Rear Wheel Bearing..... Dry Grease
#16

Just a heads up, on those type of wheel bearings they have to be "Clocked" in exactly the right position for the inner races to come off with out damage to the bearing itself.
Just in case any one was thinking of taking them apart and putting grease in them and using them again.

Anyone know if its actually possible? I've got two bearings on my next shopping list (I figure with Porsche raising prices in January, I need to buy 'em now as they're not a generic bearing).
If my reading of it is right, Greg's comment flies in the face of what I've read elsewhere. If it is indeed possible (but very hard) to take them apart to repack, it would be good to know, before they become NLA.

I don't see how they can be removed without trashing the seal on the outside. The removal process includes extracting the stub axle from the bearing before there is access to the circlip that holds the bearing in the carrier. It takes the outer section of the inner race with it, so the seal is junk. So while it might seem from pictures that you could somehow repack and reinstall the bearing. But with that seal damaged, there's nothing to keep the grease in the bearing, nothing to keep dirt out of the grease that might remain in the bearing. Not sure what 'clocking' any part of that assembly bight do to save the seal.
Folks reading at home: More than 100k on your rear bearings or over 20 years old? Stock up on a few spares while they are still in the $100/each ballpark.
