Default Front pinion angle adjustment
Hi guys, I have a 00 XJ that is lifted 6 inches. It has adjustable lower control arms on it, stock upper control arms. I was wondering if some one could tell me how to adjust my front pinion angle. I seem to have a bad vibration when using 4wd.

Extending the lower arms will rotate the pinion down and visa versa.

Got pics of the drive shaft to pinion angle?
With a 6" lift your most likely gonna need long arms for sure. I never saw anybody running stock uppers on a 6" lift.

Pinion is Waaaaaaaaaaaaaaaaaaaay to low.

Shorten the lowers or extend the uppers.

Your caster angle should be 6-8 deg., steering wheel might need to be recentered.

Setting the caster will put the pinion at the correct angle.
