Nissan 54010-ZR40A Front Spring

On Armada models equipped with a rear auto-leveling suspension, turn the ignition key to the OFF position before raising the vehicle. It is possible to replace the shocks or springs individually, but the unit will have to be disassembled by a qualified repair shop with the proper equipment. This will add considerable cost to the project. You can compare the cost of replacing the complete assemblies yourself to the cost of replacing individual components with the help of a shop. To remove, first loosen the front wheel lug nuts. Raise the vehicle and support it securely on jackstands. Remove the front wheels. Then, remove the shock absorber lower and the fasteners that attach the upper end of the shock to the frame. The lower shock assembly mounting bolt and the spring end should be facing outward. Remove the fasteners that attach the upper end of the shock to the frame. DO NOT remove the nut from the damper shaft. Turn the steering knuckle outward for clearance, then remove the shock absorber. Inspect the shock absorber for leaking fluid, dents, cracks and other damage. Inspect the coil spring for chips and cracks which could cause premature failure. Inspect the spring seats for hardness and general deterioration. If any of the components of the assembly are worn or damaged, have the unit serviced by a qualified repair shop or replace it. Installation is the reverse of removal, making sure the spring end is facing outward. Be sure to tighten the fasteners. Finally, tighten the wheel lug nuts.
