2005 Lincoln Navigator Rack And Pinion Parts Q&A

• Q: How to Service and Repair the Front Rack and Pinion on 4x2 on 2005 Lincoln Navigator?

  A: The procedure for 4x2 rack and pinion maintenance starts with setting front wheels to a straight-ahead position and turning off the ignition switch. A driver must switch off the air suspension control near the jack storage space in the passenger compartment rear section before any hoisting or jacking or towing of an air suspension vehicle because unexpected air spring inflation or deflation can shift the vehicle and pose safety risks. After setting neutral shift position, the vehicle should be positioned on a hoist. The hex holding feature should be used to stop the stud from rotating before removing two nuts to disconnect tie-rod ends from wheel knuckles. Begin by taking off the two bolts and the oil drip shield followed by disconnecting the lines from the frame rail retainers. It is crucial to avoid rotational movement of the intermediate shaft when it is separated from the rack and pinion since this motion could harm the clock spring; rotate the shaft if this occurs; the clock spring needs to be removed before recentering. The intermediate shaft-to-rack and pinion pinch bolt should be removed to disconnect the rack and pinion and intermediate shaft from each other with the power steering lines separated too. The O-ring seals will need replacement. The electrical connector disconnection for navigator vehicles requires rotating the actuator until it reveals the connector housing that faces the rack and pinion input shaft. Detach the two rack and pinion bracket-to-crossmember nuts and bolts before discarding them. Secure the steering lines outside the removal path of the rack and pinion before removing the two rack and pinion bracket-to-gear nuts and bolts and their accompanying brackets while discarding the nuts. In 4WD vehicles, keep the wheel end vacuum line away from the rack and pinion mounting fasteners prior to tightening the bolts for prevention of damage. Bolts attaching the bracket to the rack and pinion should be tightened first to prevent damage during subsequent bolts tightening between brackets and crossmembers (M12). The installation requires following the reversal of removal steps with new high-pressure line and return line O-ring seals and power steering system filling.
