Pinion angle

THAT was quite an example, hard to wrap my head around it. I just assumed all parts would be moving equally. So on a lifted 4x4, with an extreme driveshaft angle, all is well if the rear end yoke and tranny are in line?

Well you're close............??? Normally the angles (engine and yoke) are set so that when there is a load on the drive train (during acceleration) the tranny and yoke are at the same angle. So if you set your pinion angle with the car sitting still (static) you need to have the yoke about 2 1/2 degrees down relative to the engine/tranny angle. Now other people might say 2 degrees and some might say 3 degrees ....to each his own. The point is that when you accelerate the pinion yoke will rise up a degree or 2 at which time it will be at the same angle as the engine/tranny. Make sense??
