mopar 2in lift

[OHJeeper]

Wow, I have changed out LCAs on several Jeeps including the JT. If you do it with the Jeep on the wheels one at a time it is super simple and easy to bolt them in, just push the tire front or back to line up the second bolt hole.

THAT is the trick: do the LCA's first with tires still on the ground.

Not sure what I did to get my axle so far out of position, but before disconnecting the UCAs I was an inch short. I could not get the axle to budge. Broke a pry bar and smacked my forehead so hard on the frame that I was past the point of seeing stars ?

I also didn't have a strong enough ratchet strap to pull the axle. Bought one the next day (3300 lb version) in case I need to do that again. I'm sure it will come in handy.

I didn't have any issue with installing the LCA. Removes old springs, raise the axle a little until the bolts can be pull out by hand, without any binding.

Same here. I did the install the same way and I didn’t have any issues installing LCA.

I did read about others having trouble with the LCA’s. I think most of the issues were from individuals trying to install LCA’s with the front springs installed.

I had the 2” Mopar lift scheduled but ultimately cancelled & decided against it. The shop where I had my lift done at were removing those lifts weekly due to death wobble that Jeep could not seem to fix. I did my own research here on the forums & there were multiple threads that confirmed what they were telling me was indeed the case. I ended up going with the JKS JVenture 3 - 3.5” lift with the fox 2.0 performance shocks & Yeti steering brace as Trail Jeep’s had recommended. Hopefully Mopar have those issues resolved, but I didn’t want to take a chance. I believe I made the right choice.

Lift kits don't cause death wobble. Worn/bad/damaged suspension and steering components cause death wobble.

That's why there are multiple threads about the Mopar 2" lift having death wobble immediately after installation & that Jeep can't fix it after multiple tries, & that removing that new Mopar lift kit fixes the death wobble issue, but naw your right couldn't be it. They also have issues with the Universal Joint failing & the bushings falling out on new 2021 vehicles.

I know many people with the Mopar lift and don't have death wobble. Once again, to say the kit causes death wobble should mean that everyone with the Mopar lift should have death wobble. If the Mopar lift is the cause, what part of the lift causes death wobble? The main component of the kit is springs, control arms, shocks, and end links. Which one of those causes the death wobble? You have other components associated with death wobble. Like balljoints, track bar, bushings, etc. But, nah none of those could be it. If that were the case, we wouldn't need companies like Yeti, Synergy, or JKS. Because none of those parts cause death wobble. I mean.... do you really know some of the main causes of death wobble? Caster? The need for an adjustable track bar or control arms. Then what about the Jeeps with other lift kits with death wobble or with no lift and death wobble? Again, lift kits don't cause death wobble. Hahaha!

Well your apparently way smarter about 4x4s than Trail Jeeps. Like I told another guy look it up yourself it’s called google, many reports of it, where there’s smoke there’s fire. You have your ideas & I have mine, my intent was to help people not make an expensive mistake, we both have our own ideas, plus we all know that stock parts & lifts from Mopar are the absolute best, right.

Not disputing anyone's claims on either side of this debate. Just wanted to add that after installing my MOPAR kit + Teraflex levelers in front I have zero issues with wobble (It's the AC part number, not AB). I also installed a Yeti XD adjustable track bar after a couple weeks and no issues there, either.

On the other hand, my 2008 JK has death wobble with a non-MOPAR kit. I took it back to the factory front springs and it went away. Added 2.5" spacers to the front, and it came back. I think it's the angle of the factory track bar after adding the height and it's not able to "push back" enough against the side-to-side motion of the axle. I've seen some track-bar relocation kits that are not necessarily designed to correct the side-to-side measurement, but restore the track bar angle for this exact reason...

