Have to get replace the brake dust shield. Only path appears to require
popping the rear wheel hub.

From what I tell, I will need a 36mm socket and slide hammer. Will
the removing the hub damage the wheel bearing?

I was also told to put the hub in the freezer before reinstalling so it
will fit easier in to wheel bearing.

When I reinsert the hub, do I just tap it in gently and let the hub nut
get the right seating?
