Output shaft seals: A word of caution When shopping for differential output shaft seals, many people use the Timken cross reference website that gives a 239146 part number for this seal in a small case diff. This number is incorrect. The part you end up with when using this number is almost 1/4" too small in diameter. Unfortunately, this number is also used by Carquest, Autozone, Advance, and Rockauto. If you need this part, go straight to BMW. I'll post pictures later of what you get vs what you need. __________________ Last edited by Entropyman; 01-22-2012 at 09:51 PM. Reason: grammar & spelling |
