(I couldn't bring myself to use a "Flushing Rear End" title on this board. I never would have gotten past the jokes)

Anyway, I had the Ford 9" rear axle housing for my '68 project Camaro powder coated, which of course involved sand blasting it to get a good clean surface for the powder coating.

When I got the housing back, I spent a lot of time cleaning it using compressed air and rags, but didn't flush it out with any liquid.

I've been thinking about it and wondering how much, if any, abrasive sand may still be in my housing and how much damage it could cause. I don't want to be in the middle of nowhere with a cooked axle or differential bearing.

The housing, third member, axles, etc. are all assembled and the rear is installed in the car. I was considering trying to flush it with a solvent or other thin liquid, but I don't want to do more damage than I'm trying to avoid.

Any thoughts? And any thoughts on how I'd go about flushing the rear end (if that's the best approach) with it installed in the car?

Finally, am I worrying about nothing?
