I seriously would replace the bearings now!!! Which part of the axle is discolored? The Cush Drive bearing on mine was shot, and the left end of the axle was blue from heat. I didn't even realize there was a bearing in the cush drive! There have been reports of rear wheels locking up from hub bearings seizing... No joke, replace that bearing or bearings asap!! I've replaced all the bearings in my rear hub/cush drive, and also in the swingarm, in the last few thousand miles, to be on the safe side. Bike now has 43,000 miles.
