Raise and support car under the frame and rear housing so that they do not move when the control arm is removed. 2. Remove and install one lower control arm at a time. Use caution, the lower control arm has a load on it from the spring. Place a jack under the back of the lower control arm. Remove the rear bolt and lower the jack. Remove the front bolt and control arm. 3. Assemble and install one new lower control arm. Set the length of the control arm the same as the center distance of the stock arm. The outside diameter of the steel sleeve and the sides of the poly bushings should have a small amount of pre-lube applied to them. The new control arm should be installed in the opposite order it was removed. Attach Front, Place Spring on Arm, Jack Arm into Place, Install Rear Bolt. For ease of installation screw the spring seats all the way down. Do Not Tighten Bolts at this Time. 4. Repeat steps 2 & 3 for the other side. 5 Take the car off the jack stands so that it is sitting on the tires. Check the wheel base from side to side and the ride height. Adjust the wheel base and ride height if required. Tighten the jam nuts on the rod ends and spring seats. 6. With the car at ride height and all of the weight being supported by the suspension, tighten the front and rear nuts and bolts of both control arms. Note: Preloading the right rear can be done buy screwing the weight jacker up on that control arm.
