pinion angle

pishta
So is the 5 degrees true for SS springs as well? I'm going to start over on my angles. Bad vibes from 5K up in high gear only. So if I have 1 degree down on the 904 output shaft and 3 degrees up on the pinion what should my shims be. This is not u-joint angle measurement. I measured on the pinion yoke. Do I need 6 degrees down on the pinion? What about the pinion snubber
Thanks,
