Uknown bearing part number
« on: September 08, 2025, 02:10:02 PM »
Hey everyone, I'm on the hunt to replace these bearings I pulled from the rear drive housing.
Seems like every rear-drive related parts diagram glosses over them. (Circled in red)
Anyone know what the part number is?

Once I had a Collie pup. Dug a hole and covered him up. Now I sit there by the hour. Waiting for a Collie-flower.

Hmm that doesn't seem to be it either.
My rear swing arm has threads where your diagram has bearings.

The bearings I pulled from my final drive look like this.

While the ones in the swing arm you linked look like this.

The BMW bearings fall apart because they have plastic bearing races that disintegrate.

Here's what the BMW factory bearings look like when installed.



Believe me or not. I don't care. I'm just trying to help you.
