Is it say to jack up our cars from the pumpkin with the torque arm removed? I have the front on wheel cribs and the back sitting on jack stands. The front is quite a bit higher than the back and I actually need to reverse them. As I lined up the jack I had a vision of the rear rotating on me and falling off the jack. I thought I'd just ask the question before making a mistake. Worst case...I'll use two jacks and raise both sides slowly

You can raise it from under the differential housing long enough to place jack stands under the rear frame rails.

I have no patience....

I reattached the torque-arm to the rear diff and then used ratchet straps attached to my inner subframe connectors to hold it in place. Worked just fine!
