    Q:
    How to remove the Trailing Arm on Chevrolet Traverse? Posted by Ryo O.
    A:
    To remove the trailing arm, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Support it securely and block the front wheels. Remove the wheel and detach the ABS wheel speed sensor harness clips from the trailing arm. Use a floor jack to support the lower control arm and remove the trailing arm-to-knuckle nut and bolt. Make an alignment mark on the trailing arm adjuster cam to the subframe. Hold the adjuster cam bolt with a wrench and unscrew the nut. Remove the nut and cam, then remove the pivot bolt. Finally, remove the trailing arm from the knuckle and subframe.
