Pinion angle, revisited...

Re: Pinion angle, revisited...
An angle finder placed on the output shaft's u-joint gives the t-case's
output shaft angle. Then the plane of the axle's pinion angle can be
found with the angle finder placed at the rear of the axle housing on
one of the two circular points which is perpendicular to the pinion
shaft. Since the angle finder has two flat planes 90 degrees apart from
each other, the angle finder can be rotated so it can be at the same
angle it was when measuring the t-case output shaft. Then move the
pinion up or down until it's at or 1-2 degrees under that of the t-case
output shaft. At least that is how I get a pretty precise measurement
on them. :)
