Is there a trick for removing and reinstalling the rear hub? My park brake broke apart inside the rotor hat and broke the metal block which the brake shoes rest on. I would like to buy a replacement hub, but last time I loosened the the hub to replace the bearing I had heck of a time getting the hub back on because I'm fighting the bushing stiffness and aligning the bolt holes up. Is there an order to doing this or a magical height that unloads the bushings?
