Adding Pinion Angle Shims - Tell Me If This Sounds Correct, Please

What Greg (TB) said

The way I read what you are contemplating, you have the two shafts parallel WITHOUT load. You want the two parallel UNDER load. So if the trans is 5 down (sounds like a lot, I agree with Greg, TB, I'd try and raise that) then you want the pinion down maybe 2 from the trans. So under torque, as the springs flex and the pinion comes up. they are roughly parallel

THIS is a quote from DrDiff

"



Pinion angle is the relationship between the transmission centerline and the pinion centerline, not to the driveshaft and not to the ground.
Ideally, the pinion should become relatively parallel to the transmission as the pinion wraps up under power. This is how U-joints are designed to run.
When the vehicle is resting on its suspension, make the pinion parallel to the transmission as a base line, then tip the pinion downward 2 degrees (for a street car). This is referred to as 2 degree negative pinion angle."
