I have 1990 GMC sierra 2500. i need to find out if it has abs brakes for axle replacement. - Visitor
Turn the ignition key to the "on" position if it has ABS brakes there should be a light on the dash that says ABS that comes on and goes out once the engine starts. Any garage or parts store would quickly be able to tell you by just looking into the engine compartment. - patrick mannion
