01 2500 dodge diesel. I need to know if I have 4 wheel abs brakes or 2 wheel. does anyone know or know how I can tell? I have to replace wheel hub assembly and need to know about the abs system. Thanks in advance.

 

remove front tire and look around the bearing hub and steering knuckle. you'll find a brake hose going to the caliper. if you additionally find a wire going to the hub or knuckle, then you have front abs.

rear abs is standard.
