    Q:
    How to remove the Trailing Arm on Chevrolet Malibu? Posted by Saeed Y.
    A:
    To remove the trailing arm, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and detach the ABS wheel speed sensor harness clips from the trailing arm. Support the lower control arm with a floor jack and remove the trailing arm-to-knuckle nut and bolt, as well as the inner pivot bolt. Finally, remove the trailing arm from the knuckle and subframe.
