About this episode

Voicemails and listener messages kick things off, including a detailed build-and-ownership rundown and a Toyota-focused prompt. The conversation then gets technical: small looseness at suspension link joints can snowball into shock loading, fretting, and fatigue failure, especially with rigid Heim setups. They also pivot to used-rig risk, “as-is” sales, and what drivetrain/suspension failures can look like. The rest of the episode turns into Facebook Marketplace pricing and negotiation tactics, plus glamping/camping banter and a few part-sourcing stories.

Technical Too Afraid to Ask
Term

preload

"For my experience, failures like what you described are often tied to a loss of preload on a fastener, leading to a joint slip, fretting, and eventually fatigue failure."

When you tighten a bolt, it squeezes the parts together. That squeeze force is called preload, and it helps keep the joint from shifting under driving loads.

Term

joint slip

"For my experience, failures like what you described are often tied to a loss of preload on a fastener, leading to a joint slip, fretting, and eventually fatigue failure."

Joint slip means the parts that are supposed to stay clamped together start to slide a little. Once that happens, the connection can wear out quickly.

Term

fretting

"For my experience, failures like what you described are often tied to a loss of preload on a fastener, leading to a joint slip, fretting, and eventually fatigue failure."

Fretting is when two metal surfaces rub against each other slightly. That small rubbing can grind the surfaces down and help cracks start.

Term

fatigue failure

"For my experience, failures like what you described are often tied to a loss of preload on a fastener, leading to a joint slip, fretting, and eventually fatigue failure."

Fatigue failure is when a part breaks after lots of repeated stress, like bending back and forth over time. It’s common when a joint isn’t tight and keeps getting loaded.

Term

shock load scenario

"In simple terms, the bolt stops acting like a clamp and starts acting like a pin that creates a shock load scenario, parts move, accelerate, and then slam into each other."

A shock load is a sudden jolt instead of a steady push. Those jolts can be much harder on parts than the original design expected.

Term

four link buggy

"Sure. Yeah. 100% with them so far on my four link buggy. If a bolt loosens up, say on an upper front link, I can feel slop in the entire"

A four-link buggy is an off-road suspension design that uses four metal arms to control how the wheels move. It helps the vehicle stay stable when the terrain is rough.

Part

upper front link

"If a bolt loosens up, say on an upper front link, I can feel slop in the entire"

An upper front link is one of the suspension arms on the front axle in a four-link setup. If its bolt loosens, the link can develop play (“slop”), which changes suspension geometry and can lead to accelerated wear or failure.

Term

Heim joints

"It's even more pronounced with true Heim joints, something like a hybrid Johnny joint is much more forgiving for a street driven rig."

Heim joints are metal joints used on off-road suspension links. They move freely, but because they don’t have rubber-like give, small looseness can create big stresses at the mounting points.

Term

Johnny joint

"It's even more pronounced with true Heim joints, something like a hybrid Johnny joint is much more forgiving for a street driven rig."

A Johnny joint is a suspension joint that’s designed to be a bit more forgiving than a fully metal joint. It can help smooth out bumps and reduce the harsh effects of small looseness.

Term

three link setup

"My guess is you had some form of looseness in the upper link on the three link that led to shock loading and fretting at the frame side bracket."

A three-link suspension uses three arms/links to control how the axle moves. If those joints or mounts get loose, the suspension can hit with extra force and start wearing out the mounting points quickly.

Term

shock loading

"My guess is you had some form of looseness in the upper link on the three link that led to shock loading and fretting at the frame side bracket."

Shock loading means the parts get hit with sudden heavy force. On rough terrain, looseness can turn normal movement into sharp impacts that stress the mounts and joints.

Term

locker

"Once things bound up in your front end, I don't think your locker had anything to do with what happened."

A locker is a device in the differential that helps both wheels on an axle drive together. They’re saying the problem wasn’t caused by that locking feature.

Term

diff

"Then when something in the diff, like a bearing started to fail, it could not handle the added stress."

“Diff” is the differential gear set that lets the wheels turn at different speeds when you’re turning. They’re saying a failing bearing in the diff could contribute to the overall stress and damage.

