While riding yesterday, when just rolling along at about 3k revs in second gear I noticed a harshness in the drive line.
When I got home I put the bike up on the stand to lube and adjust the chain (my first thought was a dry or badly adjusted chain). The chain was okay, but when rotating the wheel, I could hear and feel (through the wheel) a harsh scraping/grinding noise. I removed the chain guard, and the sprocket and chain (to eliminate them as a source of the noise) but the noise remains. It is totally unlike the noise of a brake pad dragging on the disk so I doubt that is the cause. I am thinking wheel bearing..........It feels like a dry or failed bearing. The noise only occurs over about 45 - 90 degrees of a full wheel rotation.

Does any body have any ideas, or experienced anything
similar. The bike is 4 months old and has done 6k.

Today is a holiday, and the weather is perfect.....I should be riding.....

I think a pranged bearing is a good suspect, in my unprofessional opinion.

Unfortunately, looking at the shop rag (for my 2004 mind you), replacing bearings is more involved on the S3's single-sided rear wheel than a standard wheel. Normally you can drive the bearings out with a drift, but on the S3 it takes a press to get the bearings out.

So it's either take the hub assembly off and down to a machine shop, or replace the whole unit. In your case sounds like a warranty claim and therefore the shop's problem :-D

Good luck, and hope you're back on the road soon.

I do not want to hear that from you, buddy.

Trailer to the dealer ASAP.

Legman · 11-01-2005

Yes. I will ring the dealer tomorrow, and trailer the bike over as soon as they can look at it. I will post the outcome!

24 hours after trailering the bike to the dealer, the bike was ready to pick up complete with new bearing.

Good to hear you were taken care of buddy.
Hope it's not a trend. But since it's the first time I hear of such a failure, probably a fluke.

Certainly not enough for a trend, but I do know of a '03 S3 that had the rear wheel bearings fail and the result was that the wheel locked up at speed. Gladly the rider was just going down a straight when this happened so she managed to keep the bike upright.

It could have ended up in quite a mess if it had happened mid corner though.
