Holy Track Bar Bushings Batman! Wobble & Bump Steer Solved for $10 & 2 Hours

I'm a novice wrencher to say the least. I can do most repairs if I follow a manual or writeup but I've always struggled with suspension. Half of that has to do with having the space and right tools to work with. But this weekend I was pleasantly surprised that $10 and 2 hours of work solved a problem that I have struggled with for almost 3 years.

Since I bought my TJ I've had a pretty serious steering / suspension problem. Always had a little wobble above 50mph (just knuckle whitening enough to take the wife's car when I highway travel for long distances was required) and bumpsteer that puts those rice burner drifters to shame.

Like an idiot, one by one I replaced nearly every suspension component. Some needed replacement, some I did for convenience because I was already under the jeep and some because I never had a firm understanding of how the suspension components worked together. Neither did the dealership for that matter who was convinced that my wobble / bumpsteer woes were a faulty steering box.

But after replacing a slightly leaking steering box on my own and having the problem persist, I dropped every single component to have a look at bushings. Low and behold, I found a well hidden crack, all the way through the track bar bushings.

So this weekend, for $10 in parts from quadratec:

And two hours of work following this writeup:
http://www.gibnet.us/JeepMods/trackbar.htm

My steering / wobble problems are completely gone. Granted, maybe there were some other factors at play that may have been addressed before, but never in my life have I had such a cheap part & easy install make such a world of difference. It's like I'm driving a brand new jeep.

Thought this might be a helpful post for anyone searching for information related to bump steer and death wobble.

My problem: Track Bar Bushings.

Visibly there was no play, it wasn't until I actually disconnected the track bar from the axle mount and saw the well hidden crack in the bushing that the problem presented itself.

Hope this helps someone! Let's just say I'm f*%#ing thrilled to have finally figured this problem out.

I have a Currie adjustable track bar and it used to get loose and cause the same problems you seem to have had. Another thing that happened is since there was movement in the track bar the bolt that hold it too the frame weekend and actually broke. Since then I have but anther bolt on top of the original bolt to keep it from loosening again.

I only get wobble from like 40-47mph... then it just a gets a tad jiggely at higher speeds. But from 40-47 like clock work, serious wobble. I haven't lifted mine yet so when I do, I'll be sure to inspect the track bar.

That's probably tire balance, my 33s aren't balanced perfect and sometimes I get a little wobble around 45. They are balanced with BBs so it only happen occasionally, most of the time it's nice and smooth.

I replaced my bushing last night and my shimmy is gone. I'm very happy about that!
