replace rear wheel hub?

tried to change out my rear rotors and noticed that rotor screw was rounded (F*CK!)
had to drill out but inadvertently damaged the threading on the rear wheel hub.

Guessing i have to replace the hub now.. do i have to replace the wheel bearing also?

or anyone have any tips?

chase the threads or retap is your best bet.

If you change the hub you have to at the same time change the wheel bearing as the inner race will likely seperate with the hub.

You can chase the threads or get a time-sert kit.

You can also ignore it, that little screw is only ment to hold the rotor in place to allow you to put the wheel on and align the lug nut holes. The lug nuts and rim is what actually holds the rotor in place.

Taps can, but normally shouldn't be used to repair threads because they have a tendency to cut away fresh material.

Use a thread chaser instead, they look like taps, but are meant for the purpose of thread cleaning and repair (gentle reforming).

Agreed. No biggy if you don't fix it.

I wouldn't bother with the retaining screw. Not worth the trouble. And yes, change the bearings if pulling the hub. Inner race always seem to separate.

As a side note, the races are VERY easy to pop off. Take a grinder with a cutting wheel and score a notch on the top of the inner race. Then take an air chisel and hit the notch. It'll pop right out. You may get lucky and not have to even notch the race. They sometimes pop off with just the air chisel. Should only take a minute or two per race.

Good luck!
