Rear Differential Oil Change Questions...?

I'm going to change the rear differential oil in my '02 2WD Grand Cherokee w/ limited slip diff.

What is the tightening torque for the diff cover bolts?

To access everything the easiest, should I jack the jeep up by the frame and put it on jackstands to the suspension will uncompress or will driving the rear up on rhino ramps be enough?

If anything, jack the front up after you remove the rear pumpkin cover, to allow more oil to drip out. There is plenty of room to work without jacking the vehicle up. I always try to avoid jacking the jeep up, if I can avoid it, for safety reasons. The torque for my, much older jeep, is 33 ft-lbs.

I just did my axles and I torqued them down to 30 foot pounds.

you can always just pump out the old and pump in the new. It is very easy and takes about 15 minutes. The pumps can be bought at any auto parts store for about 3 to 5 dollars. The disadvantage of this method is you don't get it quite as clean as when you take off the cover. But for me, more frequent changes will occur the easier it is. I try to change it out every time I drive through deep water.
