Removing stub axle nut

[kwikt 911]

Your right. Servicing the emergency brake does not require bearing removal unless you want to.

Guys,

Remember this is a 930 with taper roller bearings for the rear wheel bearing.

Yes, first remove the axle assembly with stub axle attached.
Pushing on the stub axle while pulling on the hub may collapse the axial 'plunge clearance' of the CV joints and break the CV joint cages.

I would plan on fresh grease for the rear wheel bearings and new lip seals.

Best,
Grady

So why?

Your correct, normally any e-brake maintenance can be done after removing rotor. In my case the e-brake support plate has been damaged and therefore needs to be replaced. To remove the support plate the hub needs to come off first. What I thought would be a basic job in reality is a major job because it turns into a full rear wheel bearing replacement. That's because the the hub will not come out without damaging the bearing. If I pull with a slide hammer or drive it out through the rear I will pull bearing apart.. Outer part of bearing stays on hub ..see picture



That's just the way it is sometimes.

That is, unless there are two piece e-brake support plates. but of course there are not!

I've been cornfused by this thread, but maybe the 930 backing plate is different from mine. I took the backing plate off in order to pull my hub, and then replace the bearing with the puller.
