If the vehicle is equipped with air suspension, turn off the air suspension system. The switch is located in the area of the right kick panel. Raise the vehicle and support it securely on jackstands. On 4WD models, remove the skid plate, if equipped. Remove the nuts from the link bolts and remove the link bolts. Keep any metal washers and rubber bushings in order, and be sure to keep the parts for the left and right sides separate. Remove the sway bar bushing bracket bolts and remove the bushing brackets. Remove the sway bar kit. Remove the rubber bushings from the sway bar kit. Inspect all rubber bushings for wear and damage. If any of the rubber parts are cracked, torn or generally deteriorated, replace them. When you install the rubber bushings on the sway bar kit, position them so that the slits face toward the front of the vehicle. Installation is otherwise the reverse of removal. Be sure to tighten all fasteners. CAUTION: New nuts should be used upon reassembly. On 2008 and later Expedition/Navigator models, it is suggested that the bolts (attached to plates) should also be replaced with new plates/ bolts. These components are assembled with high torque levels.
