Thanks! Iíll take measurements tonight and see where Iím at. Hopefully itís not off since I havenít had issues prior to installing the steering.

I did just have 1 loose jam nut on the tie rod and 1 loose on the draglink. Cranked those back and will test drive to see if thatís all thatís causing it.

Tightening up the jam nuts did not solve the problem.

Re: Another death wobble thread

Did you check the bushings in your control arms? are the uppers still stock? they look like it in the pic. The uppers were the cause of a death wobble on one of my cherokee's

Sorry for the late response. Yesterday was a long one.

I have not checked but will ASAP.

My pitman arm has the slightest bit of play and makes a small clunk when I tap hard with my hand. Wonder if this might be the culprit. Just need to figure out what is causing the play.

Re: Another death wobble thread

When you say pitman arm, what do you mean; where the shaft enters the steering gear or the other end with the hole and TRE?

Either way, any slop can cause problems.

Seems to be where the shaft enters the steering gear. Still need to check the steering box bracket too. But the shaft definitely has a little play.

Re: Another death wobble thread

I just installed the same steering and ecountered the same issue. I had no death wobble before and now I can't go over 40mph. I haven't had a chance to check for play in my front end but am hoping to crawl under there this weekend. My oem steering had a stabilizer and my current setup does not. I installed the draglink above the pitman arm.

Thatís weird. Hopefully itís not just cavfabs setup. Your drag link/trackbar angles look really good too. Iím also running the draglink over the pitman arm.

Let me know if you find anything and Iíll keep you updated on my findings!

Re: Another death wobble thread

Iím completely stumped

Checked list
Ball joints
Wheel bearings
Rod ends / heims
Alignment
Wheel balance

Everything seems okay. My bushings seem okay by just looking at them.
Put a jack under the lowers and didnít see any movement with the weight of the vehicle on them.
My uppers are stock and the bushings look okay, my jeeps just over 100,000 miles so maybe time to replace those anyways.

If it wasn't for drilling out my pitman arm and knuckles i'd just reinstall the stock setup. I've never replaced the balljoints so i'm just going to start there since i should give them attention anyway. A buddy mentioned that I could have always had an issue and that my steering stabilizer may have been hiding it. So I went ahead and ordered cavfab's stabilizer mount as well. I'll have some time to look at it this weekend. I'll keep you posted.

Re: Another death wobble thread

There is a reason jeep put a stabilizer on these vehicles. Hitting bumps between 40 and 55 mph can start a oscillation that results in a death wobble. I know everyone says if everything is perfect u dont need a stabilizer but not all roads are smooth. Put a good fox stabilizer on and be done with it.
