Ford F75Z-5560-CA Coil Spring

The process only works on sport utility vehicles when replacing the coil spring for pickup models and 2004 and earlier Expedition and Navigator models. Start by loosening the rear wheel nuts, then lift the back side of your car and make sure it's supported and blocked on jackstands. Keep all four front wheels from rolling by blocking them. Climb under your vehicle and take off both rear wheels before removing the driveshaft. Use a wrench to disconnect the electric connection for the rear sensor, let the parking brake mechanism go freely, relax the cables, then remove the parking brake cables from where they attach to the parking brake levers on each rear brake caliper. Put the calipers aside and secure them carefully without cutting brake hose connections. Take off the tires to work. Remove the axel vent tube and the rear stabilizer bar from its connections. Take off the shocks' lower anchors, security hook for the driveshaft, and bottoms of the suspension arms from the axle using a floor jack underneath the differential. Loosen the coil springs while keeping the frame below your vehicle, and do not rebolt these until the car is back on the road. First, switch off your vehicle's air suspension system. Next, rotate your hand to loosen the nuts holding the rear wheels. Lift up the car's rear, place jackstands under it securely, and block the front wheels before lowering onto the jackstands. Lower the pressure in the suspension system by turning it off. Take off the retainer on back wheels, then lift and remove the bottom part of the air spring from the axle. Disconnect the electric wire from the solenoid, pull off the air hose from the air spring, and take out the air spring itself. After installation, you need to start the vehicle, let the compressor rebuild pressure until at least 1/8 inch of air line remains visible inside the solenoid. First start your vehicle, re-enable the air suspension, and let the compressor reach normal riding height when you're driving.
