711:  Jimmy Hits the Sphere, Tyler Hits the Rubicon — Memorial Day Weekend Stories
Term

integrated bump stop

A bump stop is like a safety cushion for your suspension. If the suspension compresses too far on a trail, the bump stop helps prevent damage and makes the ride less harsh.

Term

Johnny joints

Johnny joints are heavy-duty joints used in suspension links. They’re made to survive off-road stress and still let the suspension move through bumps and twists.

Term

hymes

Hymes are strong joint parts used in suspension. They help the suspension links pivot as the wheels move, which is especially helpful off-road.

Term

offsets

Offsets are parts that move a mounting point slightly to change suspension geometry. Builders use them to get better alignment and clearance for off-road driving.

Term

Aluminum links

Aluminum links are suspension arms/links made from aluminum. They can be lighter than steel and resist rust better, which helps off-road setups last longer.

Term

link suspension kit

A link suspension kit is an upgrade that changes how the suspension controls the axle. Off-roaders use it to help the wheels move better over rocks and ruts while keeping the vehicle more stable.

Wrangler Rubicon
Car

Wrangler Rubicon

The Jeep Wrangler is a 4-wheel-drive SUV built for off-road trails. The episode mentions doing maintenance while using it on the Rubicon Trail. It also notes an “elite partnership,” which implies there’s special support or involvement related to the Wrangler.

Term

laser net

“Laser net” sounds like a tool that uses lasers to measure things very precisely. Off-road shops use tools like that to make sure parts fit and are made accurately.

Part

axles

Axles are the parts that send power from the drivetrain out to the wheels. Off-road axles have to be tough because they take a lot of shock and twisting.

Part

knuckles

Knuckles are parts that help connect the steering and suspension to the wheel. They’re important because they affect how the wheel turns and how strong the front end is under bumps.

Part

unit bearings

Unit bearings are integrated wheel-hub bearing assemblies that combine the hub and bearing into a single serviceable unit. They’re common in off-road axles because they can simplify maintenance and improve consistency under heavy loads.

Part

axel housings

Axle housings are the metal “shells” that hold the axle internals together. They protect the gears and shafts and help keep everything aligned when you hit rocks or ruts.

Ford Ranger
Car

Ford Ranger

The Ford Ranger is a pickup truck, meaning it has a cargo bed for hauling and gear. It’s designed to handle both normal roads and off-road driving. The podcast mentions it in connection with a “Light Ranger 500” sale or promotion.

Bugatti Divo
Car

Bugatti Divo

The Bugatti Divo is an extremely expensive, high-performance sports car. It’s made for fast driving and track-style performance. In the episode, it’s mentioned because of a related display or stand, not because it’s an off-road vehicle.

Term

tows

Here “tows” just means pulling a trailer or camper behind the truck. When you tow, the truck has to work harder, so towing ability is a big deal.

Ford F350
Car

Ford F350

The Ford F-350 is a heavy-duty truck that’s designed to pull trailers and campers. Here, the point is that it tows well even when you’re carrying a camper.

Term

fuel mileage

“Fuel mileage” means how far the vehicle can go on a gallon of fuel. They’re saying towing didn’t hurt their mileage as much as they expected.

Term

flange head

A flange head is a bolt head with a wider base. That wider base helps it hold tight and spread force, which matters when you’re mounting something near plastic covers.

Term

M8 by 125

“M8 by 125” tells you what size the bolt is and how its threads are spaced. Using the right thread pitch is key so the bolt screws in smoothly and securely.

Term

hex head

A hex head is the kind of bolt head that looks like a stop sign shape (six sides). You tighten it with a wrench or socket.

Term

Torx bit heads

Torx bit heads use a star-shaped socket in the bolt. You use a matching star-shaped tool, and it tends to grip better so the tool is less likely to slip.

Term

button head

A button head is a low, rounded bolt head. It’s used when you need the bolt to sit close to the surface so plastic trim or covers can fit correctly.

Term

AC system recharged

Recharging the AC system means topping up the refrigerant so the air conditioner can blow cold air again. If it keeps needing refrigerant, there may be a leak that should be checked.

