my xj has a 6.5 inch lift and i would like to know what would be the best angle for my driveshaft i have an angle finder but im not sure what would be best. so i know what shims to buy.

Rear pinion angle should be parallel to your transfer case output angle. Front pinion should be pointing at the transfer case output.

What type of SYE/Rear Shaft setup are you running??
For a standard CV/SYE setup, your shaft should look like this.
For 6.5" lift you will need around 6-7* shims.

i've read this before that if you're not running sye/cv driveshaft that the rear pinion should match the tc output. is there a reason this is preferred over it being parallel to the driveshaft even if you're not using a double cardan? i shimmed my rear pinion (have stock slip-yoke design) figuring it would take care of 1/2 the vibration problem (and it does).Originally Posted by littleredXJ

At least 6 degree on the back with that much lift. Need a SYE also.
On different note, my front does not line up with the tc as shown in the picture. How can I tilt the diff. without screwing up the caster??

they say 1 degree for every inch but i would think 4 degree would work the best because if your using shackles as part of your lift they will tilt the diff a few degrees already.
