I found out today what the cause was - workers on the line did not wash out the sand cast rear cases and sand is in the case eating at the bearings. It take milage to make the noise. Over 3K to be exact...Mine is effected along with a lot of early production models. I will have to replace ours as well.[/quote]
Do you have VIN numbers or production times on those that may be affected?
