About this episode

The hosts kick off with a mix of community talk and listener voicemails, then dive into practical build details. Four Wheel Underground’s shift to buying suspension parts “all a cart” comes up alongside link-suspension upgrades and aluminum links. A caller argues about mismatched axle lug patterns (Sterling vs 10.25) and what it takes to make wheels fit, then the conversation moves to axle strength, differential rebuilds, and backlash setup. Later, the show pivots to camping gear—swags vs rooftop tents—and how to choose based on wheeling or tow-rig use.

Technical Too Afraid to Ask

a la carte system

"What's really cool about what they're doing right now is they're kind of changing the way the business is set in the sense that you get to now buy things all a cart. Absolutely. So if you want the upper frame bracket, you can just buy that."

It means you can buy parts individually. Instead of having to get a full kit, you can pick just the specific pieces you want for your setup.

upper frame bracket

"So if you want the upper frame bracket, you can just buy that. Yeah. If you want the lower link bracket because it has the integrated bump stop and it's super stout and it looks really good too."

A bracket is a strong metal mount that bolts the suspension to the truck. The upper bracket is the part up on the frame that helps hold everything in the right position.

lower link bracket

"If you want the lower link bracket because it has the integrated bump stop and it's super stout and it looks really good too. You can get just those before you would have to buy the whole kit."

This is the mount where the lower suspension arms/links attach. If it has an integrated bump stop, it also helps prevent the suspension from bottoming out hard.

integrated bump stop

"If you want the lower link bracket because it has the integrated bump stop and it's super stout and it looks really good too. You can get just those before you would have to buy the whole kit."

A bump stop is like a safety cushion. It kicks in when the suspension gets near the end of its movement so things don’t slam together.

Johnny joints

"So now you can buy those all a cart from cartridge joints, rebuildable Johnny joints, hymes, offsets, all sorts of different ones."

Johnny joints are special suspension connection parts that let the suspension move more freely. They help the links stay working smoothly when the truck is flexing off-road.

hymes

"So now you can buy those all a cart from cartridge joints, rebuildable Johnny joints, hymes, offsets, all sorts of different ones."

Himes here likely means Heim joints—strong joint parts that let suspension links pivot smoothly. They’re often used on off-road setups because they can handle lots of movement.

offsets

"So now you can buy those all a cart from cartridge joints, rebuildable Johnny joints, hymes, offsets, all sorts of different ones."

Offsets are ways to shift where a suspension part mounts. That helps tune the suspension so it fits better and behaves the way you want when the truck flexes.

Aluminum links

"Do you know what else he brought in-house? Aluminum links. That's pretty rad. He found a way to source aluminum links so that there's no extra charge on the suspension kits."

These are the suspension arms/links made from aluminum. Aluminum can be lighter than steel, which can help the suspension react better over bumps.

Term

link suspension kit

"So if you want to move your Toyota from Lee Springs to a link suspension kit, check out four-wheel underground."

A link suspension kit is an off-road suspension upgrade that uses arms/links to guide the wheels. It’s designed to help the truck flex more and handle better on rough trails.

Sterling 1025

"Tyler, you are 100% wrong. If that rear end that you have is a Sterling 1025, it was the Lord's pattern. You sure you've already heard enough shit for this, but I haven't told you yet."

“Sterling 1025” is a specific heavy-truck rear axle. The point here is that its wheel/parts setup doesn’t match what’s on the front, so you may have fitment problems.

lug pattern

"That is the 8-on-6-5 rear end and your front end is a super duty front end, which is an 8-on-1 70 lug pattern. So at some point, somebody moved, changed, re-drilled, did whatever to make sure that your lug patterns match."

The lug pattern is how the wheel bolts are arranged. If the front and rear of a truck don’t use the same bolt layout, it’s harder to use the same wheels and replacement parts.

8-on-6-5

"That is the 8-on-6-5 rear end and your front end is a super duty front end, which is an 8-on-1 70 lug pattern. So at some point, somebody moved, changed, re-drilled, did whatever to make sure that your lug patterns match."

“8-on-6-5” describes how many wheel bolts there are and the size of the circle they sit on. It helps you know whether a wheel will fit the hub.

super duty front end

"That is the 8-on-6-5 rear end and your front end is a super duty front end, which is an 8-on-1 70 lug pattern. So at some point, somebody moved, changed, re-drilled, did whatever to make sure that your lug patterns match."

“Super Duty” here means a heavy-duty truck front axle/wheel setup. They’re comparing that front setup to the rear axle so you can see why the bolt patterns don’t match.

re-drilled

"So at some point, somebody moved, changed, re-drilled, did whatever to make sure that your lug patterns match. I personally would get rid of that 1025, find yourself another Sterling 1050."

