Recently picked up a 2010 F8 Sno Pro in excellent shape for a great price! Gotta love end of the year deals. This is my first "modern" cat and I hear a lot about the diamond drives. Good and bad. The guy I bought it from had a stack of receipts from having it dealer serviced every year. Drive oil has been changed every season and I plan to do it now before storage. There was nothing in the records about the single row bearing in the DD being upgraded to the double row SKF 3203 bearing. Since the season is over I plan to split the DD apart anyways. If it still has the stock bearing and looks good, should I change it? Or it's made it this far (3800 miles) so it's probably fine?
