If you're going to work on the rear end of a rear wheel drive vehicle with the wheels off, where do you put the jack stands? On a body-on-frame vehicle, is the frame preferable to the axles?

The owners manual and factory service manual list the appropriate lift positions, but don't mention where it's safe / not safe to position jack stands.

It depends what you are working on! If I were working on the axle, I'd put them under the chassis frame (or jacking points on a monocoque vehicle), but if I was working on the shell, brakes, diff etc I usually put them under the axle tube.

I generally either use specific jacking points, or try to position the stands as close as possible to the suspension mounting points - these, by definition, must be string enough to support the weight of the vehicle. The most important thing is to make sure the stands are secure and level, and that the weight is evenly spread over the pair, and over each leg of each stand, so there is no chance of the car shifting or moving on them - make sure to securely chock the front wheels as well!

If your jack stands are of the three or four legged type put some pieces of plywood under them if you have an asphault driveway.In hot weather they can sink into the tar and become unstable. –  mikes Apr 12 '12 at 21:02

Frame, jack points, solid axle are probably all fine for stands
