i just use valvoline ls90 for the diffs, valvoline maxlife for transfer which is just an auto oil but if its the 6 speed manual transmission only use genuine jeep oil

Ditto, 6 speed, use genuine Jeep oil.

Re: Drive line service on 05 tj wrangler

Here are some torque values that you will need.
Assembly Specifications:
* Cover Bolt Ft. Lbs. 30-40
* Pinion Brg. Preload In. Lbs 20-40
* Pinion Nut Ft. Lbs. 200-220
* Ring Gear Backlash .005-.008
* Ring Gear Bolt to case Ft. Lbs. 45-60
* Side Brg. Caps Ft. Lbs. 70-90
Start tightening the pinion nut towards 200 Ft. Lbs. and check the rotation torque, If the preload starts tightening up too early or too late, compared to the nut torque, adjust the shims. Use an old pinion nut that's still in good shape to check the preload!Once that is set install a new nut and loctite it! Always a good idea to check gear/vendor manufacturers settings,they will vary, just to make sure there's no discrepancies.
