The little woman got herself a low end Schwinn cruiser from Target (I know that was her first mistake) she loves the look of the bike, but the coaster brake is noisy as hell. During normal riding it is fine, but when she starts to coast, not applying the brakes, it sounds like the internals on the rear hub are rubbing. She says she can feel a vibration in the cranks as well. I have done some searching and I think this may be due to the crap hub. She is going to try and see if Target can fix it, though I doubt it. Does anyone know some tricks that I could try to fix it? I have tried the adjustments Sheldon sugested but no help. Is it worth fixing or should I just take it down to the LBS and have them rebuild the wheel with a quality coaster brake hub?

TIA
