They blowing smoke and clueless? Is this expected with this kit and Ranchos?
Interesting, what is in spec? Have you had a chance to drive it to see how it feels? Make sure you let us know how it comes out thanks

The shocks wont change your caster. LCA correction brackets or adjustable LCA's will allow you to compensate for the extra height.

The dealer-stated Mopar "camber nut kit" is supposed to allow to LCA adjustment to adjust the camber. The camber is just a hair out of spec. I have the alignment printout. It won't take much to the camber within spec. Should I go with the dealer recommendation, LCA brackets or adjustable LCA'S?

My bigger question is the notion that I have not seen this camber issue noted in any of my reading here on the TF PLK.

Has anyone with a 2012 JKU Sport S installing this leveling kit has this issue?

You have me thinking maybe I will see if I can get mine on an alignment table to see where I am at. I know talking to AEV they said with the small amount of lift they did not recommend there geometery correction bracket.
Based on this diagram I have 1.75" lift in the front. What is yours?

I didn't measure before or after but it appears I got the same as most folks using this kit, roughly 2" in the front and an inch in the rear.

Attached are to picture of the alignment report after the lift was installed. One is prior to adjustments and the other is after. You can see the caster is just outside of acceptable range.

The last attachment is a better picture of the new stance.

The cammed bolts are probably the cheapest solution. Though I have heard that they can shift out of adjustment. If you go this way, mark the final bolt position to give a reference to check for shifting.

The more it is lifted the lower the caster angle becomes. The best way to correct it is by running adjustable lower control arms. Cam bolts are just a cheap fix. How does it drive? Yea it is less castor but it shouldn't feel much different,a little more sensitive but thats it.

The steering feels a bit jumpy after the TF PLK installation. To address the CASTER issue (I know I wrote camber before...sorry to confuse you guys)...

I called Teraflex about adjustable LCA's. Jacob at TF stated before you purchase anything, I should loosen all 8 control arm bolts (uppers and lowers, left and right sides) and bounce the jeep up and down several times. He suspects the caster reading is due to the dealership installing the PLK without loosening these bolts, thus putting the control arm bushings in a "pre-load" state when they installed the PLK. Buy loosening, bouncing the Jeep and re-tightening it'll put the caster within spec.

I'll give that a try over the weekend.

Yes the instructions say to do that. I did so maybe that does make a difference.

Do people find they get more lift out of the TL performance leveling kit than the spacer leveling kit?

I know they both state it's the same amount of lift but with the stiffer coils is there more than 2" in the front and 1.5" in the back?

no I got 1.75" in front and 1/2" in the back with the performance kit. kind of disappointed in the rear lift would have liked a full inch. I am ok with the front lift. I will say the ride is better tho.

UPDATE: I got the dreaded death wobble today going to work today...scared to crap out of me. First time I've ever had that happen...within a week of my TF Performance Leveling Kit being installed. Remember, following the kit install my caster is now negative and out of spec. I tried loosening all of the front control arm bolts, shaking the front end and re-tightening. That didn't resolve anything.

This afternoon, I took it back to the dealership to address the death wobble and spoke to the head mechanic. He stated negative caster will give you the death wobble. He also said while recommended cam bolt kit would fix the DW and the caster issue, if it were his Jeep he would install the adjustable lower control arms to address it.

Thoughts?

definitely want to address it and adj control arms would be the preferred method. Seems odd yours is off tho on such a low lift. what is your actual lift based on this diagram?

JADMT-
I just measured...post kit install, I got 20 3/4" (from the center of the shock bolt to where rubber bushing touches up top, and 11 3/4" from the top of the spring perch to edge of spring tower.

The Teraflex part number is #1351500, which is the correct performance leveling kit for my 2012 JKU Sport S.

You got a full 1/2" more then I did based on those measurements. I have the same kit and jku. one way you could go that would only cost $100 is to try the AEV geometry correction brackets. They are simple bolt on bracket.

Now I have to figure out why I got another 1/2" out of the same setup. Could the extra height coming from the Rancho 9000 shocks?

At this point, I want to correct it the best way possible. So I ordered the TF adjustable lower control arms this evening. This will definitely bring the caster into OEM spec and get rid of the DW. Don't want to see that again.

Reviewing old posts here I noticed that jmartinb's "before" camber was exactly the same as the "after" camber. I suspect it came out of spec from the factory, unless the OP knows of something that would have knocked it out after delivery.

I think I'd have a talk with the dealer about that, even though alignment is only warrantied for 12 months, and it looks like the alignment problem was identified at about 15 months.....

I don't believe there is any way shocks should give you lift.

Up Hill Bill - the two alignment readings are as follows. The "before" reading was taken immediately after the lift was installed. The "after" reading was a result of the realignment.

Jadmt - Unless the kit's front springs are incorrect from Northridge or installed incorrectly (they appear well seated on the mounts), I am at a loss as to why I am getting 1/2" more lift than normal, thus throwing the caster out enough to warrant additional components to provide the necessary caster correction.

Unless an answer is discovered, this will get resolved with the adjustable LCA's. It is $600 more than I wanted to spend for this project, leaves me with questions about my 15-month old vehicle and a bad taste resulting from the DW experience earlier today.

Just damn. Your experience is downright scarey. DW on a virtually new vehicle? It just has to be something to do with the lift install???

Every time I read something like this I'm more convinced my moding days are over, and I'm going to stay with the great ride I am getting from my stock suspension, at least until the warranty is out.....

I would loosen everything up and bounce the jeep up and down on both ends and then retorque to proper specs to see if that helps.

Correct

No 2 jeeps respond the same to a lift. He could have had softer coils.

Sorry I missed this thread

Do not install cam bolts. AEV correction brackets if you have enough hight or lca's

DW is almost 99% of the time track bar related. CHECK TORUE. It not a bad idea to loosen and shake like mentioned.

Any questions ask me

Edit: $600 for lca's. more like half that.
Or uppers can be used but shortened.

Yes. But, I would tell the dealer, who INSTALLED this lift, to do it.....

Doesn't your dealer warrant the work they do????

I'd be all over them to fix this, or remove it and refund ALL my money!

X2

This is why I don't trust dealerships.

OP do a steer test. Have somebody turn the wheel 9-3 back and forth.
Here's a vid I took. Look very close at the track bar and bushings for movement beyond normal bushing deflection. http://youtu.be/hb6mrtqw2Ws
Then look around at all TRE's. if you find something you have ammo to bring to the dealerfail .... I mean ship
