HRR!
I always had a fear of sandblasting partial subassemblies with some moving parts attached like that. I was told that sand gets in everywhere unless stuff you need to keep clear of the sand is well wrapped and tightly sealed from the blowing sand. Stuff like ball joints, brake drums, tie rod joints, etc, could incur major damage during normal operation if sand got in them. But don't take my word for it. Ask around and see if other folks of our ilk would have the same concern.
