rear wheel bearing noise

[peterbrown77]

The bearing spun in the hub and opened it up about 0.015".... I didn't have the usual bad-bearing rumbling, it would squeal for the first 1/4 mile. So I don't doubt that the hub was damaged beyond repair. I just question Porsche's design. Seems that VW/Porsche/Audi wheel bearings have always been trouble. Had a Jetta years ago that I kept changing wheel bearings on in sequence around the car.

thoughts on whether it would be necessary to change both rear ones if only one is making noise. Car has 33K miles on it. I will buy the extraction tool from pelican and keep it for future use anyway. Has anyone found one of equal quality cheaper than pelican? $275 seems pretty pricy to me.

A wheel bearing isn't a sort of thing that's going to leave you stranded on the side of the road in my experience. They give you plenty of warning and allow you to arrange time and tools. And it's a big job, even with the proper tool. I put in a rear bearing at 30k miles. I now have 46k miles and other bearings are still good. So I'd do them as needed.

I am always amazed at how much some people will do and spend to get a 5hp increase in performance. I wonder how much impact worn bearings impact performance. Surely a decrease in friction should increase performance. I replaced all 4 and do feel that the car performs better. I wonder if it would be quantifiable.

Eh, we had to replace the LF wheel bearing on my wife's Integra at 100k Miles. We put another 100k Miles on the car without ever needing to do the other side. Though they do seem to be more of a trouble spot on the Boxster, so if it helps you sleep at night......
