Warranty Denied Due to Modifications

[ShadowsPapa]

So you added a 2” spring spacer to lift the front end up, that adds to the suspension travel and bounce wind-up, adding space before contact with the hydraulic bottom out pad catches the axle and stops it gently.

Doesn't increase travel - shifts the travel range.
It doesn't add space between the stop if they also added the spacers or other devices like Synergy says to do.
If you use synergy 2" springs, they say you need to add 2" of spacer so the bump stop travels the same distance before hitting.
So if he's done it all correctly, he's changed nothing at all as far as the amount of travel in total (just moved it) or the space before the bump stop hits.
No more "wind-up" because it's the same springs, compressing the exact same amount, and rebounding exactly the same amount. Spacers make it simple. They change nothing other than make the vehicle sit higher. Travel distance, spring compression and rebound, all the same.

I'm not sure I've seen any mojave owners buy them? The install in every other Jeep is the same, cut the tube and put them in. The mojave doesn't have a tube and the hole is bigger. Combine that with the fact there's no evidence that they're any better than the stock ones, I'm not sure why a mojave owner would bother.

Damn, I guess I have a lot to learn about my JTMX............ never paid real attention to those parts (and with luck, won't really need to?)

Those damn discussions on a...discussion forum! God forbid someone point out that mojave bump stops and the towers themselves are unique and make aftermarket bump stops harder to install. Should just let the OP or anyone else reading this thread go out and drop $800 to "upgrade" only to need a welder to install them. And after all that time and effort they find out the bumpstops behave just like the oem ones?

Why did you assume I was referring to you?

I'm well aware I come off as argumentative. In reality I just want people to be aware that the mojave towers aren't like all the other JTs and JLs. For mojave owners they are better off running stock bumpstops in my opinion but that is an opinion. The fact is no aftermarket hydraulic bumpstops are designed to mount in the mojave. Of course it's possible with some fabrication to run other bumpstops in a mojave, but I see no evidence that it would be worthwhile.

I think using an extended warranty they are more particular about mods, not sure, just thinking. I also think that particular mods make differences?

As said above worth a try at different dealer, don’t do lawyer bit will cost more than repair!! LOL

Go Jeep!!!

Hi All,

2021 Mojave owner here with a Mopar Maximum Care extended warranty. I was recently denied on a warranty claim on the hydraulic front jounce’s (read as bump stops) that the Mojave’s have. Both driver and passenger sides are leaking heavily at this point.

My Mojave has an AEV 2” spacer lift and was denied due to “modifications”. While I understand that the suspension is modified, the kit is designed to work around the factory shocks, springs, and bump stops without any interference. The kit does a good job of this. Also will note that I’ve had warranty work done previously with the same modifications installed, however, the repair was based around an axle failure.

What I’d like to know is if there is any sense in trying my luck at a different dealer for the same repair. I assume they will go through the same process of submitting to Stellantis for warranty coverage, but would like to understand if anyone has had luck switching dealers and getting approved on the second try.

Sorry to hear that. Every Jeep I have owned has been modified with lifts, including 3 with AEV, and I have never had a warranty claim denied. But I have not had a suspension related claim, either. I can see that being grounds to do it.

All valid points, but I’m sorry I wasn’t more clear on the suspension travel overall, that it’s true it won’t change overall, but re-index the area of travel like you mentioned. However all other parts but the spacers being unchanged? The spacers will leave more space between the bottom out stop and axle. Giving you more jounce for hard hits, but less rebound travel that’s limited either by stops designed in, or shock length or straps.

The kit includes 2" bump stop extensions and 2" shock extensions so everything functions exactly like stock just 2" taller. On a Mojave this is more critical as the shocks have internal bypasses and need to stay in the ride zone of the travel as they get really stiff in the last portion of the compression travel and also get stiff near full extension to avoid bottoming or topping out the suspension on hard hits or jumps. The kit didn't cause the bumpstops any extra work or wear period.

See Zach's post - he beat me to it. No, there's no more distance for the stops to travel before hitting. That distance is maintained. It's like the Synergy springs and lifts - you add 2" - they put in spacers to take 2" back out of the distance between the stop and the pad it hits - they space the thing up.. No change at all.

If you have an overland, like I used to have, and you install taller springs, you use these inside the front springs to space up so that front stop doesn't have any farther to travel to hit something -

2" spring, you use the minimum 2" stop spacer. 4" spring, you stack on more to get 4" of spacer. That means the stop literally travels the exact same distance before 'hitting" that it did without a lift.
Obviously, Mojave would be different - or would it?

I just want to throw it out there that I appreciate all the dialogue in this thread. It's been civil and educational.

Yes that all true. But I did state if all other parts have not been changed. Meaning especially the bump stops, that would especially interfere with the specific valving within Mojave shocks. The biggest issue will be with the driveshaft angles in the new range of travel, plus brake lines might be too short. The straight axles in the Gladiator and Wrangler make this easier without interfering with outer prop shafts like in independent suspension, that are shorter with more critical angle wear.

2" lift won't see any issues with lines or shafts.

One of the local offroad shops wrote an article about this very thing lately. Lays out some key points, including the fact that the burden of proof is on the dealership to prove your aftermarket parts caused the failure.

There is what the law says and there is what is actually being practiced. The FTC is not going to parachute lawyers in on one's behalf if a dealership just outright denies and does not want to offer proof but a speculation. One then has to sue on their dime in a federal civil court to enforce the Magnuson Moss Warrant Act. They play a who has more money game.

It sucks beyond all belief, but it’s true.
