[QUOTE="Stitch, post: 3028865, member: 4872"] Honestly, I'm no expert nor a mechanic. I've done alot of research and only have experience with my problems. I don't know why the pinion angle changed, all I know is it was way off afterwards and I had a nasty vibration over 70mph. After raising the pinion angle to 90 (before adjusting the tranny) the vibrations diminished. That told me and my mechanic that we were getting warmer. After doing more researching and figuring out that the pinion angle/crankshaft angle needed to be less then 1*, we settled on raising the tranny some to compensate since the bushings from KB weren't getting me anywhere above 90* for above stated reasons. I'm not sure how high the tranny can be raised nor do I want to go extreme either way. I'd rather raise both a little then one a lot. My vibrations are still there but much less then before. I'd say but 85% less. Without tearing down the rear end again, I have no other information as to what could be causing the vibration or why the pinion angle was wrong after the install. [/QUOTE]
