Rear Wheel Bearing on RT4

[KurtWildgrube]

Does anyone know what rear wheel bearing the RT4 uses? I’m looking to source something locally.

I can't tell you, but once you get it out, bearings typically have a number on them so you can easily cross reference the correct part. If the bearing is unmarked, go to a place like Applied Industrial Technology and they can match the bearing based on size measurements.

Thanks for the info, good point, I thought it to be the case but was hoping to have the part in hand prior to starting the replacement. I will be doing my best to capture part numbers and strategic sourcing on all of the replacement parts for the RT4 I come across.

On my RT4 (April 2022 build) it is a Schaeffler 805560A. On parts cross reference it comes back as a BMW 33416775842. Looks like they are fairly easy to source ($50), probably best to remove first and then order the new one. Note that it is a split inner so you'll most likely destroy the old one during disassembly. Also, the "craftsmen" at the factory didn't clean the parts before assembly so I had to take the full knuckle to a shop with a decent press. Once it was all cleaned up the new one went in nice and smooth.
