I am currently taking the weekend and devoting my life to my car literally I am about 15 miles away from home in a friend's boat shop, while everyone is away. I am living on peanut butter and jelly, and a six pack of coca-cola isolated from the real world. I only have a radio to keep me company. It's pretty sweet. Anyways I was just wanting to know if I had to grease up the outer edges of the poly bushings. Do I grease anypart of it that touches metal?
