    Q:
    How to remove and install a Steering Knuckle on Chevrolet Malibu? Posted by Yilmaz D.
    A:
    To remove the driveaxle/hub nut and wheel lug nuts, first loosen them. Then, raise the front of the vehicle and securely support it on jackstands. Remove the wheel. Next, remove the hub and bearing assembly. Disconnect the tie-rod end and balljoint from the steering knuckle. Disconnect the ABS wheel speed sensor electrical connector and detach it from its bracket. If applicable, detach the ABS wire harness from the control arm. Mark the strut to the knuckle and remove the strut-to-knuckle fasteners. Separate the knuckle from the strut. To install, follow the reverse steps of removal and tighten all fasteners to the specified torque.
