I recently installed a 2" spacer and shackle BB from Rough Country on my 99 (NP231) and now have bad driveline vibes. After spending hours searching through the forums I picked up an angle finder and discovered the following:
Output shaft angle is 5* measured on the flat part of the yoke ears.
Pinion angle is 11* measured from two different places on and around the diff housing and directly on the pinion yoke.
Driveshaft angle is 14*.
I see lots of postings stating that the pinion angle should be 1-2* lower than the output shaft angle. Unless I'm misunderstanding something, I would need an 8* shim to lower the pinion angle down to 3* (2* less than the output shaft).
What I have NOT seen in all my searches is anybody needing anything close to 8* for 2" of lift. Before I go and order shims I'd like to gather some feedback and make sure I'm not way off base here. Any thoughts, suggestions, etc. are appreciated.
Thank you!
