I just replaced my leaf springs in my 2001 XJ. When I did this I also added an add a leaf for towing. I now have a vibrtion only when accelerating. I have read the my drive line angles are most likly off. I was wondering if any one else has done this and what you did to fix the problem. Thank you for your help.

 

youre at stock height and in the rear you just add a leaf for towing? your angles should be fine. it shouldnt have lifted your rear end up anymore than an inch or two. throw some weight in the rear or hook up a trailer and drive it and see if the vibrations stop.
