jay.barnes Well, just got done replacing the track bar (as well as learned what over-torquing can do to a bolt - I swear I didn't feel the torque wrench pop).

I took it on one of western MA's famously unkempt highways and the ride seemed tighter, and I didn't feel any beginnings of a wobble. I'll have to check it again after I swap the hard top for the soft one (weight distribution on the Jeep - hard top vs. soft top, riding alone vs. riding with a passenger - seems to have had a pretty significant effect on DW).

Thanks again for all your advice!

Moog is a good brand. Just swap them out and see if that fixes it.

Sorry. Didn't see the video. I'm on my phone in class actually.... Required attendance for an easy class....

Anyway, so do you mean you bought another stock one to replace your current one? Do you have a lift?

PStov98TJ What replacement track bar did you buy? And any amount of movement in the track bar is not good. Replace that bolt with a Grade 8 bolt that gives a good tight fit. Sometimes the hole is wallowed out from the wobbling. Can't remember what I replaced mine with but it's something like a 70mmx10.5mm. But do not quote me on that.

idiot magnet While you are under there rock the Jeep back and forth and check that your control arms are tight, then check your tie rod ends, u joints, tire wear, grease all of the zerk fittings and check your drag link for any play. Unbalanced tires can cause DW as well.
Good luck and I hope you can resolve the DW.

Shelby427 Next time keep the camera still not moving with the steering, makes it hard to watch the track bar. But anywho, yep I believe Is saw it moving one time.

If it moves, you got a problem there. Either replace the bar or bushing, and make sure the bolt is tight. 55 foot pounds if I remember correctly.

And it looks like someone has been in there before. Usually the bolt on that end is a Torx head. PITA! Someone did you a favor if they used the correct hex head bolt.

Troubleshooting track bar to kill death wobble

Hi, all

This is my first post here, so I'll begin with a thanks to all those who have contributed to this forum over the past years - I, being less than mechanically inclined, have been able to keep my '06 TJ running well for several years, and over 120K miles, thanks to the content of this forum.

However, at this point, I'm battling the dreaded death wobble. After going through the sticky at the top of the forum, I think I've got it nailed down to the track bar (or, at least the bushing). Although, I'm not sure if there's an acceptable amount of play in the bushing, or too much.

I've taken a video of the track bar end while having the steering moved from side to side, and was wondering if I could get some input (I'll apologize in advance for the odd focus at times, but there is definitely movement in there):

Track bar play 2 - YouTube

I've already got a replacement track bar to put in, I just need to know if I should use it, or maybe return it.

Any suggestions would be welcome!

Thanks,

-Jay-
