Description

Help get your four-wheel drive engaging properly again with this Dorman 4wd actuator, part number 600-103 from Dorman - OE Solutions. It is a front axle actuator designed to directly replace the original equipment part. It fits many vehicles, among them the 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy and 2002-2006 Chevrolet Trailblazer EXT. See the "Vehicles it fits" section for the full list.

The actuator engages and disengages the front axle when the driver shifts into and out of four-wheel drive. Dorman reverse engineered this unit to help restore proper function reliably. If you need a 2002 Chevy Trailblazer front axle actuator, this unit is listed for the 2002-2009 Chevrolet Trailblazer.

Direct replacement: designed to take the place of the original equipment actuator on the listed vehicles.
Effective fix: if a failed original actuator is why your four-wheel drive is inoperative, installing this one addresses that failure.
Smart solution: reliable fit and function at a competitive price.
Trustworthy quality: backed by a team of designers and engineers in the United States.

This part may need replacing if your four-wheel drive won't engage or disengage. Diagnose the cause before replacing the actuator, because switches, wiring or other drivetrain components can produce similar symptoms.
