Hi everyone I have been lurking around the forum awhile and now I could really use some advise. I have an 86 XJ that i put pro comp 4" lift coils on the front and 4" blocks on the rear. I drove it home after putting it all together in my friends garage and at 45 mph I hit a bump and the front end vibrated so bad I thought it was going to fall apart. My friend redrilled the bracket for the factory trac bar but that is all we moved I just got the rear shocks today there where none on the back when this happened and I have not alighned the front end yet. anyone have any idea what caused this and what I might look at to fix this problem. Thanks in advance for any help.
