Could us some help with pinion angle calculation on 67 Belvedere 440 with 8.750 rear diff vibration on deceleration at 75 mph
4* down on drive shaft 1*up on pinionWhat are your numbers now??
4* down on drive shaft 1*up on pinion
Threewood is correct. His reference is under Wide open Throttle. (wot) Although it is pretty hard to get those measurements at that time, he is saying the angles between engine/trans and pinion should equal zero at wot. Driveshaft angle does not come into play.Three wood, that’s totally *** backwards. The pinion raises under acceleration. Tranny down 3. Pinion should be do 4.5-6. Kim
If under wot then yes it is correct but he did not say if static or wotThreewood is correct. His reference is under Wide open Throttle.

Read sentence #2 again.If under wot then yes it is correct but he did not say if static or wot
I don't think he was measuring the angle at WOT. He was just making a reference to the fact that both should be parallel at that point. Where you guys are getting confused is the fact that he didn't mention axle windup and or adjusting the angle to make up for it. I was just saying that his statement is correct. It just doesn't tell the whole story.And just how is he measuring that at wot? No other way to tell for sure. Unless he has a crystal ball. Kim

U r correct. KimThe point is the center line of trans and center line of diff need to be as close to parallel at WOT so depending on springs and power the pinion needs to be 2 to 6 degrees down to counter axle wrap
