The rear control rod bolts can be a pain: they are invariably corroded in place or very tight to remove. You will need an 18mm socket, a long extension, and a torque wrench. Remove the wheel and mount the car on a jackstand. You will need the access to hammer the bolt out with a mallet and reinstall it. Apply antiseize to the shaft of the bolt before reinstalling. Orienting the control rod bushing holes inside the body mounting bracket is also a pain: use a screwdriver through the side hole to twist the bushing so that the inner holes are aligned, then insert the bolt. Pound home. Some cursing will also help. Use Loctite on the rear nut and the front bolt.
Before you re-tighten both front and rear bolts, install the wheel, drop the car onto the ground, bounce the suspension to level it, THEN retorque the bolts. Turn the wheel to get the front bolt. The rear one requires a very long socket extension to torque it from the side of the car.