Re-drilling is when someone drills new bolt holes so the wheel can fit. It usually means the truck has been modified, and that can make parts harder to find later.

Term

rear axle

"Next one was the rear axle under Fiona is a 10.25, not a Sterling 1050, which is correct."

The rear axle is the part that links the back wheels to the rest of the drivetrain. If you’re modifying an off-road truck, changing the rear axle can change strength and what upgrades fit.

Term

ring gear

"So I had it necessarily considered finding a 10.5 sterling and putting that in instead. ... Yeah, you have the 10.25 ring gear."

The ring gear is one of the main gears inside the rear differential. It works with another gear to transfer power to the wheels, and its size affects what axle setup you have.

eight on six and a half

"Because I did not realize that it's an eight on six and a half lug pattern. Mine is definitely an eight on 170 lug pattern right now."

That phrase is a specific wheel bolt pattern: 8 studs on a circle that measures 6.5 inches. It determines which wheels will bolt on correctly.

Term

eight on 170

"Mine is definitely an eight on 170 lug pattern right now. So somebody redrilled it and redid the wheel mount surface for the eight on 170 lug pattern"

“Eight on 170” describes a wheel bolt pattern: 8 studs on a 170 mm circle. If your axle is set up for a different pattern, your wheels won’t line up.

unit bearings

"I'd rather have the unit bearings the way Kermit set up. So I had it necessarily considered finding a 10.5 sterling and putting that in instead."

Unit bearings are sealed wheel bearings built into a single replaceable unit. That usually makes maintenance easier and keeps the wheel running smoothly.

link brackets

"we'd have to reset up the link brackets and the shock mounts, but if I get the 10.5 sterling, it wouldn't be shaved."

Link brackets are the mounting points where suspension links attach to the axle. If you change the axle, you may need to move or adjust these brackets so the suspension still lines up properly.

Term

shock mounts

"we'd have to reset up the link brackets and the shock mounts, but if I get the 10.5 sterling, it wouldn't be shaved."

Shock mounts are where the shocks bolt to the vehicle. If you change the axle, you may need to adjust the shock mounting points so the suspension works the way it should.

Term

shave kit

"Correct. That would be a dunder down side. I don't think I would take the time to do a shave kit on it."

A “shave kit” usually means trimming or modifying parts to make things fit with more clearance. People use it when the axle or wheel setup hits something.

crush sleeve

"It just needs to not have a crush sleeve on it. [662.9s] And I would rather have unit bearings, but I can live with spindles."

A crush sleeve is a small part that helps set the correct tightness for bearings in the axle. Because it gets deformed when tightened, mechanics typically replace it when rebuilding so the bearings stay properly adjusted.

Term

spindles

"And I would rather have unit bearings, but I can live with spindles. [666.9s] Yeah. I just have to carry around an extra spindle nut to get those spindles off."

A spindle is part of the axle end that holds the wheel bearing/hub in place. If you want to take the wheel assembly apart for service, you often need specific hardware like the spindle nut.

Term

spindle nut

"Yeah. I just have to carry around an extra spindle nut to get those spindles off. [670.8s] Right. And maybe you need to carry around the part that is drilled out."

A spindle nut is the nut that holds the axle end parts together. If you’re taking the spindle/hub apart to fix bearings, you may need the correct nut to put everything back safely.

axle shaft

"it's going to be an axle shaft or a third member, a third differential. [693.4s] Sure. The likelihood of breaking the wheel mount surface itself is super low."

An axle shaft is the part that sends power from the differential out to the wheel. If the axle is going to break, the shaft is one of the parts that can fail.

Term

third member

"it's going to be an axle shaft or a third member, a third differential. [693.4s] Sure. The likelihood of breaking the wheel mount surface itself is super low."

A third member is the removable chunk in the rear axle that holds the differential gears. It’s basically the “center” of the axle that you rebuild or replace if the gears are damaged.

Term

wheel mount surface

"The likelihood of breaking the wheel mount surface itself is super low. [700.6s] You're going to crack a wheel and have a lot of other destruction [703.6s] before I think you break one of those."

The wheel mount surface is the flat area where the wheel bolts on to the axle end. The point here is that it’s less likely to break than the internal parts.

Term

rear differential

"let me know because I do have to go through and rebuild the rear end, [716.2s] the rear differential and put a different locker in it and everything."

The rear differential is the gearbox inside the rear axle that lets the two rear wheels turn at different speeds. That’s important when you’re turning or driving over uneven ground.

Term

locker

"the rear differential and put a different locker in it and everything. [719.5s] So I'm going to be spending $1,500, $2,000 on this."

