CV Axle snapped @ 8k miles

Its absolutely true. Any mod (if can be proven to be the fault for the incurred damage) has the potential to void the warranty. It doesn't mean doing any mod voids all warranties; it means if the mod you did can be traced back as the source of the problem, warranty won't cover the damage. OP is a prime example; aftermarket suspension caused this issue; warranty isn't covering it because of it.

 

No, he’s technically correct. The truck is warrantied to function as it departed the factory not after whatever we slap on it. If your lift/tires/whatever stresses a component beyond designed limits and it fails that is not a warranty situation. It doesn’t negate the entire warranty, just components effected by modification - ie you lift the truck and your door falls off, door is still covered.

 

IEsurfer, believe what you want. There's a difference between add-ons and modifications. For instance, go ahead and increase the diameter size of tires/wheels, blow out the differential and try to get a manufacture to fix it under warranty.

 

Yes obviously but the guy insinuated they’ll deny your warranty for any mod lets say you put stock size all terrains they could deny your warranty saying the extra weight of the tires put excessive strain on the drivetrain and suspension

 

Say I bought a set of aftermarket wheels for a turd gen that's still under warranty. The wheel manufacturer clearly states that for my truck, I need longer-than-stock studs to safely run this set of wheels, but I say "fuck that" too much work. Too much cost. Two or three threads is good enough. I just want my truck to look tres awesome.

Then I'm driving along and there's a weird feeling on a turn. And then it gets worse on the next turn. And finally after not stopping to check, one of my front wheels comes off. Destroying the suspension. Brake components. And a little bit of body work, too.

This is Toyota's fault, right? And turd gens suck, right? Because reasons.

 

exactly why I bit the bullet and and paid the premium for a used gold certified 22 trd pro back in April. True, I actually signed the papers on the hood of a brand new 24 4x4 sport. No, I’m not a 4th gen hater …the 24 hybrids hadn’t come out yet and I wasn’t going to blow through another spring and summer without a 'road-runner'.

 

Replacing tires with the same factory specified stock tire size wouldn't really constitute a "modification." Upsize those tires, and thats a different story.

 

if you put larger tires on any gen it will put strain on your suspension and drivetrain in fact I highly recommend you 4th gen guys not to put 35s or larger as a few guys who have put 35s on their 4th gen’s overheated their transmission

also I acknowledge the fact that I have my truck lifted with 33s will shorten the life of my cv axles I’m not denying that however I’m pointing out the cv axles should have not exploded at 8k miles even with 45 inch tires and 4wd on by simply backing out of a parking spot maybe if he was doing donuts nonstop for an hour

 

$50k is $50k... Maybe be nice and put some JB Weld on it

 

you could argue that stock size 10 ply tires weigh 10 to 15 pounds more than stock so that’s an additional 50 plus pounds of added stress in a court of law and the the traction pattern caused too much resistance than the design tolerance of what the stock tire pattern for grip and traction allotted

 

Interestingly, 4th gen has two different types of inboard CV joints depending on trim. OP's Sport has the tulip type joint. OR or OR hybrid has been shown with the double-offset joint (circular housing) which has more travel and stronger at higher angles.

 

And how many 3rd gen trucks had to put an ECGS bushing in because the lift caused problems?

 

I like to talk a little shit here and there and bust some chops but in all seriousness I will say this, I know a Toyota engineer who works directly under Sheldon brown in Plano (chief engineer for 4th gen taco) he told me the machining debris for the tundra ttv6 is a lie and that when they did r&d for it up in Michigan they didn’t make the tolerances tight enough

he did tell me his concerns about the 4th gen while he didn’t reveal any “insider secrets” I don’t want too divulge too much not to get him in trouble but he did say they are delaying the 6th gen 4Runner which is supposed to be completely identical to the 4th gen taco due to issues from the taco they need to address and fix

 

Pictures of the front diff mounts? Did you install the diff drop brackets which are included even with Icon's most basic stage 1 kits?

 

Ohh, that's good info.

Interestingly enough every CV I've broken and seen broken wheeling has been the outer joints and not the tulip joints. I'll be curious to see what happens to the 4g front drivetrain with those new CVs when people start pushing them with a front locker and big tires.

 

My scenario has the same diameter, same offset, same width on the wheels. Swapped the stock tires over, too.
The only difference is that the flange is thicker. Is it Toyota's fault?

And, lets be straight on the OPs scenario: He wasn't just "backing out" of a parking spot.
Parked in sand. Claimed to be spinning rear wheels. Engaged 4WD. The video shows he cranked the wheel and went from low traction surface to max traction on the asphalt. The axle pops when the front end grips on the pavement. He was not whiskey-throttling it, but there was obviously a shit-ton of stress on the front end in that situation.

 

They would be more accurate in saying it's because of the mods.

I understand your frustration. I was wondering if you added the diff drop as recommended by ICON. If so, your beef is with them.

If not, live, learn, and move on. Best of luck, let us know how it plays out.

I will say this for Toyota - on my 2019, I blew out the stock OR shocks with larger wheels and tires on the truck - and they replaced them - twice. I also blew the engine wheeling on a steep incline with a passenger side tilt and they warranted that as well. At that point, the truck was on a full aftermarket suspension with new gears and lockers. Toyota never blinked.

 

And it has to be a YouTube influencer for extra measure!

 

If you really want to escalate a resolution name the dealer. Regardless of what Toyota corporate claims a dealer always has options. Are they claiming damage to the diff? $5k for the repair?

 

4th gen has new IFS geometry, so not everything we learned from the last two decades is applicable. For example, there may be more plunge travel demand from the axle shafts as the suspension cycles. As precedent, some 1st gen aftermarket CV axles had a slip joint in the axle shaft.
