Something came to mind. Transmission down 2.5°, pinion up 2.5°: on acceleration, won't the rear end want to climb (rotate) up more than 2.5°? And while driving, with the rear wheels propelling the car forward won't the pinion be up more than 2.5°? Will that cause a problem? Or am I over thinking this?

Edit: 340Shorty said what I've heard too. That's why I was wondering...



That is wrong with the trans down 2.5 and the pinion up 2.5. That would be 0 pinion angle. You want a difference of 2 to 3 degrees down so when the pinion wants to go upward on acceleration it goes closer to 0 but not 0 as you want some angle so the U-joints will work and move the lube around in them. If you had a trans say 2 down you would want the pinnion 4 or 5 down for 2 to 3 down pinion angle. Ron
