I find this confusing because there are 8 different methods/opinions on the subject .

SO--lets try a new approach. Im going to post my measurements and lets see if everyone comes up with the same number in the end .

Here we go:


d-shaft at rear angle 86 degrees (4 ? ) DOWN measured on bottom of shaft. D shaft is pointed down at rear.


pinion flange 81 degrees (9 ? ) DOWN vertically measured . pinion is pointing down .


trans seal - measured vertically 88 degrees (2?) UP .


pinion yoke (u joint cap) 5 degrees DOWN


so ... what is my pinion angle ?
