ok so i had 4-4 drop the front springs have seemed to sag and i was getting sick of the rake. i bought belltech leaves and 3 in angled blocks and i still have the drive shaft vibration common with the extended cab s10s. i also installed airshocks if this has anything to do with it. im pretty sure its the pinion angle so what do i need to do to fix it? what degree shims do i need?

you should try the search button on the top right of the screen. If you have angled blocks, then shims arent necessary, the pinion angle is ok. The problem lies with the rest of you driveline angles. You need to shim the carrier bearing up a lil less than an inch. The object is to make all of the angles within 2 degrees of eachother. This meaning the angle of the trans output shaft, both parts of the driveshaft, and the pinion angle.
