When I got my 96 XJ, it already had a 3" Procomp lift on it that had the relocation bracket. For a while I couldnt find where a clunk noise was coming from, turns out the bracket had cracked and had some play in it.
I had the bracket replaced, but it came loose again (bolt on). The shop welded it back in. While it hasnt come loose or broke again, I do have bump steer slightly.
Eventually I'm going to have that crap taken out and put an adjustable trackbar in there so I can get the geometry back. It just feels cheesy having it in there.
