Roger, I think most folks remove the rear axle from under the car and bast it that way as it would be hard to control the sand from hitting the area around the axle, as well as it would be hard to get to the top of it.
I'm sure others will chime in.

Thanks Stan your right about the top but car would be hard to move around without wheels, don't want to try and blast in garage.

Your definetly going to want to remove parts like that before you blast them. Not just for getting in all the nooks and crannies, but especially when you dont want sand getting where its not wanted.
In order to really sand blast parts like that, parts most certainly have to come off and I also wouldnt even consider blasting parts like a rear end without dissassembling it first. Meaning, axles and gears come out and everything. You can seal it up as best as you can but when your sandblasting (key word is blasting, IE high pressure/velocity), those grains of sand will most certainly get where they arent wanted, namely, bearing surfaces.

Maybe you could make something to set on a pair of dollys and set the car on that. With rear removed you could take the control arms and backing plates off and sand blast them. You could use an abrasive wheel on a drill to get the rear axel clean and then paint. Another option would be to buy a cheap 10 bolt with control arms.

I've had 2 assembled rear axles blasted with good results. I run all the lug nuts on backwards to tighten the drums and then triple wrapped the drum to backing plate seam with duct tape. Also wrap the yoke seal seam and vent tube well and instruct the blaster to not blow thru the tape. I had a very small amount of sand in the drums after opening them back up and just blew it out with an air hose.
Trying to do this in the car would not only yield poor results but like Chris said, you'll have sand EVERYWHERE under the car. I have a pressure pot blaster and it is the messiest job I've ever done.

The other ones I have done or scene done were blasted THEN pulled apart for what ever work that needs to be done. That way you can see if any media entered the case and really concentrate on cleaning it.
