CAUTION
The suspension on any vehicle is assembled with high grade, hardened fasteners. NEVER substitute a fastener of inferior load rating when assembling a suspension component!

These vehicles use two control arms on each rear wheel. To avoid confusion, the arm closest to the front of the car will be referred to as the front arm. Refer to the exploded view of the suspension components.