Term

backlash

"Even a few thousands of backlash play is a problem when you've got rigid joints with no bushing to absorb the load."

Backlash is the small amount of “slop” or free movement between parts. In a suspension, that slop can turn into extra stress because the joints don’t take up the movement.

Term

bushing

"Even a few thousands of backlash play is a problem when you've got rigid joints with no bushing to absorb the load."

A bushing is a soft insert that helps joints move smoothly and absorb shocks. Without bushings, the suspension parts take the full impact and wear faster.

Term

nut and bolt checks

"That's why a nut and bolt checks are so important on rock calling vehicles, especially if they're street driven vehicles."

It means checking that the bolts and nuts on the truck are still tight. Off-roading shakes things loose, so this helps prevent small problems from becoming major breakdowns.

Term

pinion and the bearing seizing up

"He caught the pinion and the bearing seizing up. Okay. He said, even if, you know, you know, something happens and something sees as like a bearing in your front diff, yeah, which is what happened."

The pinion is a gear inside the differential, and bearings help it spin. If the bearing seizes, it can lock up and cause major damage in the drivetrain.

Term

upper link

"but what caused the upper link to give out was not slop in a bolt or a fastener. Correct."

The upper link is a suspension arm that helps hold the axle in the right position. If it breaks, the truck’s handling and wheel alignment can go wrong fast.

Term

slop in a bolt or a fastener

"but what caused the upper link to give out was not slop in a bolt or a fastener. Correct. Correct."

“Slop” is extra looseness or wiggle in a connection. If bolts or suspension parts have that wiggle, they can wear out faster and fail sooner.

Concept

as-is

"if you're buying of a used rig, you're buying a used rig for the most part, you're buying as is, right?"

“As-is” means you’re buying it with whatever problems it already has. If something breaks later, the seller usually won’t be obligated to fix it.

Company

stellar built

"when you're a shop as large as stellar built, you're your name and your name's literally on the side of the vehicle in multiple spots on multiple spots and you're selling the vehicle as a $50,000 essentially race car ready to go."

They’re talking about a shop that builds and sells off-road rigs. The point is that a shop’s reputation and marketing can raise the stakes compared with a private seller.

Term

gazelle

"but I wouldn't put the gazelle or rooftop tent in. Yeah, but the gazelle you're on the ground."

“Gazelle” here sounds like a quick-to-set-up camping tent/awning that you use on the ground near your vehicle. They’re comparing it to a rooftop tent setup.

Term

rooftop tent

"but I wouldn't put the gazelle or rooftop tent in. Yeah, but the gazelle you're on the ground."

A rooftop tent is a tent that sits on top of your vehicle. People use them for camping because you sleep up off the ground.

Term

glamping

"If I can't stand up while I'm changing my clothes, I am not glamping. I'm sorry. So maybe the gazelle is glamping."

Glamping means camping, but with more comfort—like having nicer or more convenient gear. They’re joking about what counts as glamping based on how comfortable their setup is.

Term

toilet tent

"You could use your toilet tent. Yeah. Set up the toilet tent as your changing room. I've done that."

A toilet tent is a small privacy shelter used for bathroom needs while camping. They’re talking about using it as a changing room, too.

Topic

selling a 4x4 on Facebook Marketplace

"Hey, Jimmy and Tyler. It's Nick. Made man 925 gladiator on 22 driving the work. I'm listening to the podcast you guys did about, you know, selling Kermit. What's Kermit worth? ... I'm currently selling the Land Cruiser..."

They’re talking about selling a used off-road vehicle and figuring out a fair price. The caller mentions trying to come up with a number based on what they put into the truck.

Car

Toyota Land Cruiser

"What are his home for me? I'm currently selling the Land Cruiser and I'm selling it to a buddy. He's been trying to buy it for probably four or five years."

The Land Cruiser is a Toyota 4x4 that’s famous for being tough and good off-road. Here, they’re talking about selling one, and that usually means people care a lot about its condition and history.

Concept

resale value vs. build cost

"What is it worth now that I've used it? And I've abused some of these things. ... I think there's, to me, the easy answer is it's half of whatever you've spent. I think that's a fair starting point."

