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.
