ABS sensor attached to the hub assembly? Or can it be replaced alone?
on 2005 Chevrolet Silverado 1500

It looks like in this model the ABS sensor alone can be replaced without having to replace the entire HUB assembly (assuming it is in fact a defective sensor). Also How can you determine if its the ABS sensor or the ABS module?

Get your mechanic to scan test the abs system! Sensor itself can be replaced. Is it 4x4??
