1G rear wheel bearings are designed very well, I have never even heard of one going bad, front wheel bearing failures are more common, that is just because people don't torque the axle nuts properly, which results in failure.
I personally HATE the 1G rear brake setup, ideally I would get two small calipers, one for the normal brake, another for e-brake, this would involve a hydraulic e-brake, but who cares
re-maned stockers for now.
