Vibration at 3200 rpm and above need help

chasonmarose said

Ok so I narrowed the problem down to the driveshaft causing all the grief, I set it up on jack stands in the garage and watched it spin under various rpm ranges, driveshaft is a little out of balance now how Can I fix the pinion angle? How do u adjust that?

You will need to pull that driveline and get it straightened/balanced first, as you may not have a problem with angle.
Trying to do two things like that at the same time may not work out very well in the end financially.

Pinion angle is usually adjusted with angled shims between the springs and spring perches.
