07 JK Death Wobble

I purchased my 07 Unlimited X this summer and have recently encountered the DW. I've put a lot of research into this subject and believe the holes drilled for the Trac Bar have worn and are the cause of my DW. I've removed the Trac Bar and placed the bolt back in, and the bolt slides at least 1/8-1/4 in. from side to side in the hole. y'all guys think this is my definitive issue? I've also read that using a 9/16 bolt is a better for the upper and lower Trac Bar attachments. Here is a picture of the drilled holes, should replacing the bolts alone be enough to solve my problem. Thank you for your help and Merry Christmas!

Looks to me like the bushing hole is larger than the bracket hole, so a larger bolt along will not take the slop out of the trackbar. I'd drill the bracket to match the bushing and use the appropriate bolt.

Does it take a good bump to induce the DW or is it at a certain speed? If it's a bump, this should fix your problem. If it's at a certain speed, a tire balance issue may be inducing the DW, which is exaggerated by the loose trackbar.

A bump at a speed between 60 and 65 will start it.

Ok then fixing the track bar slop should take care of it.

Thank you, I've gotten my tires balanced. And a front end alignment wasnt necessary when I took it to get checked. The previous owner had installed aftermarket suspension, but left the stock steering damper so I replaced that for more aesthetic purposes and a little function. But by no means expected that to fix my problem. Hopefully this will fix my problem. I will update with my results because I would love to help anyone dealing with this because I know it is frustrating.
