Output shaft seals: A word of caution

[Entropyman]

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.

good info...thanks a lot!

That's great to know. I need to do seals and bearings on mine very soon

[Entropyman]

Correct on the right, incorrect on the left.

[familytruckster]

Yikes, small difference.

What about the bearings? Did you source them from a parts house or BMW? AZ and most places say it's a pretty generic bearing (same as a ford 9")

Thanks for the info!

[Entropyman]

Bearings were no problem, I used Timken's from Rockauto. They were decently priced and well recommended.

[familytruckster]

Thanks again!

Let's hope that Advance Auto doesn't have a similar SNAFU with their axle shaft p/n's - I have a brand new pair sitting in a box in my garage that I'm sure are long past their return date.

Is the seal #6?

Yeah, it's number 6.
