rear wheel bearings and new rotors

Greetings,


I know some of you guys just re-pack your rear wheel bearings when they begin to wobble. But what do you do when you get new rotors in the rear wheels? Get new bearings? Tap out the old races from the old rotors and tap them into the new rotor? Something else?


Thanks,
Justin

Bearings are cheap, replace them.

no one here has ever repacked a set of wobbly bearings, maybe some have tried but no one ever has had a case where repacking a bearing causes it to not wobble or make bad noises or remove excess play, not once, never. a chemical solution will never fix a mechanical problem.
buy a new bearing, hopefully the spindle is still good, if its not, you need a new spindle
we DO repack out bearings if the grease looks iffy or bad, or its just old AF ad your putting a new drum on with new races.

so yes, you buy a new drum, hope its not warped, drive a new race into it, regrease up the old bearing (if its in perfect shape. you can tell by cleaning them and inspecting for odd wear areas, should be uniform over each needle bearing. I often reuse bearings that are in great shape, especially if there the original OEM's
the issue is making sure your spindle nut is torques CORRECTLY with he proper sequence of weight and spinning. if you just crank down the nut, it will fail. 4 to 5 lbs on the end of a socket wrench, spinning the drum in reverse, loosening it and repeating this 3 times is the only way your going to get it right.

Mongler nailed it. 100%
