Spinning dry also damages the bearings. There is no lube to protect the
surfaces and normally some dirt left. Spinning with air spins the bearing very
fast and accelerates the wear process. When I worked on jet engines a bearing
that was spun with air was automatically taken out of service. I know that
cars don't have the same tolerances but why take the chance of extra wear?

That would be a safety issue. Long time ago a friend of mine was working on his
racing go-cart and spinning a dry bearing with the air hose. It blew apart and
he lost his left eye. It is now made of glass. I learned my lesson from him.

I've heard this for years and don't do it. But it is blind acceptance of the
advise. I've never found an acceptable explanation as to why. Anybody have one?
