    Q:
    How to remove the rear Sway Bar Kit on Cadillac DTS? Posted by Vanitecia H.
    A:
    Start by taking off the lug nuts on your rear wheels, block your front wheels, lift the back of the car, and set it on jackstands before you remove the rear wheels. Before working on the Seville or DTS, disconnect the bolt that connects the control arm bushing to the sway bar link, keeping track of how the bushings and washers are placed up front. Take off the bolts on the sway bar clamp and remove the whole bar. Before reassembly, open the clamp end and carefully pull out the bushings the same way they were when you removed them. Make sure to align all slit positions for the best results. Symmetrically tighten all wheel nuts and fasteners to their right torque setting the other way around.
