.

Term

anti sway bars

When you tow, the trailer can start to wobble side-to-side. Anti-sway bars add resistance to that wobble so the trailer tracks more steadily.

Term

sway problems

Sway problems are when your trailer starts rocking or weaving behind the truck. It can get worse quickly, so it’s something you want to prevent.

Term

gooseneck

A gooseneck trailer has a hitch that rises up from the trailer and connects to the truck via a ball mounted in the truck bed. Because the connection point is farther forward and the load sits more over/near the trailer axles, it often improves stability for heavy towing compared with simpler bumper-pull setups.

Term

bumper pull

Bumper pull is the common trailer style that hooks up at the back of the truck. It can be less stable than gooseneck when you’re towing very heavy loads.

Term

frame mounted hitch

A frame-mounted hitch is bolted to the truck’s main structure (the frame). That’s stronger than mounting it to the bumper, which helps when you tow heavy trailers.

Dodge Magnum
Car

Dodge Magnum

The Dodge Magnum is a wagon-style car, meaning it has a lot of cargo space like a station wagon. In the conversation, it’s mentioned because it can be set up with a hitch for towing. That makes it useful beyond just carrying passengers.

Dodge Ram
Car

Dodge Ram

A Dodge Ram is a big pickup truck. People buy them for towing and hauling, and this host says they really like theirs—especially the diesel engine.

Term

Cummins diesel engine

Cummins makes diesel engines. Diesel engines are often chosen for trucks because they pull hard and can handle heavy work.

Term

short bed

A short bed means the truck’s cargo area is shorter. If you’re adding a camper, that shorter space can make the setup harder and may force you to change how you hitch or mount things.

Term

long bed

A long bed is the longer version of a pickup’s cargo area. If you want to put a camper on the truck, a long bed typically makes the whole setup fit and balance better.

Brand

Lance 855S

Lance is a camper brand, and the Lance 855S is a specific model designed to fit both short-bed and long-bed truck applications. The host also mentions the roof being resealed, implying ongoing water-sealing maintenance for the camper.

Term

extended hitch

An extended hitch is a hitch setup that reaches farther back from the truck. It’s used when a camper sticks out, but it has to be strong enough because it increases the leverage on the truck.

Term

two inch receivers

A receiver hitch is the square opening on the truck where hitch accessories slide in. “Two-inch” refers to the common size of that opening, which matters for compatibility and secure mounting.

Term

super truss

A truss-style hitch extension uses strong metal framing. The idea is to make the extension stiffer so it can handle heavier loads without wobbling or bending.

Term

payload capacity

Payload capacity is the maximum weight the hitch setup is meant to handle. If you extend the hitch farther back, the forces on the truck can get bigger, so you need to stay within the rated limits.

Term

trailer hitches

A trailer hitch is the part on your truck that lets you hook up a trailer. It’s designed to handle the forces of towing.

Term

tie down systems

Tie-down systems are the straps and anchors that keep gear from sliding around. They help keep things secure while you drive.

Term

3 inch hitch

When people say “3 inch hitch,” they mean the hitch receiver opening size on the truck. It affects what towing parts can attach and how much load the setup is meant to handle.

Concept

double stacker trailer

A double stacker trailer is built to carry two loads stacked on top of each other. Because it’s taller and the weight is higher, it can handle differently and needs more care.

Term

trailer brake magnets

Trailer brake magnets are electromagnets inside an electric trailer brake system. When the brake controller sends current, the magnets generate force to activate the trailer’s braking mechanism at the wheels.

Term

brake controller gain

A brake controller’s gain is the adjustment that sets how much braking power the controller sends to the trailer brakes. Higher gain applies more current to the trailer’s brake magnets, while lower gain reduces it—so you can match the trailer’s weight and brake strength.

Term

smart brake controller

A smart brake controller automatically figures out how hard you’re braking and adjusts the trailer brakes for you. It helps keep braking balanced as conditions change.

Term

dumb brake controller

A basic brake controller doesn’t automatically adjust much—it mostly uses the setting you dial in. If your trailer load changes, you may need to change the setting too.

Concept

trailer brake adjustment for load (gain too low vs too high)

You have to set the trailer brakes differently depending on how heavy the trailer is. Too much brake can make the trailer wheels lock up; too little brake can make the trailer not slow down enough.

Term

trailer brake lock-up

If the trailer brakes are set too strong, the trailer wheels can stop turning and start sliding. That’s not ideal because it can make stopping less controlled.

Term

trailer sway

Trailer sway is when the trailer starts wobbling from side to side while you’re driving. It can happen after a bump or if the trailer isn’t balanced well.

Term

magnets on your trailer

Many trailers use electric brakes. The magnets are what get activated to squeeze the brakes and slow the trailer down.

Term

trailer lights

Trailer lights are the signals and brake lights on your trailer. If they act up, it’s often an electrical wiring/ground problem.

Term

Seven wire plug

A seven-wire plug is the standard trailer connector that carries power for different lights and signals. It also helps ensure the trailer has a proper electrical ground.

Term

Grease your ball

This means put grease on the hitch ball so the trailer coupler slides smoothly. It also helps protect against rust.

Term

dielectric grease

Dielectric grease is a protective gel you put on electrical connectors. It helps prevent water and corrosion so the connection keeps working.

Term

spare tire

Your spare tire is what you use if you get a flat. The important part is making sure it actually has air and is ready before you leave.

Term

right lug nut

Lug nuts are the bolts that hold your wheel on. Having the right tool means you can actually remove the wheel if you have a flat.

Term

tow vehicle

A tow vehicle is the car/truck that pulls the trailer. When you’re towing, it has to work harder to speed up and especially to stop safely.

Term

trailer speed

Trailer speed is just how fast the trailer is going while you’re towing. Since the trailer adds weight, you need to drive slower and leave more room to stop.

Term

tow haul mode

Tow/haul mode is a setting you turn on when you’re pulling a trailer. It helps the truck manage gears better so it’s easier to control speed and not strain the drivetrain.

Term

exhaust break

An exhaust brake helps slow the truck using the engine instead of just the brake pedal. It’s especially helpful when going downhill for long stretches.

Term

weights when you're loaded up

They’re talking about how heavy everything is once you’ve packed the truck and trailer. The heavier you are, the harder it is to tow safely.
