You might need an HD steering stabilizer

Not sure, I'm no lift expert, but if they mentioned something about camber angles it means that your wheels are not perpendicular to the road...

You need to get your pinion angle measured to see if you need adjustable control arms (if you havn't got them) So go to a mechanic that has a guage to see if thats off. I hope for your sake it's not, 'cos they are costly. Of course it could be the alignment place don't know what they are doing too, so go to a reputable machanic thats familiar with lifts & ask him. Also getting a HD trackbar, preferably adjustable, front & rear is a good thing.
You could msg' Jerry Bransford on here, tell him what you have had done & I am sure he wouldn't mind helping you with his expert advice.

Oh yeah' & I have a 4.5"lift with one steering Teraflex stabilizer, rides like a dream.

I'm telling ya, with a lift that high, you're going to need more than a basic lift.

Pinion angle needs dialed in like mentioned above. You'll need adjustable control arms. This will correct your caster too (why your jeep drives like crap)

You'll also need trackbars to recenter your axles. This also will help with handling.

The stock driveshafts also are going to fail early. You have time, but start saving for them.

Don't bother with a steering stabilizer yet. Those hide problems, not correct them.

I don't know your tire size, but 35" and over creates more upgrades, mainly to the axles. So in short, get some front lower, and rear upper adjustable control arms, and a rear and front trackbar ASAP. Tell the shop to give you as much caster as possible WITHOUT vibrations.

The lift screws everything up. It eats caster, creates a very steep driveshaft angle, and off-centers the axles. The stock arms can't adjust to the correct alignment and DS angles. That's why you want bigger, adjustable control arms. The track bars re-center the axles under the Jeep.

After all of that, consider a stabilizer. It's used to eliminate steering wheel shake from potholes or road bumps...not to make up for death wobble, poor alignment, or mis-aligned axles.

Shame on that shop for not telling you this upfront

I can't help but ask: Why such a big lift? Especially from Rough Country, which I've always heard is barely passable when it comes to performance parts.

All I've ever heard is that it takes a lot of effort to make a 4" lift work on a 2-door JK. I recall you asking about a number of different lifts, including smaller ones from better companies. Looking online now, it looks to me like a 4" TeraFlex lift with shocks is over $2400. Rough Country is $500. Doesn't that suggest . . . something?

That said, I'm sure it can be made to work and that there are folks here who can help. And down the line you may have an awesome Jeep. I just hope it doesn't get wildly pricey for you though.

Good luck.

I just lifted my JK 4 inches with cobbled parts and trackbar relocate brakets. I got extended front and rear links and discos and the thing is straight as an arrow. No adjustable arms or trackbars. I think you guys that are have problems arent unloading all the steering components and torquing them correctly. I made the extensions for my brake lines as well. Not sure what all the trouble is all the time with lifting these things other than paranoia and the whole unload/ load thing which must be over looked or not done properly. I did not put a stabilizer on either, just running stock. I wheeled the Jeep this weekend with no problems at all. AND the drive to where I went is 90 miles each way. I wish I had time and would do these lifts all day long installed for a lot less than what you are buying these expensive kits for and still having issues. All that adjustable this and that is alot for the regular person to do never mind understand. Proper alignment is an art and being in the business I see that very few shops can do it and do it right.

It varies between Jeeps. Generally they'll throw all the grease out the boots, so inspect them when u fuel up. After that, they'll vibrate. When that starts, they need addressed. If you continue, the vibrations get worse, then the joint fails and they bust. You don't want a DS busting at 40mph. They tend to spin around and slam into everything, tearing out lines, hitting tires, denting skids....it's not pretty.

Rest assured though...they don't just bust out of the blue. You get some warning. Correcting the pinion angle on stock shafts with control arms will buy you time, so get her drivable first, then wait.

I'm at 3" with stock shafts...no vibes yet after 15,000. My front spits grease but I re-grease every oil change. I think it rubbed on my trans skid and tore open that grease boot

Branden & John412: You guys realize that you're both in Pennsylvania right? John, don't you operate a shop that could presumably straighten this all out?

I'm at 3" and other than the lift I got a rear track bar. With the stock arms my pinion is good, but caster is just a hair out. It drives straight, and handles good. Little bumpsteer if I hit angled bumps, but it's not bad. Stock stabilizer too.

John...you Jeep drives good though. This one doesn't lol. Brackets are a cheaper alternative to trackbars, and they also work. So you did it correctly too. Just keep adding stuff till it works.

I promise though OP, those trackbars are a major reason it's driving bad. You don't by chance remember what your caster and toe are set at do you during the alignment? That'll tell the tale of pinion angle and handling.

Oh, John...how long have you driven on stock shafts without CA's? I'm curious. It'll give a better timeframe for OP than my 15,000 mile example, as you both are the same height

Also one brands 2.5" is another 4" kit. A true 4" needs a front adjustable trackbar and front lower adj. control arms.

Instead, just get a smaller lift. Unless you running crap like the deserts of Afghanistan, you don't need 4" for 35's. Hell I bought a Teraflex 2.5" for my 35's, cut off the pinch seam, added a rear trackbar, and called it a day. What kinda terrain you wheeling on?

Oh hell I'd just do that then. You can get a BB, cut the pinch seam, trim the fenders, add a rear trackbar bracket, and go. That's the cheapest.

Or get a 3" lift, cut your seam, rear trackbar, and that's it.

Best bang for the buck is do what I did. Teraflex 2.5" lift (got me like 3") cut the seam, rear trackbar. I'm a 2 door 07, daily driver, mud holes and fire trails. It even can handle some rocks without touching.

I get mild bump-steer due to not quite enough caster, but it handles good enough my girlfriend isn't scared to drive it, and she's well…a girl lol

I'm only at about 3000 miles at this point. I fully understand that my drive shafts will need replaced and I will be ordering them soon. The alignment issues on the other hand I dont see. I dont care what you do with this type of set up and those shafts your gonna need to replace them no matter what, especially if you flex a lot. This is my DD and I wheel it every weekend. If I was not comfortable or felt something wasn't correct I would fix it. I have the means to do it beyond the average person and yes Braden I may be able to help you depending on where you are at. I do not own a repair shop I own an auto parts store with plenty of access to repair facilities and one happens to have a ridiclous 4 wheel alignment machine and those guys know how to use it.

Thats an old picture actually but kinda the same.

And Chester county is about 2 hours from the area I am in. If you can ask around and find the best alignment place in your area that would help. If not PM me and I'll see if I can get you an appointment up here. Also let me know what you have done so far so I can give you an idea of anything we may need to get you straight, in more ways than one THats kinda stupid but its funny also

Well, you need to either get what's on there taken off or get it fixed. The current shop you're at didn't even tell you that you would have these problems so they're out. It's up to you, but I'd be driving my ass to John's shop. No question.

Were working on that. If it was aligned at a shop and this is happening it obviously was not done correctly It should have been an issue during test drive and addressed than. They should have said that something wasnt right and this is the reason for it. The kit he got has enough stuff in it that there should not be a issue that cant be easily fixed assuming there is not other stuff wrong.

Fantastic--I was beginning to worry that we were going to start hearing about smoking driveshafts and near accidents.
