I have a 97 tj 4" lift 1". Transfer case drop I have a little drive line vibration I just ordered adjustable rear(upper) arms . With that said is the pinion angle on the rear to be adjusted to about 2 degrees lower on the rear than on the transfer case side to allow for proper alignment when I accelerate I don't have an SYE. Any input would be appreciated thanks

My understanding is that you want the rear to be in-line with the drive shaft. This is something I will be doing as well in the near future, and when I do mine, it will be set in-line on the rear.

I've found it best to have the pinion point directly at the output shaft of the tcase. When power is appllied the pinion will pull up and be in alignment with the shaft which is where you wAnt it.

"""""about 2 degrees lower on the rear than on the transfer case side to allow for proper alignment when I accelerate """""

That's a rumor. If your rear diff is loose and ready to fall out, it may be true. But it's for LEAF SPRING, not coils.

Unless you have a CV pointing it at the t-case will give more vibrations.
Measure the angle of the output shaft on the T-case point the pinion angle the same way.

If the DS bends 3 degrees at the T-case, it should bend the opposite way 3 degrees at the pinion.

Go to the Tom Wood Driveshaft site - he gives drawings and explanations at to why.
