Rear end vibration on a lifted truck.

[Power Hungry]

Pinion angle, especially with a carrier bearing, can be a continuous cause of annoyance with lifted trucks. If it's not vibrating at highway speed, it's shuddering on hard acceleration. It is an absolute pain to get everything lined up correctly.

One thing we've had to do is build a spacer block to drop the carrier bearing a bit. Of course, this throws the front yoke off a little and may require dropping the tailshaft of the trans (via modified crossmember) to get everything back in line.

Lifts are a pain. It's just easier to cut 6" out of the fenders!!
