On Armada models equipped with a rear auto-leveling suspension, turn the ignition key to the OFF position before raising the vehicle. With the front wheels pointing straight ahead, loosen the front wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Apply the parking brake and block the rear wheels. Remove the front wheels. With the ignition key removed, secure the steering wheel in position with the seat belt or a holding tool. Remove the engine splash shield from under the vehicle. On 4WD models, remove the front axle assembly. The driveaxles can remain in place, supported by wire. Mark the relationship of the steering shaft to the Rack And Pinion input shaft, then remove the pinch-bolt. Do not disturb the small plastic cap on the Rack And Pinion input shaft if the Rack And Pinion is going to be reinstalled. Place a drain pan under the Rack And Pinion. Using a flare-nut wrench, disconnect the pressure and return fluid lines at the Rack And Pinion and allow the fluid to drain. On 2WD models, remove the front stabilizer bar brackets and lower the bar for clearance. Disconnect the tie-rod ends from the steering knuckles. Remove the Rack And Pinion mounting fasteners, then remove the Rack And Pinion. Installation is the reverse of removal. Be sure to tighten all fasteners. Tighten the wheel lug nuts. Add power steering fluid to the fluid reservoir, then bleed the air from the system. Have the front end alignment checked and, if necessary, adjusted.