Term

roof rack

A roof rack is the gear-carrying setup on the top of your vehicle. It often uses special mounts and fasteners, and this episode is about getting those mounts to fit under plastic roof pieces.

Ford Bronco
Car

Ford Bronco

The Ford Bronco is a 4-wheel-drive SUV made for off-road trails. The episode talks about an older Bronco showing up at an off-road gathering. That’s a sign it’s still used and recognized by people who drive off-road.

Term

air down

“Air down” means letting some air out of your tires before off-roading. It helps the tire grip better on loose surfaces because it can spread out more. But if you let too much air out, you can end up with problems and have to add air back.

Term

valve cores

The valve core is the little piece inside the tire’s air valve that controls how air flows. Some people remove it to let the tire deflate quickly when they’re airing down for trails. It’s quick, but it’s easy to take too much air out if you’re not watching.

Term

air compressor

An air compressor is a tool that pumps air back into your tires. Off-roaders bring one so they can fix tire pressure when they air down too much. It helps you get back to the right pressure for safer driving.

Term

PSI

PSI is how you measure how much air is in a tire. Higher PSI means the tire is stiffer; lower PSI lets it flex more on dirt and rocks.

Term

dial mechanical gauge

A dial mechanical gauge is a tire pressure meter with a needle. It’s usually most accurate in the middle of its scale, so if your tire pressure is near the top or bottom of the range, the reading can be off.

Term

airing down

Airing down means letting some air out of your tires for off-road. It helps the tire grip better on dirt and uneven ground, but you have to air back up later.

Term

zero to 60 gauge

If you plan to set tires around 30 PSI, using a gauge that goes up to 60 PSI helps because 30 is near the middle of the dial. Gauges are usually more accurate near the middle than near the ends.

Term

air up

“Air up” means putting air back into your tires after you’ve run them lower for off-roading. It’s important to get the pressure right before you drive normally again.

Term

mechanical gauges

A mechanical gauge is a pressure meter that uses real moving parts inside. If you push it way past its rated limit, those internal parts can get damaged, and the gauge may stop working correctly.

Term

over pressurize

Over-pressurizing is when pressure goes higher than a tool is meant to measure. For gauges, that can bend or break the internal parts, so the gauge can’t be trusted anymore.

Term

recalibrate

Recalibration is the process of adjusting a measurement device so its readings match a known correct reference. In the segment, the host argues that once a mechanical gauge is damaged by over-pressurizing, recalibration effectively requires rebuilding the internal spring/mechanism or replacing the gauge.

Term

digital sensors

Digital sensors turn pressure (or other measurements) into an electronic signal. That signal can then be shown on a digital gauge, usually with less reliance on fragile mechanical linkages.

Topic

digital gauges versus analog gauges

They compare digital gauges to analog gauges and explain what happens when the pressure goes too high. The takeaway is that their digital approach is meant to avoid the failure mode of damaged mechanical gauges.

Term

inflation and deflation gear

This is the tire-pressure setup used off-road—tools that let you add air or let air out. Gauges matter because you want to know exactly what pressure you’re running.

Term

tire

They’re talking about how much air is in the tires. Off-roaders change tire pressure because it affects traction and how the tire “squishes” over rocks and bumps.

Part

front coilovers

Coilovers are the suspension parts that help the wheels stay in contact with the ground. Changing the front ones can make the truck handle rocks and bumps much better.

Topic

Trahoorex

“Trahoorex” sounds like a specific off-road trip or event. They’re saying the suspension changes felt noticeably better during that outing.

Concept

rock crawling

Rock crawling is when you drive slowly over rocks and obstacles. It’s careful driving because the vehicle can get banged up if you push too hard.

Concept

shearing stuff off

They’re worried about breaking parts off the truck. On rough trails, if you hit something wrong or stress the drivetrain too much, you can snap or tear components.

Term

pinch point

A pinch point is a tight spot on the trail where your truck or Jeep can’t easily move around. If someone gets stuck there, it can be a big problem because other vehicles can’t get through.

