Rear wheel bearing on GSA

[morty]

Just had the beast serviced,can't complain only £210.On the report it stated the bearing felt rough.mmm do service techs have DTI's & load cells fitted as fingers? cos i'll be buggered if i can feel any roughness especially when its driving all the gubbings when you rotate the wheel.Granted I don't dismantle & repair bikes for a living (although I have had bikes all my life and stripped quite a few)but rough is not how i would describe impending bearing failure(must have a crystal ball).If i were testing a bearing it would have to be free from all the drive components connected there-in & its rotating with friction from the rear pads or am i missing something? I can accept you can feel free play but roughness to me means the bearing is fecked & it would have to be well fecked to be rough & don't use it till it's been replaced not carry on riding and see you in 10 days (apparently they can determine what level of roughness it is) .Don't get me wrong its covered under warranty and the bikes only done 14k.i just don't get how you can measure roughness with the wheel still interconnected & still say it's ok???makes me wonder if they're making dough from warranty work?? or am i being cynical?
feel better now i've got that off my chest.

Sorry. I'm on the phone.

Mechanic will most likely be saying that he can detect roughness in the bearing. He's just not added that rolling element bearings can be rough for ages before they eventually get slack and finally fall apart.

If he's had the FD separated from the driveshaft to grease the splines he may well be able to properly feel the wheel bearing for roughness..

It's just a fact of life that goes with owning an R1200GS. My first one required replacement at 18k and having just had it's 24k service I've been informed that there are signs of play (not yet excessive) in the final drive bearings again.
Pretty much every vehicle has it's Achilles heel and the final drive bearings just happen to be the GS's.
Luckily, it's been covered by warranty.

If you are getting a bit too much moment when you rock the wheel it would be best to throw a bearing and seal into it.
Its an easy job:
Bearing can be got anywhere: FAG 6013-2RSR-C3
Seal from BMW: 679 864 (inner)
Outer RH: BMW: 722-890 (this can be changed on the bike so don't change it unless its leaking).

Mine has just passed its MOT with an advisory on slight slack in rear wheel bearing. The tester said most BMW 1200s he's seen are the same so its nothing to worry about. After what folks say about them on here, who knows.

I'll have to get the centre stand back on the bike so I can keep tabs on that bearing.

I imagine that if the main wheel bearing is loose, the roller inside is also at risk from running out of alignment. I doubt that's an easy replacement, but a cautionary change of both bearings seems logical. Ive never done either job..
