Rear wheel sensor replacement

repairpal.com/estimator Check there for a possible estimate relative to your location and the vehicle in your profile. If you are speaking of the rear wheel speed sensor or anti-lock brake system operation, it does not need to have the wheel bearing replaced with it. But, I would ask - it's unusual to need this sensor replaced. Is there some diagnostic testing that has been performed? Has wiring been checked first? I'd recommend a shop near you have a look to see what's going on. Good luck!
