ABS Sensor Ring is in the Wheel Bearing And Hub Assembly.


You have to put on a new one. May as-well do both sides and bearings too.


If you rotors are older you can replace them at the same time, which aslo means new brake pads. The wheel/brake caliper & mounts come off then, axle nut, take off hub & rotor, take new parts hub/bearings pack & put together install and take new rotor and install reinstall axle nut washer (most times you replace the nut too). reconnect any electrical connections, put wheel back on. This basic info so get a repair manual from parts store and follow all torque specs.


And do put the caliper hardware back on too.
