The actuator will need to be replaced however care must be taken when removing the actuator from the vehicle. If the internal portion of the actuator had completely separated the end of the actuator could become a projectile when removed. Obtain a number 8 self\-tapping screw that measures 1 ½ inches long.

Continue with the liftgate actuator by following the liftgate power assist actuator procedure in service information.
