The gear inside the transfer case actuator can wear out, causing the symptoms described. The actuator motor attached to the transfer case contains a low-quality nylon plastic gear that is driven by a metal worm gear. Over time, the nylon gear wears down and strips, preventing proper rotation and leading to the described issues. Install our improved design actuator gear to restore function to your actuator motor. Replace the worn nylon gear with our durable replacement made from a plastic and carbon fiber mixture. This repair resolves the issue and avoids the expense of replacing the entire actuator motor, which may fail again. This is a high-quality, precision-made replacement part constructed with enhanced materials for improved performance.
