Cleaning up an axel housing
I've spent between 2 hours and 6 hours per housing wire-wheeling 8 3/4's. If I had access to a sand blaster that was big enough-- I would shove one in there so damn fast it would explode like a torpedo.
You may be stuck with wire-wheeling my friend. Been there... Get your mask and glasses (don't breathe the dust!) and prepare for sore forearms and shoulders for 3 days.
Good luck.
