Exactly how do you calculate a diff/final drive ratio (without counting gear teeth)? I put a mark on the drive shaft near the diff housing and some tape on a rear wheel relative to the edge of the body/sill. So the final drive is the number of rotations of the drive shaft produced by one wheel rotation? I multiplied this by 10 to get some better accuracy and 10 wheel rotations produced 22 drive shaft rotations (in neutral). FD = 2.2 therefore???!!!@@## It has been a long day and the brain is obviously missing something very simple ....
