Pinion angle, revisited...
 

Ok, I got under the TJ and dropped the pinion a little (adjusting the UCAs
accordingly). I still have vibration at 55+. This weekend I'll probably drop
it a little more to see if that does the trick... I guess the option is put
spacers on the t-case skid, but it doesn't seem like I should have to what
with the CV shaft and all...

Is there something I'm missing?

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...
 

Thanks Jerry... I'll probably drop the angle just a little more this
weekend. I did know the pinion needs to be pointed at the output, but it's
tough to see exactly where everything is pointed...

Re: Pinion angle, revisited...
 

Jerry,
How would one go about point the pinion shaft directly at the tcase output
shaft?

I think I would try to use a string that followed the plane of the pinion
shaft, and make sure I didn't break the plane by pulling the string at an
angle. But, how would one find the plane of the pinion shaft to establish
the line for the string?
