R1100gs rear drive

[West coast gser]

Hmm .when Im cornering slow about 25/30mph I can feel like a grinding coming from the rear end .. Ive done the test for play in the drive bearing and there is none so thats ok .. there is a slight and I mean slight movement from one of the paralever bearings..any ideas what it could be causing the grinding feeling ? cheers

Squared tyres, even a couple of thousand off a Michelin can cause it

Slacken and re-torque (& re-grease) your paralevers anyway but it's probably just the tyres.

Is oil clean ? I had grinding and no play when change oil there was bit metal in it , bearing was starting breaking up .

2 bikes , twice is happy

I'd check tyres first. Is it worse when you just start off?

Yeah oils clean ..prolly give the bearings a tweek up ..hmm never thought about tyre ..its a conti trail attak was on bike when I got it ,its starting to square off now tho ..great tyre by the way theres no chicken strips on it .. ahem cannae believe the solid handling of the gs ..awesome either solo or 2 up ...

i cant see tyres causing a grinding noise,its more likely to be a bearing ,when you got a bit of side way force,if its a grinding/rotational noise its got to be the main bearing cage starting to fail ,change it soon before it goes altogether.its an easy enough job to do

Hmm .had a think about it and when I replaced one paralever bearing last yr I can't remember if I synched the shaft drive u/j's or not ..��

Well had the wheel off and rear caliper today and cant for the life of Me find anything wrong other than a slight movement of the paralever bearing ..no oil leak,misting or play from the FD so jus gonna ignore it n ride the blinkin thing .. ..

I agree that part-worn tyres are a likely cause - but I would describe the noise they make as more of a "gear whine" noise rather than a "grinding" noise
