Have had a real bad shake in my rear end of my 06 Unlimited. I finally found my problem. It was a loose bolt. I tightened it up and the shake went away. It wasn't long till it started back. To make a long story short I keep tightening the bot and it keep getting loose again with normal driving. I got under it today to see why it keep getting loose and I noticed the PO welded it (and a very poor job at that). I don't know what the bracket is called but it looks liked may be missing a bolt. Can somebody help me out here and let me know what I need to do. Do I need to replace it, get a new bolt? Thanks for all the help in advance.
If the bracket is welded it wouldn't need a bolt but yes there is one missing. That does look like some crap weld. And x2 which bolt gets loose? The one through the track bar? You really gota torque it.

Is it welded solid? That bolt that is missing is what keeps the bracket from pivoting on the torx bolt. The track bar is pulling and pushing on the top of the bracket. Without that bottom bolt it just pivots on the torx bolt causing it to loosen. Even with a lock washer you might keep it from loosening but it will still pivot and the rear will eventually shimmy like crazy going down the road. That is probably why the po tried to weld it.
if everything has started to get "wollered out" locktite blue may help, Locktite red it only if you don't want to take it off without heat, and green will penetrate bolts already torqued if you dont want to undo them.
Ok so it put some blue locktite on the torx head screw and put a bolt and lock washer on the bottom where the bolt was missing. We'll see if that doesn't fix the problem. I won't be able to test it till tomorrow because I'm at work and won't get off till 800 in the AM.