Term

tie rod

A tie rod is a steering linkage rod that helps connect the steering to the wheels. If it’s damaged or bent, the wheels may not steer correctly—sometimes even getting stuck in a bad position.

Term

pitman arm

The pitman arm is a steering lever connected to the steering box. When you turn the wheel, it moves the linkage that turns the wheels—if it’s wrong, steering can fail or get stuck.

Term

drive shafts

Drive shafts are the rotating parts that send power from the drivetrain to the axles. If they’re damaged or not connected, the vehicle may not be able to drive normally.

Topic

dirty dozen

“Dirty dozen” is the name of a specific trail area where they camp and drive. It’s basically a named spot on the route.

Term

front wheels up on the ledge

That phrase means the truck’s front tires climb up onto a rock step. It’s a typical trail obstacle where the suspension has to flex to keep control.

Term

XO cage

An “XO cage” refers to an off-road roll-cage style built to protect occupants during impacts or rollovers. It’s typically a welded steel structure that ties into the truck’s frame/structure to add strength and safety on rough trails.

Toyota Tacoma
Car

Toyota Tacoma

The Toyota Tacoma is a popular off-road pickup truck. Here, they’re talking about a modified Tacoma with extra safety/strength gear for trail driving.

Term

solid axle

A solid axle connects both wheels with one strong axle. That can help the tires stay on the ground better when the trail gets bumpy or uneven.

Term

steering box

The steering box is the part that turns your steering wheel input into actual steering at the wheels. If it’s broken, you might be able to spin the steering wheel but the Jeep won’t turn the tires.

Term

rear axle

The rear axle is the part that helps the rear wheels turn and stay connected to the truck/Jeep. If it breaks, the rear wheels may not work correctly, and the vehicle often can’t safely drive out of the trail.

Term

drag link

The drag link is a steering rod that helps move steering motion from the steering system to the parts that actually turn the wheels. If it’s loose or damaged, steering can fail even if everything else looks connected.

Term

steering shaft

The steering shaft is the part that transfers steering movement from the steering wheel to the steering mechanism. If it doesn’t turn when it should, it can point to a broken connection inside the steering system.

Term

PSC big bore box

PSC makes steering parts for off-road vehicles. A “big bore” steering box is designed to help your steering feel stronger and more responsive, especially when you’re turning on rough terrain or with bigger tires.

Term

red head box

“Red head box” is an enthusiast nickname for a specific style/brand of Toyota steering gearbox used in off-road builds. The “red head” name comes from the appearance of the unit, and people swap these for improved steering feel and durability compared with stock boxes.

Term

Saginaw box

A Saginaw box is a type of steering gearbox that’s popular in the off-road world. People upgrade to it because it’s a proven design and there are lots of parts and options available.

Term

winch

A winch is like a heavy-duty power puller used to get a stuck vehicle out. It’s mounted to the truck, and if the mounting isn’t strong enough, the winch or bumper can get damaged during a hard recovery.

Topic

the Rubicon

“The Rubicon” is a well-known off-road trail that’s famous for being really tough. It’s the kind of place where vehicles can break parts like axles or steering when they hit hard obstacles.

Term

splines were sheared off

The axle has a connection with ridges (splines) that lock it to the rest of the drivetrain. If those ridges “shear off,” the connection breaks, and the axle can’t transfer power the way it should.

Term

carrier

The carrier is the internal housing in the rear axle that holds the gears. If a broken axle part gets stuck inside it, you can’t just swap the axle easily—you have to get the stuck piece out first.

Term

puddles

Puddles on a trail can make things slower and harder because the ground gets slippery. They can also make it easier to get stuck if the puddle is deeper than it looks.

Place

Loon

“Loon” here refers to Loon Lake, a common waypoint/area used by off-roaders on the Rubicon Trail. People often stage vehicles there and use it as a reference point for timing how long it takes to ride or drive sections.

Topic

Rubicon trail

The Rubicon Trail is a well-known off-road trail in California. It’s famous for being difficult—lots of rocks, steep spots, and muddy or wet areas.

