Road wonder

[cphill209]

As much as i hate to post this I have too. Last week we installed a 2.5 tera flex lift with new shocks, springs, rear track bar bracket, rear sway bar links. The problem is this at high speeds it wonders all over the road. First couple times i thought it was just the wind. I have read on other places other JK owners with the same size lift by different companies are having same problem. So A what did we do wrong? Or is it becasue i still have stock sterring stablizer shock?

I still love the ride of the lift and has a ton of FLEX, just not the road wondering. ANY IDEAS

I really doubt the ss is a problem, as far as wonder we didnt change anything/ lossen anything that would cause wonder, ie, ca's or steering parts(except geometry).
Springs and shocks are the only added items and being new I doubt they are the issue.
Now, with your new center of gravity and slight change to steering geometry may cause a little wonder, also remember your wheel base is a little shorter now and your alignment may be off a bit with the new springs and shocks.

I would suggest a front end alignment but check tire pressure first hopefully some more will post up.

Have you had an allignment since you've put in the lift? Any time you change the geometry of the vehicle, you should have the front alligned. Also, the steering stabilizer is really just a band-aid to an underlying problem. But if you plan to change it Old Man Emu is a good choice. My TJ wanders a bit on the highway, but I chalk it up to the size lift I have and the fact it's a jeep.

Hey Ghost,
I was typing my reply when you sent your reply. I'm in agreement with you, have it alligned and see if that fixes it.

No alignment yet, I could start there, I read on jeepforum 08 jk had same problem with same size lift and he did an alignment and it was dead on did not help the problem.

welcome to the world of a lifted jeep i don't thing it will ever handle like a sports car or even stock after you lift it i know my cj is all over the road at anything over 50 gets kinda scary

[cphill209]

Yeah I suspected some but not to the degree i have. MY TJ was never like that of course I had 33x12.50 and only a RE 2 inch budget lift on it. I never had it aligned either. I can deal with it. It the wife DD that Im worried about keeping her happy(another reason to start my other jeep build) lol.

Quote this was psoted on jeepforum

I have an RE 3.5" lift. When I first got it back from having the lift installed, it wandered a lot. It turned out that my rear axle was not centered (the RE kit had a rear track bar relocation bracket but the axle was still not centered properly). I ordered a Poly Performance adjustable rear track bar (very nice track bar and you can adjust it without removing either end) and centered the axle. It made a big difference and the Jeep did not wander nearly as much. It still wanders a bit but is significantly improved.

I recently added taller rear springs to compensate for all the weight I carry in the back. I noticed the wandering is again worse. The added height will have moved the axle a bit to the passenger's side so that is likely the cause.

I would personally recommend an adjustable track bar (I'm running without a relocation bracket myself) and carefully centering the rear axle as a possible cure for your problem.



Larry think this could be it or that solid spacer for the bolt we left out. accidentaly.

That spacer is so you dont crush the relocation bracket by over tightening that bolt or when torqueing to the correct ftlbs, I would prefer it being in there but doubt that it is your problem.

An Adjustable trac bar sounds like some help according to your post, but like the others say it's not stock anymore.

My best guess would be add adjustable trac-bars front and rear, ensure the axle is centered, have an allighnment done, and ensure tire pressure all around match
