I need to replace the driver's side front wheel bearing assembly. After disconnecting the connector to the ABS sensor, do I also 'have to' unbolt it from the hub/wheel bearing assembly in order to remove the entire wheel bearing from the car ... or will it come out with it after just removing the 4 bearing mounting bolts?? The sensor is mounted with 2 small fasteners that get threaded into wheel assembly itself and I cannot tell if they pass thru the knuckle/strut assembly, in which case I would have to remove them?? They are badly corroded and it would be much simpler if I can remove/replace the entire assembly on the bench before reinstalling the new bearing assembly. (FYI - The wheel bearing assembly is held in with 4 bolts, not 3 and the flange has 2 tapped holes for the sensor).

Thank you in advance for your help!
