Trackbar help

Ive been having some major wobbeling at 40-45 mph. It comes and goes, but latley its becoming so bad, I dont want to drive it anymore. I have a 2" lift with a 1" spacer on top in the front. the alignment was just done, tires are new and balanced. (1 tire in the rear had the weight fall off, so I switched with the spare.) I ran a different set of tires and still had the wobble. I can watch the front tires wobble back and forth when driving. I took a pic of my trackbar where it bolts on top. It looks out of wack to me, but not too sure. Does this look right? Should I order a new one? (If thats the case, Im ordering a whole lift then.)

If you're talking about that it's not perfectly square to the mount, yours is exactly how it should be.

You could have a bent wheel, or the other end of the trackbar where it bolts to the axle could be too loose even if it feels tight by hand. For an '05 TJ, it should be tightened with a torque wrench to 45 ft-lbs.

Imperfectly balanced tires can cause this too. Some tire shops only balance tires to the "good enough" point which in the TJ's case, isn't good enough. They must be perfectly balanced... literally perfectly or your TJ can develop shimmys or the notorious Death Wobble which you really don't want to experience.

I'm kind of thinking bad unit bearings if your tires are just randomly wobbling when you drive at higher speeds.

Is it Death Wobble where you have to virtually stop before it clears or is it speed related?

Trac bar looks fine to me too.

I was thinking the same thing but then I noticed he has an '05 where bad front bearings on this new of a TJ would be a real surprise.

Yeah, I would hope so Jerry. Just for some odd reason doesn't sound like DW.

I dont want to say dw because it does smooth out at 50+ mph. Ive never had to stop because of it. It only wobbles at 40-45. There may be days where it doesnt do it at all. Also, if Im doing 65 on the highway, when I slow down, it doesnt wobble at all. Ive had this problem for about 6 months now and its driving me nuts. The rims are brand new and I dont think, (or hope) that 1 may be bent. Never slammed any potholes or anything. As for unit bearings, I really no nothing of what that means. I am not a mechanic and I dont claim to be one so if you could help me out, it would be much appreciated.

I also tried other wheels and had the same exact problem.

As already suggested above, go have your tires PERFECTLY balanced. No guarantee but it sure sounds like a tire or two has a balance problem. I've had tires fresh from being balanced cause a shimmy so I had to make a u-turn and make the tire shop rebalance them again. It's never taken more than twice, and my tire shop now knows to get mine right the first time. You might call around to see if any tire shops in your town have a "Road Force" tire balance machine which is what my 35" tires respond to best.

Ill see about getting the tires rebalanced first. I just dont want anything major to happen because of this. If that doesnt solve the problem, should I get a new trackbar?

No, just check it as was suggested in some detail above as well.

As far as unit bearing he is referring to the hub Assembly I think.A bad hub Assembly on an 05 is not that uncommon with the roads we have and the wider wheels/tires we run.I have replaced them on newer full size Dodge trucks quite often.The newest I recall only had a little over 26000 miles on it.
