I've been anticipating this day for the past few months. The persistent clicking sound in reverse has finally given way to silence. I guess tomorrow it's on to drop it off to Larry and George at GR Auto Care. Larry looked at it a couple of months ago and gave me an overview of the rebuild. It figures, I'm right in the middle of replacing all of the flooring in my house, and didn't need another cash outlay. Timing is everything!! I guess the M5 is back in the rotation for a couple of weeks.
