I am waiting on the result of my BMW shop checking my bearings under warranty for free after I have put 4000 hard miles (dirt, sand, rain, 600 miles in one day, etc) on the new bearing they put in a couple weeks ago. If these are defective I will pressure them to report to BMW (and I will as well) there is a problem with the hub. I still have no plan if I don't get a new hub, etc, but I will not be attacking my hub with sandpaper etc...
I agree. I thought about the brake cylinder hone, but decided against it. That tool is simply not designed for that purpose - there is no way to keep the axis of the drill perfectly parallel to the axis of the wheel. You might get lucky, and you might bugger the wheel. I would go with Cisco's advice and get a competent machinist to do the work with the right tool.

I just got back from delivering my F800GS to Wild West Honda/BMW.

They looked at my bearings and agreed that the rotor side was not in good shape. They contacted BMW and BMW just delivered:
  • hub
  • bearings
  • seals
  • axle
  • circlips
  • adjusters
I'll pick up my bike from them next week and I'll fill in the rest of the details. What surprised me was that BMW sent a hub instead of a whole wheel. My original wheel will be laced to the new hub.

When you get the invoice, please let us know what the part number for the hub is so we can see if it's a different hub.

Did you happen to ask if they've heard of any service bulletins on the rear hubs?

Thanks for the reminder. I didn't think to ask anything today. I'll get the whole scoop when I pick it up.

Looks like the cat is out of the bag. If there isn't any problem with the hub why would BMW send a new hub and pay to have it re-laced to the old rim.

Wounder what my dealer will say know.

I forwarded this thread to my dealer. Though I can NOT definitively say so, I got the hunch that they had some knowledge of this issue as they kinda finished my sentence when asking for them to check the bearings out.

Anyway, I put on new Hidenau K60s and had them check my F & R bearings. All bearings checked and reported as fine and in good shape. I ensured they put this down in the service write up should it show up in the future.

'09 F800GS with a build date of Oct. 16, 2008.

Are there any 2010s out there with enough miles to have seen this problem?

Any 2010 models with bearing problems?

I asked that very same question a few weeks back. Only one person said that he may be having bearing problems with his 2010 f 800 GS. So far I have only heard of one 2010 model that may have had bearing problems but I would imagine the 2010 bikes (built in 2009) may not have put on enough miles for it to develop bearing problems (if the hub problem still exist). I am hoping that the problem was with bikes built in the summer of 2008 and the problem has been corrected with bikes built after that time frame. I apologize to those who purchased the 2008 models and had bearing trouble. I feel for ya. We'll see?LP

Loose tolerances on the manufacturing drawings... A lapse in quality control... Worn out tools... An incorrectly specified bearing... Who knows what created the crush but if BMW fixed the problem and did not roll out a service bulletin that is mighty shady. I believe this is an undiscovered issue for them until the complaints rolled in. With loose specifications the test bikes may have been OK, many bikes may be OK... All I want is my fix and to be out on the open road!!

It would be very interesting to measure the new hub.

it would be more interesting to measure a random sample of all 2008, 2009, 2010 hubs.

Wonder if hub replacements will be a standard part of the deal now, and if so, if they'd let you lace a rational size rim on there (at your cost for the rim itself) instead of that oddball hoop that came standard?

Yeah. It'd be cool to get an 18 on the rear & a narrower front rim as well. Also wondering who's doing the building? The shop or a wheel specialist??

Wild West Honda/BMW was happy to let me send my hub to Woody's Wheel Works to lace up an 18" rim, and that was precisely what I was going to do. Unfortunately, at the last possible second I had a financial catastrophe and couldn't afford to do it - much to both of our disappointments (mine and Woody's).

Just looked at your original post:

Did you have more damage than just crunchy bearings? Was the axle part of the front axle recall or are you talking rear axle? Why in the world would they send new adjusters? Hmm.


WRT a new hoop, I'd probably have the shop lace me a new one if offered, since they'd already be doing the labor, all you'd need is to order a new rim, rather than deal with all the shipping and outside labor. But I'm cheap.
