Hi,
My XJ has developed a high speed vibration, that wasn't there before. At any speed above about 45, it will vibrate pretty strongly, through the chassis (not the steering wheel). Once I let off of the gas, it goes away 95%, the second I step back on the gas, it comes back.
U joints are fine, front and rear, I've checked them twice. I've tried rotating the tires to rule that out, no difference. Fluid levels are fine in the trans, xfer case, and diffs.
XJ is a 91 Limited with 2.5" custom leaf pack rear, spacer front, Bilstein 5125s, boxed control arms, 242, and 241k miles. Car drove fine with the lift until this developed.
I noticed that the motor mounts look like they are sagging a bit (I can fit my finger between the rubber and the top on the passenger side). Would that have anything to do with this?
Any ideas? Thanks!