A locker is a type of differential that can “lock” both rear wheels together so they spin together. That helps when one wheel is slipping off-road, but it can feel different when driving on regular roads.

four to one transfer case

"They're Rubicon, Jeep Axel, you know, four to one transfer case for a JKU."

In a 4x4, the transfer case sends power to both the front and rear wheels. “4:1 low range” means you go slower but with more pulling power, which helps when climbing rocks or crawling through mud.

wheels just spin too much

"a big part. Not enough and the wheels just spin too much and you're just carrying around a bunch of extra dead weight."

Wheelspin is when your tires spin but don’t really grab the ground. It usually happens when the surface is slippery or when there isn’t enough traction for the power being sent to the wheels.

Term

dead weight

"Not enough and the wheels just spin too much and you're just carrying around a bunch of extra dead weight."

Dead weight is extra stuff that adds weight but doesn’t help you drive better. On trails, more weight can make it harder to get traction and move efficiently.

torque

"it produces a max of 383,562.5 pound feet of torque. Stay safe and later. Wow. That was amazing. That might be one of my favorite text messages we've ever gotten. How much torque 313 383,000 and 83,000 562.5."

Torque is the engine’s pulling power—the force that twists the drivetrain. More torque usually means it can pull harder, especially when you’re stuck in sand, mud, or towing heavy loads.

three-link bracket

"the other thing is a three-link bracket tearing off. I have welded up I don't know how many fucking track bar mounts and three-link mounts off of link suspensions on the trail like a lot."

A three-link suspension uses arms to hold the axle in the right place. The three-link bracket is the part that the arms attach to—if it rips off, the suspension can lose control and the axle can move unpredictably.

Part

track bar mounts

"the other thing is a three-link bracket tearing off. I have welded up I don't know how many fucking track bar mounts and three-link mounts off of link suspensions on the trail like a lot."

A track bar is a steering-stability link that helps keep the axle from shifting side-to-side. The mounts are the metal brackets where that link bolts or welds on—and if they’re not strong enough, they can rip off on rough trails.

JK's

"It's always track bar in JK's and it's always three-link brackets on Toyota's because they weld the sheet metal housings and then they tear apart."

“JK” is a nickname for a Jeep Wrangler generation. People mention it a lot in off-road suspension discussions because certain lift and link setups can stress the mounting points.

Term

plated the frame

"to like just spread the load out on the frame after I've plated the frame because I've seen so many tear out on the frame"

Plating the frame means adding extra metal reinforcement to the truck’s frame. It helps distribute the forces from suspension parts so the frame is less likely to rip or crack at the mounting holes.

gear guys

"and then gear guys finding a good gear guy is like impossible. My gear guy is like 83 years old and has bladder cancer now so I just bought all the tools."

“Gear guys” are the people who work on the drivetrain’s gear ratios inside the differentials. Changing or setting up those gears is specialized work, and doing it wrong can lead to problems later.

setting up my own gears

"My gear guy is like 83 years old and has bladder cancer now so I just bought all the tools. I'm going to start setting up my own gears even though they sound like from my calls"

They mean they’re going to do the differential gear work themselves. That involves careful measuring and setup so the gears mesh correctly and don’t wear out quickly.

ripped off of the axle

"showed them what happened to the three-link bracket on Fiona and why it fell off ripped off of the axle and I'm still waiting for this whole saga to"

This means the suspension part broke free from the axle. When that happens, the axle can shift and the truck’s handling can get unsafe fast.

gear set

"The gears. I really enjoy setting up gears. I think it's a fun little puzzle to solve... I just don't have the time to do gears... to get the proper pattern that you want."

A gear set is the set of gears that controls the “gearing” of the drivetrain. Swapping it changes how the truck feels—whether it pulls harder or runs quieter at highway speed. Setting it up correctly is important so the gears wear properly.

backlash

"at least a Toyota gear set with the caps, the bearing caps on there that you change the backlash by twisting the bearings rather than putting in shims."

Backlash is the tiny “slop” between gears when they’re meshing. Too much or too little can make the gears wear faster or sound bad. Gear builders measure and set it so the drivetrain works smoothly.

shims

"at least a Toyota gear set with the caps, the bearing caps on there that you change the backlash by twisting the bearings rather than putting in shims."

Shims are thin spacers used to make small adjustments. In gear work, they help position parts so the gears line up correctly. That’s how you get the right fit without having to replace major components.

case spreader

"You might need like a, what is that called? A pinchy grabby thing? No, the spreader, the case spreader to get the carrier bearing mounts spread in order to get the carrier in and out."

A case spreader is a tool that gently opens up the differential housing a little. That makes it easier to get the carrier in and out without forcing parts. It’s the kind of job-specific tool you use when the fit is tight.
