Have the doc put in the recessed grease fitting so it won't nag on your pants and rip a hole in them. Takes care of the noisy hip. Use the same grease that you use on your boat trailer hubs. You won't need any bearing buddies however.

Sorry -sick joke. One of my friends (rip) used to assist in hip replacement surgery and would ask people what type of grease fitting they wished just to relieve some tension when getting them preped for surgery.