The hosts discuss how off-road modifications and hard use don’t always translate into resale value. They debate a “rule of thumb” that a vehicle might be worth about half of what was spent, then adjust up or down depending on condition and demand.

Car

Toyota RAV4

"What he did have is he had a RAV4. It's a 2020 with under 30,000 miles, all-wheel drive. It's the SSE. He said, I'll trade you straight up for this."

A Toyota RAV4 is a common everyday SUV. Here, it’s being used as the “normal commuter” car in a straight-up swap with a more off-road oriented vehicle.

Term

Blue Book

"And I tell you, Blue Book, that car was around 32 retail, you know, 30 private party."

“Blue Book” refers to vehicle pricing guides (most commonly Kelley Blue Book) that estimate a car’s market value based on factors like mileage, condition, and trim. The host uses it to estimate what the RAV4 might be worth in retail vs. private-party sales.

Concept

straight-up trade

"He said, I'll trade you straight up for this. ... So we just decided to do a swap. That way, I didn't really have to put a number on it."

A “straight-up trade” means swapping vehicles without agreeing on a separate cash price for either side. Here, it’s used to avoid the uncertainty of assigning a precise dollar value to a heavily used off-road truck.

Car

Jeep Gladiator

"And I know I have way more than that into my Gladiator and my Tacoma, but it's hard to see and hard to sell when you have that much into these."

The Jeep Gladiator is a midsize pickup built on Jeep’s off-road DNA, combining truck utility with trail-capable hardware. The hosts bring it up as another vehicle they’ve spent money on for wheeling, highlighting how off-road builds can become expensive to quantify and sell.

Car

Toyota Tacoma

"And I know I have way more than that into my Gladiator and my Tacoma, but it's hard to see and hard to sell when you have that much into these. So good luck with the fail of Kermit."

The Toyota Tacoma is a midsize pickup known for strong aftermarket support and off-road capability. In this segment, it’s referenced as a wheeled truck that’s been rebuilt multiple times, illustrating how repeated off-road use and upgrades can drive costs up and complicate resale value.

Term

accessories

"he's starting it for like what accessories have you put on it and how do those accessories last and how do they last time, how much are they worth"

In an off-road context, “accessories” usually means aftermarket add-ons—like wheels/tires, bumpers, lighting, suspension components, or other upgrades—that can affect both function and resale value. The speaker is specifically interested in how long these accessories last and how much they’re worth over time.

Term

Excel spreadsheet

"I never put stuff down an Excel spreadsheet to figure out like what I've been spending on vehicles"

Excel is a spreadsheet program people use to track numbers. They’re saying they don’t want to add up everything they’ve spent because it would feel overwhelming.

Concept

retail value

"So just like it did Nick exactly. But I would guess all in all Kermit has in retail value of everything that's been done to him"

Retail value is basically the “what it could sell for” price. They’re using it to talk about whether their upgrades are worth enough money when selling.

Car

Jeep JK

"So I'm like, [1377.2s] up JKs with tons, coilovers, long arms, atlases for like 25 right now."

“Jeep JK” is a Wrangler generation that a lot of off-road people modify. The hosts are talking about how people add big suspension upgrades to these Jeeps before selling them.

Term

coilovers

"up JKs with tons, coilovers, long arms, atlases for like 25 right now."

Coilovers are upgraded suspension parts that help the truck or Jeep handle rough roads better. They can also change how high the vehicle sits.

Term

long arms

"up JKs with tons, coilovers, long arms, atlases for like 25 right now."

Long arms are a suspension upgrade that helps the wheels move more smoothly over bumps. It’s common on off-road trucks because it can improve traction on uneven ground.

Car

Toyota 4Runner

"there's no way I'm going to sell a 1994 4Runner for $40,000. So I'd rather just hold on to him."

A 1994 Toyota 4Runner is an older SUV that many people turn into off-road rigs. The hosts are saying it’s hard to sell one for a high price just because it has upgrades.

