you guys are making this too hard. the pinion angle is exactly what the name sounds like. it is the angle of the pinion according to the ground when parked on a level surface. what you are measuring is the operating angles of the u-joints which is important, but not the pinion angle.

So is there 2 different things goin on here? Pinion angle and operating angle?

Pinion angle just being the relation of the rear end to the ground

And

Operating angle whi h is the relationship between the rear end and drive shaft?

you can't just adjust your pinion down, and expect your driveline not to vibrate or break u joints... you have to look at everything.

I have never done it like that. I take a socket and place it on the cap of a u joint when it is pointing down and measure the angle. Do the same for the front and rear u joints.
