I think I need one too!!!
How did you know you need a new carrier bushing? Just today on my way to work I heard a clicking coming from around the middle of my car. When I got near divider barriers I could hear in when I coasted or let off the gas. Got home and put the rear on stands and got under with a stethascope and thought it could be that, but the bracket that holds it to the underbody was quiet. Without the scope, I was sure the noise was coming from that exact area, and thought it might be some sort of ujoint noise from where the two shafts connect, but more likely the bushing. Man, the car shudders when I give it any gas, but keeps a steady speed OK. And did you ever find one? Do it yourself? thanks.
