Driveline vibration
I have a 2000 Jeep xj 4.0 that I just replaced leaf springs on .. It is stock height and has 200000 miles on it .. When I accelerate from 30 to 40 mph you can feel a distinct vibration from the rear of the vehicle .. I'm not sure if it is u joints or pinion bearings ... Any help is appreciated .. I'm not sure if u joints have ever been done on this xj i bought it about a year ago and only noticed this vibration after installing leaf springs

Sounds like your new parts changed the pinion angle, causing the vibration.
Maybe some tapered shims on the axle housing/spring mounts would help get the angle correct.
Theoretically, the pinion angle should be on the same plane as the transfer case, + or - a couple degrees...

Well I was thinking of overhauling the differential and replacing u joints soon anyways .. Do you think the vibration would go away after that ?
