First of all, to remove the rear axle assembly, turn off the air suspension system if equipped. Loosen the rear wheel lug nuts, lift the rear of the vehicle securely with jack stands, and block the front wheels. Disconnect the rear axle brake lines, vent tube, and brake hose. For truck models, position a floor jack under the differential case, disconnect the shock absorbers, and remove the spring U-bolt nuts, U-bolts, and spring plate. On 4WD models, remove the rear spring spacers while lowering the axle. For Expedition and Navigator models, remove the stabilizer bar brackets, lower the stabilizer bar, disconnect the air suspension system height sensor, and support the rear axle differential case with a floor jack. Disconnect the rear axle track bar, remove the rubber jounce bumper, and disconnect suspension arms and shock absorbers. Lower the axle assembly to the floor.

After removing the rear wheels, you should disconnect the driveshaft from the rear axle differential pinion flange.
