    I have lifted my car several times under the differential. My jack has a thick rubber pad the distributes the load well over the base and does absolutely no damage.

    I don't like to, but I have a few times. Hasnt hurt anything so far. On my old R/T I used to a lot.

    I don't like using the diff as a jack point for anything on a vehicle with an aluminum diff. If you do, a block of wood or rubber is definitely a good idea IMO. Distribute the load as much as possible.

    I cut a 2x6 down for this very purpose. I wouldn't even consider metal on those cooling fins that are cast into the diff housing

    Standard procedure on every rear drive car I have ever owned but never had one with aluminum. The wood is a great idea.

    Nope, won't do it. To much weight for an aluminum housing

    I have a rubber pad on my jack and did lift the car using the differential. I noticed that the fins on the aluminum housing are not flat across the dif. so you do not get to spread the weight properly. I notice after I was done that it looked like the outside fin had cracked a bit. Luckily no oil leaking or anything like that but I will not be lifting it using the dif. ever again. Since the fins are cast they are more likely to crack than bend.

    Sorry you had to be the sacrificial rear diff. I guess I will not be doing it then.

    I considered it, but decided against it for the reasons cited above; instead, I use ZL-1 jack pads at the rear pinch weld jack points (both sides) and jack the car up evenly using 2 floor jacks.

    I have considered this also but now where do the jackstands go in the rear?

    You can slide the Zl-1 "pinch weld" jack pads slightly towards the rear to allow more room for your jack stands on the black pedestal pads which is what I do. (Note I use Esco #10499 flat bottom jack stands).

    Another option would be to use ZL-1 jack stops which would eliminate the need for jack stands; however, they are designed to be used with Pittsburg 1-1/2 ton floor jacks from Harbor Tool which are inexpensive and work great. Note: with this option I would add a jack stand slightly under the rear axle as a safety.
