New Lift and Bad Mojo!

Picked up my 2006 Wrangler with 46k on her from the body shop thursday. It's the 2.4L SE and has 31's with a 2" BB at the time. Rode just right. All suspension in the front was replaced. I know DW but didn't have it. Sat I put on the RC 3.25" lift with Quick Disco's, Steering Stabalizer, Trans Drop and Rear Tracbar Relocation Bracket. All tight and it rode great up until today. It goes in to DW at about 43mph real bad...about crap myself. All is tight including Wheels(balanced). I haven't aligned it yet cause I know it needs to break in and sag but is this the problem? Steering wheel is straight.

Look for loose or damaged control arms and trackbars ect. Also get an alignment. I had the same problem it was a loose front trackbar.

Get the alignment asap. I had the same thing happen to me after installing the lift and the alignment made it all better!

Alignment check! I'll check the front tracbar but I never touched it when I did the lift.

My front trac bar was loose and the bolt had a 1/2" of play. Got it tight but still does it. Doing the alignment tommorow hope that fixes it.

Check front trackbar tightness,and draglink should run fairly parallel to the trackbar.Remember,on a stock tj,without adjustable control arms,alignment can be checked,but only toe can be adjusted.And toe can be set with a tape measure and a piece of chalk.They (aligment shops) cant correct caster or cambor,just take your money.

Often times the TB is the culprit for DW. Doesn't take much play at all either. I'm wondering if the TB being as loose as you have described, may have wollowed out the hole on the TB bracket. I would pull bolt attaching the TB to the axle, remove the TB from the bracket, and examine the holes to make sure that there is only enough room to slide the bolt in and no play in the bracket. Examine the bushing while the TB is out. If it's not that or the alignment, then I'd start diving in and checking bushings, rebalance tires, etc.

I just replaced the track bar bushing on mine with only 42,000 miles on it.

I had my shop down the street look at it. He did the trac bar but couldnt do the alignment till tommorow. I also noticed aside from a couple things not fixed from the body shop. My tie rod bar on the pass side where it attaches to the lower ball joint? is smashed with the boot completely torn and no signs of grease. What about that?

1 thing I did not do during installation on the 3.25" RC lift is drill a hole 3/4" over on the front trac bar bracket and move the trac bar. It looked centered so I didn't wanna mess with it. What about that?

i just finished doing that same lift. relocate the front track bar or get an adjustable track bar. i had to drive mine from a buddy's house without the track bar relocated and got death wobble at 44 mph. replaced/relocated front track bar and got an alignment... no mo DW. also make sure the steering stabilizer isn't wore out.

I got their new perf steering stabalizer and an alignment. I have gone over 50mph yet which before over 40mph any bump went into death wobble. I asked RC about the front trac bar and they said it's jus to align the front axle, as long as it's tight it should be fine. When traffic dies down I am gonna try for a better test drive.

Ok so the tightening of the front trac bac and alignment helped alot. Now bumps arent terrible but when I hit about 60mph and hit a got bump it went into DW but not half as bad as it did originally. Like I said any slight bump over 40mph was crazy. Maybe if I try to move the front trac bar over and re align?

Try toe at almost 0. Rigs are picky. My Jeep likes 1/8" toe in with 39s. My tow rig likes 1/16" toe OUT with 37s. Ever had DW in a Ford Super Duty with a 6" lift and 37s while towing a Jeep on a flatbed trailer at 70MPH? Now THAT is scary!

Have you installed a front adjustable trackbar? I had DW until I put an adjustable trackbar (either on the front of the back, it didn't matter) to match the front up with the rear.

I would think it was not the adjusting, but the new bushings in the track bar itself that got rid of the DW.

Yeah when my front trac bar was loose before I tightened it I noticed my bushing got torn up pretty good. I didn't have it this morning but I never got over 55mph. I want an adjustable front one but want to make it work for now. I did the rear trac bar relocating bracket with the lift. I wanted to try and get through without doing another alignment just until my springs could finish sagging.

I relocated the front trac bar, double checked the alignment, and replaced the trac bar bushing. Everything in the front is good and tight but Every once in a while over 60mph a good bump goes into DW. I got to track this thing down. I've heard something about tires mine have about 35%-40% tread but I wanted to try to make it til the end of summer and was gonna put bigger ones on. I'm also curious about the steering stabalizer from RC, I put the performace one on could that be an issue?

Steering stabilizer alone will not be the culprit. If there is an underlying problem an old (or I suppose crappy, not saying your current one is) stabilizer will not help anything. The first thing many people do is recommend a new one, but often they just mask the problem until it gets worn out, then you are right back where you started.

Learned this one the hard way. Bought my Jeep already lifted (1st mistake). Within months it had DW, bad. Took it to one place - balance, rotate tires. They recommended a new stabilizer. I chose to wait. Took it to another place where I had my tie rod replace (the old one was bent), got an alignment, and they also mentioned the stabilizer. Ok, fine, I'll replace it. So I did. It covered up the DW for about a month, after which the DW was right back. So I have no confidence in these mechanics anymore. I finally replaced my front track bar and got a new stabilizer, and have been free of DW for over a year now.
