Legacy models need special locking nuts added to hold the shock assemblies in place. With the trunk rolled back, Sedan drivers can reach the top mounting nuts from below, but Wagon owners must move the carpet from the wheel wells. First, make sure you loosen the rear wheel lug nuts, position the front wheels on blocks, lift the back of the car using a jack, and place sturdy jackstands to support it. Once done, you can take off the rear wheels. Put a floor jack under the rear part where the knuckle connects to the frame, and lift upward until you feel it reach the frame. Break the shock-to-knuckle fasteners, then lift the knuckle just a bit using a jack to unlatch tough bolts. The helper needs to keep the shock steady while you loosen nuts on top. The opposite of our removal steps, we start with the jack to match the shock hole with the knuckle hole, then tighten all components to their set torque requirements. Once you finish working on the wheels and bolts, you take the car down to the ground, and then tighten the wheel lug nuts to meet certain pressure requirements.
