Re: Pinion angle, revisited...
 

Making sure you know that the pinion shaft needs to be pointed
directly
at the t-case output shaft. Just make sure its angle is not above the
driveshaft either. 1-2 degrees under that of the driveshaft's angle is
a
good angle to aim at to counteract the minor effects of axlewrap on a
coil spring TJ.

Re: Pinion angle, revisited...
 

Don't you want the output shaft of the t-case and the pinion shaft to be
parallel? I thought the goal was to get these shafts parallel, not merely
pointed at one another. The t-case can have an angle of 3 degrees down while
the pinion has an angle of 7 degrees up, and the two shafts will be pointing
at one another. If the t-case and the pinion are both set at the same angle,
the u-joints will be able to do their job. (I just pulled these numbers out
of my ass, I did not mean to suggest they are the actual numbers you need to
achieve. My point was to illustrate that the shafts need to be parallel, not
that they be set to any specific number.)

I did not see anybody suggest that the u-joints needed to be in phase with
one another.

Re: Pinion angle, revisited...
 

Parallel only if the T case end doesn't have a double-cardan CV joint. If a
CV conversion is installed, the pinion agle should be parallel to the
driveshaft angle, hence the pinion should be pointing at the T case output
shaft.
