    Q:
    How to raise the rear of the Pontiac Firebird and remove the rear Shock Absorber? Posted by Inez H.
    A:
    Raise the rear of the vehicle and support it on jackstands. With the rear seat folded down, carefully lift the front edge of the rear panel carpeting and fold it back to expose the rear shock upper mounting nut. Hold the top of the shock piston with one wrench while removing the upper mounting nut with another wrench. Remove the lower shock absorber mounting nut and take out the shock. Installation is the reverse of the removal procedure. Tighten all nuts and bolts to the specified torque.
