The fellow that made my driveshaft told me that I should try to keep the angles on both u-joints approximately the same and that they should be no more than about 5 degrees each. He said that u-joints that work at 10 degrees or more cannot be expected to last very long. He also told me that a u-joint that operates at exactly 0 degrees will also wear out more quickly than normal since the needle bearings are not moving around and they will pit the surfaces where they touch.

I used a magnetic angle finder to adjust the angles to about 3 degrees. Of course that is at normal ride height. The actual angles will change up and down as the car is being driven and the live axle moves.
