CRP Transfer Case Actuator Motor Assembly

The CRP Transfer Case Actuator Motor Assembly (also called a transfer case shift motor or 4WD actuator motor) is an OE-quality replacement. It restores reliable switching between two-wheel drive and four-wheel or all-wheel drive modes. CRP markets this line under its Rein Automotive brand.

What It Does:

The actuator motor is a small electric motor mounted on the outside of the transfer case. When a 4WD mode is selected, the vehicle's ECU signals the motor to move the selector arms. The arms mesh the gears inside the transfer case and engage the front axle.

Key Features:

• Complete assembly developed in conjunction with the OE to work properly with the vehicle's ECU and the original transfer case
• Designed as a direct replacement for the original unit
• Ships with the motor, transmission component and the hardware needed for the application
• Helps resolve common failure symptoms such as a service or 4WD warning light, or being unable to engage or disengage 4WD

Replacing a failed actuator motor helps prevent the extra wear on tires and the transfer case that comes from being stuck in 4WD. It also avoids the loss in fuel economy that goes with that fault.
