i've got a problem that i previously thought cuold only be cured(to my dealer$ delight!) by replacing my rear shocks.i have located a squeak/rubbing noise from my right rear shock bushing where it secures to the sub frame.does anybody know of a way to lubricate the outside of the bushing where the bolt goes through?a friend told me maybe a performance shop might be able to do this.any help is appreciated!!!!!
