Ive been with two people on the afternoon the wheel bearing blew up.... No warning at all.... going along and then, grinddddddddddd,,,, more grinding........ more grinding........ I suggest you STOP instantly. I was with a buddy that we happened to be about 5-8 miles down a gravel road before we hit any black top. Once we got to black top it tore up all the components on the right hand non drive side. Ripped off the ABS, tore up the mount, hub, brakes, ABS plate, brake pad, disc vent plate, ABS ring, Etc. It really does a job on all those parts... It actually starts to machine itself into the rear hub when that bearing fails.
Pulling the bearings: When changing out the bearings I just tap them out with a big punch and then set them aside not to be used again. Then I have a bearing press to re install new bearings. I dont really care what damage I create on the old bearings because they are about to go to the recycle bin.
Im my Tenere experience. If you KNOW that you have a notchy / crunchy rear wheel bearing on a Tenere (and you have pulled it apart and then reinstalled the bearing) I would suggest you NOT ride it until they are replaced. Ive replaced many sets of wheel bearings and they can go at anytime, with no warning. If you decide to ride you might get 5 miles or 5000K miles before it blows up and fails. And depending on when you notice it you will have tons of damage and expense. If your tip-toeing town a gravel road when it goes you will hear it grinding. Hopefully you have a good AAA 'pick you up service'. If your cooking down the high-way and maybe listing to music when it goes, (rear) you will probably see the ABS light pop up first on the dash, then the engine light, and then all the lights on your dash will turn on and your speedo will go NUTS or just drop off to zero when your going 75...... ask me how I know this? By this time, once you pull over you will need a TON of new parts other than the $20 bearing.
The biggest issue is the little bearing on the right rear (non-drive). This is always the biggest culprit. The fronts use the same bearings and they tend to go south swell. With all the bearings Ive changed out before the "average" miles on these bikes (blown bearings) tends to be about 40K miles on that rear non drive. I have a friend with a high milage Tenere, the one mentioned above. We have changed out his rear right (3-4) times I believe. Two times it actually blew up and grenaded, one other time it was just preventative because it was a little notchy.
If anyone ever THINKS they have a notch, or drag, or "crunchy" bearing on a Tenere, please just change it out with a new one before you go ride more... Financially and safety, not worth it.
(soap box) don't power wash your bike, ever..... so many parts are ruined because of the high pressure water getting into stuff. It always cracks me up when people then reply, I stay far back so I dont mess up anything.................. LOL. What part of "ever" did you not understand... LOL