Concept

value of modifications when selling

"you know, if you put X on to your vehicle, how much is that worth when you sell the vehicle? ... he has a Jeep to sell, but he wants to take some of the parts off."

They’re talking about whether expensive upgrades actually make a car worth more when you sell it. Sometimes it’s smarter to sell the car stock and sell the parts separately.

Term

aftermarket-wise

"maybe bring it back to stock, sell the vehicle stock and then sell all the parts after market-wise."

Aftermarket parts are upgrades that aren’t made by the car’s original manufacturer. They’re talking about how much those upgraded parts might be worth to the next buyer.

Term

suspension and axles

"I've got, you know, [1440.2s] the, when I did the, the suspension and axles and the front frame section, [1445.3s] all in all, that was about 35, $37,000."

Suspension and axles are big parts that affect how the vehicle rides and how it moves. Off-road upgrades here can be expensive, and that cost doesn’t always show up in the sale price.

Term

California legal 34 swap

"not including the dual cases, the welders, the battery, the California legal 34 swap,"

A “swap” is an engine or drivetrain replacement, and “California legal” indicates the conversion was done to meet California emissions/inspection requirements. The “34 swap” is likely shorthand for a specific engine swap package, which matters because legality and emissions equipment can strongly affect cost and resale value.

Term

dual cases

"not including the dual cases, the welders, the battery, the California legal 34 swap,"

“Dual cases” means the vehicle has two transfer cases. That’s an off-road drivetrain upgrade that helps you crawl slowly with lots of control.

Term

smog ability

"the California legal 34 swap, [1463.1s] the smog ability of it. So it can be a road driven vehicle and not get hassled by anybody."

“Smog ability” means whether the vehicle can pass emissions testing. With big modifications, that can be the key factor in whether it’s legal to drive on public roads.

Term

lift kit

"take off the Bilstein kit and the lift kit and just get some factory upper control arms"

A lift kit raises the truck or SUV higher off the ground. People do it for bigger tires and more clearance on rough trails.

Brand

Bilstein

"take off the Bilstein kit and the lift kit and just get some factory upper control arms"

Bilstein makes suspension parts like shocks. If someone says they have a Bilstein kit, it usually means they installed a well-known upgrade.

Term

upper control arms

"and just get some factory upper control arms and put it back onto some stock wheels"

Upper control arms are parts that connect the suspension to the wheel. They help the wheel move correctly, especially when the vehicle is lifted.

Term

Toyota Axles

"Didn't he have Toyota Axles? Yeah, okay. Yeah. I don't know if I said this on air. Maybe I did, but it'll remind or some people"

An axle is the part that connects the wheels to the drivetrain. People talk about “Toyota axles” because Toyota 4x4 axles are common, tough, and have lots of upgrade parts available.

Term

20R intake with a carburetor

"Somebody When husband and I were going through the bins that I have of a bunch of Toyota spare parts, we found a 20R intake with a carburetor."

This is a Toyota engine part for an older style setup. The intake manifold routes air to the engine, and the carburetor is what mixes fuel with that air before it goes into the cylinders.

Topic

Facebook Marketplace shipping

"I posted it in a bunch of, like a, I posted it on Facebook marketplace and I posted it in a bunch of like four by four Toyota sales channels that I'm a part of and somebody messaged me instantly. Like I didn't get a lot of, I didn't get any action. And then all of a sudden I had one guy reach out and it was like,"

They’re talking about selling a used part online and whether they’ll ship it to the buyer.

Concept

wheel and tire swap for compatibility

"The Chevy six lug wheels, they came on the tires, the 40 inch tires that we now put on the Unimog [2041.3s] or Lord Farquaad. [2042.7s] Yeah. [2043.6s] A guy messaged me asking him to get the wheels"

They’re talking about buying/selling parts by making sure they fit the vehicle (like wheel bolt patterns). It also sounds like they negotiated a deal that wasn’t just cash.

Term

40 inch tires

"The Chevy six lug wheels, they came on the tires, the 40 inch tires that we now put on the Unimog"

“40-inch tires” are huge tires. They help the vehicle roll over obstacles, but they can also make the truck harder to drive and put more strain on parts.
