Last month I had the clutch replaced under warranty and immediately after noticed the pronounced driveline whine between 70 and 80 mph. I did a search here and elsewhere and came to the conclusion that the butyl strip on the carrier bearing was (1) not replaced, (2) replaced improperly, or (3) needed additional tape. This is based on the fact that the whine was not there at all prior to the clutch replacement. I mentioned the TSB associated with this problem and he immediately said it was wrong. Went on to say that owners bringing in TSBs make his life a living hell. I was only trying to be helpful in pointing to the actual problem area. Wow, did I ever learn a lesson, do NOT tell the service guys anything and let them waste their time as they see fit. Hmmm... I think they don't like knowledgable customers, maybe.
