I just measured two of my trucks, they're both 3 degrees up and both 3/4 ton 2WD trucks. One is leaf sprung, the other is coil. One truck has a factory two piece drive shaft, the other has a factory one piece shaft, both trucks at factory suspension heights.This subject gets so blown out of proportion that the simple necessary facts get lost in the non-pertinent details, (BS)! HO-455 pretty well summed it up, we need more info! How many shafts? Automatic or stick? Motor and Trans on factory mounts and crossmembers? The bottom is, the crank centerline should be in the neighborhood of 3 degrees down. The pinion angle should match or closely match the same angle as the motor, only up not down. They should be looking at each other for the optimal set up... Two piece shafts are a little more detail oriented than one piece shafts. U-joints need to work in tandem, one counters the other. That goes out the window if that carrier bearing centerline is not inline with the crank centerline! Then the final two u-joints play in cancellation harmony...Why are you asking for pinion angles? Did you twist the trailing arm perches on the axle? I did that on Nasty Sally's 12-bolt when I put big block juice to the rusty factory mounts.