Nope. I'm not smarter than anybody at all. And I definitely don't know more than some people. But, what I do know is that while it is very easy to throw a comment out there like stock parts and mopar arent't the best, the truth is that there are Jeep owners with other brand lifts like JKS, teraflex, etc. with death wobble. What I do know is that when trail jeeps (or any rig) has death wobble, in order to fix it, the find the specific part that is bad. Lift kits are comprised of several parts. Which brings the same question. Which part of the lift kit caused the death wobble? Repair shops look for the damaged part. Lift kits are comprised of multiple components. When you work on vehicles for half of your life, or have friends that own shops and work on jeeps for a living, you get hands on learning as opposed to google learning.

And when you google complaints about parts, you only get reports of people with issues. Why would someone who's not having an issue complain? I guess, even though I have 100,000 miles on the Mopar lift, I should make a random complaint to make people reading google happy.

But, here's another question. If you feel that stock parts and lifts from mopar are crap, then why buy a Jeep? So, you're saying they have issues from factory that are crap and you bought crap? Ok. Hahaha

You're right! I have my ideas and you have yours. I got my ideas from busting knuckles and turning wrenches, not from google. So, I'm ok with that.

No harm or argument intended! You have a nice day and a blessed new year! Stay safe out there!

Yep. the adjustable works great for centering your axle and in some cases help with the angle. But, a track bar relocation kit is for that reason (somewhat). I've only had to help install one relocation kit on the rear. It kept the track bar just about right where it needed to be.

Question? After installing the 2.5" spacers, did you go with adjustable control arms?

 

[MrFahrenheit]

The problem is that everyone calls any small shimmy death wobble. There's a huge thread over on the JL forum about "death wobble" which is not in any way talking about real death wobble. Over the years, the term "death wobble" has been misconstrued as any unsteadiness in the steering wheel. Real death wobble is uncontrollable and you cannot continue driving. I've experienced it and I personally doubt the claim of anyone that says they've driven through (sped up) death wobble.

I do not doubt that people have had shimmies or steering wheel shakes at various speeds after installing the Mopar or any other kit, but to say that the Mopar kit induces true death wobble on a large amount of rigs is extremely hard to believe given the install base of the Mopar kit. Like @tysongladiator said, there really isn't a whole lot to the Mopar kit. Loose control arms could cause death wobble but that is an installer error versus a kit error.

On the JK, no. I bought it used with a RoughCounty lift and this is my daughter's daily driver. I never liked the springs that came with the kit, and there is a specific construction area on her way to school where she gets death wobble every morning unless she drives at 20-30 MPH (the speed limit in this section is 50). I drove it a couple of times and it's definitely wobble. I have another JK with similar lift height, but using stock sahara springs and some spacers and it exhibits zero wobble. My JT is the same.

I decided to ditch the RC springs and go with Moog OEM springs. Without the 2.5" spacers the wobble disappeared, but she hated the fact it was now stock "Eeew!" she said "it's, like, factory looking now"... So, I added the spacers to get back the lift but the wobble came back, although not as bad, making me think it's the track bar angle.

Her caster is just slightly out of range (maybe 1 degree) but so is my other JK so I have not gone there yet.

Are you thinking it's the caster, or were you just asking in general about whether I changed out the LCA's?

Agreed... DW has been overused in general. I had it once on the hwy at 80MPH when I hit a GIANT pothole and it scared the sh*t out of me. All the ABS/traction/stability lights came on, lots of "dings" and I thought I was headed into the ditch.

My daughter's is definitely DW. It will continue to shake until she (or I) hard brake to a complete stop. Not just a shimmy... but, at 50 MPH I would not call it "death" wobble. She even just calls it "the wobble" and she knows how to compensate for it.

I believe the track bar and drag link should ideally be at the same angle and close to the same length. I would imagine with that lift you would want adjustable control arms or geometry correction brackets (if they are made for a JK). Are you using the same tires when 'returning to stock' versus with the lift? On a JK I'd be suspect of the track bar bushing being worn out. Perhaps the extra angle or the being offset to one side after the lift with a non adjustable trackbar is enough to induce it with slightly worn out bushings.

Before with stock lift and 18" stock wheels/tires, and after with the 2" MOPAR lift and 35" Toyo's.

Mopar lift w/ stock 33s tires is fine, but i developed bump steer after added the 37s. Steering stablizer fixed it.
