Wheel bearings

Just wondering how often you'd expect to replace rear wheel bearings? I replaced the rear ones on my 09 pro in February and they seem to have some movement already. I ride for an average of 4-5 hours a week. Is this normal?

Are the wheel bearings a specific gas gas part or could I get them from a bearing shop?

Thanks

Yes, you can buy them from a bearing shop, just take the number off the old ones, or if you can't read a number take them with you

How long they last depends on the quality of the bearing and how you treat it.

When you get new bearings, before fitting them, carefully pick the rubber seal out of one side and pack the bearing with grease, preferably waterproof grease, then re fit the seal. If the bearing is stuffed with grease, it's harder for water to get in. also avoid pointing the pressure washer directly at the bearing

+1 on GII's advice.

also although generally you shouldnt overpack bearings with grease, i do fill up the wheel bearings.

They do oooze from the seals initialy... but the wheel generally isnt moving fast enough to worry and protection from water is improved.

Another thing to keep in mind is to not over-tighten the axles. Use the factory spec.'s and, as you should do with all fasteners on a competition bike, check them once in a while. Over-tightening the axle will put an excessive side load on the bearing, which it is not designed to handle.

I did not know that, and in fact thought that the presence of a center spacer would protect the bearing from side-loading.

Over-tightening can compress the spacer and lead to side loading.
