Rear Wheel Bearing Advice Needed Please
 

Hi All,

I have finished the front suspension with new bushes (against advice I used poly) powder coat, paint, ball joints, rack, m mounts etc. Looks and feels the part. I've now come to the rear end and got the tank out and want to blast and powder coat / zinc the rear as well. Can I pull the rear apart without damaging anything like the bearings because they are still good. In fact the shocker pin came straight out. Had lots of anti-seize on it. I'm kinda thinking, in for a penny in a for pound and just replace them anyway. I'm also wondering whether now would be a good time to drop the gearbox and T.T and do all that. It will mean the car ill be off the road longer as money is a bit tight at the moment (nasty shoulder injury). Not that that worries me, I'm just itching to drive it.
Any advice / tidbits would be greatly appreciated. It's getting frustrating working on this car because I can't undo some of the nuts / bolts due to the arm. Glad I have two fit lads.

A Happy New Year to all the folks here that make this a tight knit community. And for goodness sake please be careful and keep your wits about you on the roads. To many drunks this time of year.

Cheers Scott

Also forgot to ask, is it easier to get the hub nut off while it's still attached to to the car?

(The inside of the fender well will be cleaned up properly soon)

The parts look brand new,
i would have cleaned the fenders after removing the parts that you refreshed.
now the new parts will get funky from the the cleaning operations.

For the bearings if you remove the hub then the bearing needs to be replaced ,
you may be able to hammer out the axle then the hub will stay in the bearing.

I am not sure what your cleaning refurbishment is going to include for the hub carriers

The rear wheel hub is captured in the rear carrier by the rear wheel bearing. The hub is pressed into the bearing and the bearing is pressed into the carrier. The bearing is very beefy and consists of two rows of balls. It has one outer race but two inner races, one for each row of balls. If you feel like taking the hub out of the carrier, one of the inner races will come out with it. That pretty much destroys the bearing.

The bearing is retained in the Hub, not the Hub in the bearing. True on bearing is compromised when pushing the Hub out. The Hub is cast aluminum with a steel ring on the outside of the Hub which when removed exposes corrosion under this ring. Here's my S4 rear Hub I media blasted it and epoxy primed and painted in an Aluminum color paint so it looks original but won't corrode like the Aluminum will do. I am sorry you're currently and hopefully temporarily disabled! I had a spectacular motorcycle accident at the race track in Bryan College Station back in 2005, a Highside in T4 at about 80mph, broke my foot and I hated being immobile and layed up! Get well and get back on your 928.

Wow thats some of the most corroded parts i have seen,
the refinished parts look great

Really? I see tons of rusty and corroded stuff in my lane. This S4 was a Massachusetts car, then a NJ car, and ended up here in Texas where it was allowed to die with no glory and wrenched on by bubbas before the owner gave up and I secured it for a very reasonable price. Thanks on the compliments. You should see the TT, Transaxle, etc.

Or park them in a garage/cave with a natural aquifer rolling down the wall and underneath the car for 10 years. LOL

Wrong. The aluminum part is the "wheel carrier" and the steel part with the lug bolts in it is the "wheel hub." They are commonly called the hub carrier and the hub.

Ok, perspective. Feel good to start off correcting me? LOL! True, there's 3 pieces, but, I was talking about the big aluminum thing with a bearing inserted in it. Thanks for pointing out the Hub is the thing with 5 bolts sticking out for the wheel to go on. I'll remember this when I pull the body off my 1981 after I put the body back on my 1989.

Not "perspective," but perhaps PETspective, to coin a word. I only responded to your attempt to correct me with misinformation. If I am supposed to be impressed about the rest of your post, I am not. The body doesn't come off of the 928.

How's that again? Body does not remove from the car -- rather undercarriage?

I did all this because I can, and usually achieve anything and everything I put my mind to. Yeah, I only did this because the shift linkage was a little loose -- and I'll tend and have tended to everything else -- pics of it all assembled and clean coming next month or two.