Term

Dana sixties

“Dana sixties” means the vehicle has Dana 60 axles. People bring them up because they’re designed for stronger, tougher off-road use.

Term

straight pipe V eights

“Straight pipe” usually means the exhaust is set up to be louder, with less muffling. “V8” means the engine has eight cylinders arranged in a V shape.

a little two door JK

“JK” is the Jeep Wrangler generation they’re talking about. A two-door Wrangler is the shorter version, which usually helps it maneuver on tight trails and obstacles.

Term

shaft part

A “shaft part” usually refers to a cylindrical metal component that transmits motion or torque inside a drivetrain or suspension system. In off-road breakdowns, a damaged shaft can prevent the vehicle from moving correctly until the part is recovered and reinstalled.

Term

magnet

They needed a small metal part that was hard to reach, so they used a strong magnet to pick it up. It’s a quick way to grab metal pieces without taking everything apart.

Term

toolkits

A toolkit is just the set of tools you keep in your vehicle for fixing problems on the trail. The host is saying they built theirs to be useful when something breaks out on the trail.

Brand

Gearwrench

Gearwrench is a brand that makes mechanic tools. In this story, the host says they had a Gearwrench magnet tool that helped get the broken part out.

Topic

upper helipad

They’re talking about a couple of flat areas on the trail (called helipads) at different heights. They stop and hang out there while working their way around the rocks.

Topic

camping down at Buck

They’re talking about where they were hanging out for the weekend. It sets the scene for the off-road trip and the vehicle work that happened there.

Term

ready welder

A “ready welder” refers to having welding equipment on hand to perform quick repairs on-site. In off-road situations, people may weld brackets, mounts, or damaged metal parts to get a vehicle back on the trail.

Term

hooking batteries together

They’re connecting batteries so the system has more power. How you connect them matters a lot—wrong connections can be dangerous or break the vehicle’s electrical system.

Term

drain plug

A drain plug is a screw that seals the bottom of a component so the fluid inside doesn’t leak out. If it comes loose or falls out, the differential can lose its fluid and start wearing out fast.

Term

diff

“Diff” is the drivetrain part that helps the wheels turn at different speeds when you go around corners. If it’s leaking fluid or low on fluid, it can get damaged.

Term

carnage welder

A “carnage welder” is a portable welder people bring on off-road trips for emergency repairs. If something breaks, it lets you fix it on the trail instead of waiting for a tow.

Term

Pelican case

A Pelican case is a tough, hard case for protecting gear. It’s made to handle rough travel—like water, bumps, and dust—so your equipment stays working.

Term

wire feed

Wire feed means the welder automatically pushes welding wire into the weld. That helps you weld more consistently without manually feeding wire.

Topic

welding for trail repairs

They talk about bringing welding gear on off-road trips so you can fix broken parts right there. In this story, they weld a damaged drain plug to stop a leak.

Term

jumper cables

Jumper cables are cables you use to start a car with a dead battery by borrowing power from another battery. It’s a common roadside/off-road fix to get the vehicle going again.

Brand

more flight

“More Flight” sounds like the name of the gear brand they’re talking about. The guest recognizes it and mentions owning the gear in Australia.

Part

rear air locker

A rear air locker is a device that helps your truck get traction by locking the rear wheels together. It uses air pressure to make that happen. This helps when one wheel starts spinning and the other doesn’t have enough grip.

Part

solenoid

A solenoid is like an electrically controlled valve. It decides when air gets sent to the locker to lock or unlock the differential. If the air line near it leaks, the locker may not work right.

Term

airline

Here, an airline is just the air hose that carries the pressurized air to the locker controls. If it leaks, the system can’t build pressure, and the locker won’t work properly. Fixing small hose leaks is a common air-locker maintenance task.

Term

air lockers

An air locker is a 4x4 feature that can “lock” the two wheels on an axle together. That helps you keep moving when one wheel starts slipping. It uses compressed air to engage and disengage the lock.

Jeep Gladiator
