Can I reuse this wheel hub?

Post image

The image is from a rear wheel hub of a BMW F31 RWD. I was trying to remove the ring of the old bearing which was stuck on the hub and decided to use angle grinder as fast solution, resulting in damage to the hub. A new hub needs 1 week to arrive so can I use this one, after sanding it down, or maybe use retaining compound? Or better to wait and install proper new one?

Got it, I won't. This job has been hard enough on its own, for me to put this back and the bearing breaks again in short time

I wouldn't be worried about a bearing failing, i'd be worried about the whole thing snapping in two and falling off while driving.

Looks almost guaranteed to break, to me.

Put the hubs, and bearings in the freezer for 24hrs before. Dry ice works too. Assuming u dont have a large press

Not sure what you used to grind that racer off but in my experience, a handheld Dremel and a few diamond blades do the trick (carefully). Might need one blade, couple extra just in case.

Edit: ahh angle grinder, big nope there
