I did notice a bit more buzz at certain speeds from the diff but I had a nice radio and with it even at normal levels I couldn't hear anything. I thought it would be much worse than it really was with everything urethane. | What bushings did you use? I'm most concerned about the polyurethane RTABs...I heard without proper lubrication or self-lubricating bushings they can get very annoying. __________________
