When checking my rear wheel bearing i had a bad feeling an decided to pull the bearing (like a rotten tooth)
Suspicion was confirmed the grease was verry dry
Time to get a new one

Dan, that was on a '91? Now I'm wondering about the condition of mine. I haven't given any thoughts to wheels bearings up until now.

A good clue is how the hub spins. If it freewheels, the grease is gone.

How was yours, Patrick?

The bearings themselves are relatively cheap at circa $100 but putting them in is time consuming and can get expensive if the large pins do not come out easy.

A slide hammer hooked over one of the washers at the end of the pin makes it a breeze to remove the pin.

Just a heads up, on those type of wheel bearings they have to be "Clocked" in exactly the right position for the inner races to come off with out damage to the bearing itself.
Just in case any one was thinking of taking them apart and putting grease in them and using them again.

Bill, not that bad but it's a matter of time I guess. that's why i decided to do both sides.

Good point Roger.
No, those pins don't ALWAYS go out that easily!
Ask me how I know!

Reminder that some common (or uncommon...) front-drive wheel bearing extraction tools will let you do the job without removing the carrier from the car. I bought and use the Sir Tools setup and it makes rear bearing replacement relatively easy. I have one near Los Angeles (Rob Edwards is holding on to it right now). I think Dean Fuller has one in Mississippi, and Bill Ball was in the process of getting one last spring. The kit was a few $hundred to buy, so look around for a nearby kit. I'm sure there are other folks who have them too.

Okay so now I am paranoid and am gonna have to replace my rear bearings.

I did my right rear last winter due to some sound I could not locate. Turned out the noise was not the rear bearing, but when I pulled it out it looked very similar to what the OP shows. Just replace the bearings with new, but don't be an idiot and forget to put the circlip back in before you press the hub in. I was a dork and did that on my own, in the end it cost me two bearings for that one side.

I have never, ever, had to order three bearings to do one 928.
PS, don't ask any of our parts folks about that.

This list is great in making you paranoid and do un-needed repairs on your car.
So who has the tool and willing to lend it to remove and replace the rear bearing near NYC?

SeanR,

I'm experiencing a right rear noise that we attribute to be the wheel bearing. If yours was not the wheel bearing, can you share what you found out was the culprit?

Thanks in advance.....

Embarrassing to say what it really was, because it was my daughter that told me where the noise was coming from after I replaced the rear one.











It was the front wheel bearing.

The rear one was on its way out, but wasn't making the noise I thought it was.
