I just replaced my front tire on 2012 DL650A (abs). After remounting the wheel (with wheel still in the air) I hear a slight noise when spinning the tire by hand. not sure if it is the brakes rubbing or the ABS sensor. I never bothered to spin the tire before I removed it so do not know if the noise is normal, or if I did something wrong in remounting the wheel. I greased the axle and both break assemblies are mounted securly. bottom line question is... should there be ANY noise spinning the wheel by hand when lifted off the ground?

The axle doesn't turn and the inner ball bearing raceway that touches it does not turn on it either. Greasing it has nothing to do with noise. It's a hold over from plain steel axles and bearings that could rust together.

Disc brake pads will touch the rotor and make a bit of noise when the wheel is spun by hand. At running speed that slight contact will go away.

I recently had a similar issue on my 2011 DL650. I had just removed the front wheel to install Rancho fork gators(Greywolf's recommendation). Went on a brief ride. When I returned I heard a very faint chirping which coincided with Wheel rotation ... once every rotation. I finally saw a slight discoloration on the front reluctor ring. I then was able to trace it to the black plastic sensor very slightly brushing the reluctor ring in places as it passed by the sensor. Don't know why the clearance closed up but it had. I rooted around in my spare washer collection and found a very thin copper washer that fit.
Then I ground it down as a shim until I duplicated the clearance on the rear brake. Problem fixed. I still don't know why the clearance closed up, all I did was take the front wheel off including brake calipers and sensor and re-installed.

Thank you. I went out and had a nice ride with the only discernable difference being it was nice to have actual tire tread in the front! :) All is well, I appreciate the responses.

Did you shim the sensor too, or just the mounting bolt?

I just shimmed the sensor only to back it away from the reluctor ring and get it back to the original (sensor/reluctor ring) clearance. It's not lightly brushing the reluctor ring as it was before. I still don't know why the original clearance closed up but it's working fine now.

Cant believe I chased this problem so long. I used a copper washer from my stock brake lines on my KLR, not the best fit but the noise is gone so far. Measures perfect now and matches the clearance on the rear too, .025"
I couldn't even put the .005" in before and noise came and went. No marring on the plastic sensor, but it did discolor the ring some. :headbang::thumbup:
