What is the removal process for the steering gear in Mercury Grand Marquis?

The rack and pinion removal process for 2002 and earlier models includes several steps. First, remove stone shields by unclipping the lock tab. Disconnect pressure and return lines, fluid line fittings, and pinch bolt on the flex coupling clamp. The Pitman arm should be detached from the sector shaft that supports the rack and pinion after removing it with attachment bolts. While installing, align the flex coupling on the steering shaft assembly so that its wheel spokes are horizontal. The rack and pinion mounting bolts should be installed and tightened. Return the Pitman arm back onto the sector shaft and secure the Pitman arm nut. Flex coupling to the rack and pinion input shaft clamp bolt shall be installed and tightened. Reconnect pressure and return lines securely. Fill the power steering system and bleed it out. For 2003 and later models, however, things are done slightly differently. Park with wheels straight ahead then loosen the front wheel lug nuts using a small wrench while raising the vehicle with jack stands with the parking brake applied. Place a drain pan under the rack and pinion unscrew the power steering pressure and return lines using a flare-nut wrench.

Mercury Grand Marquis Rack And Pinion

The Rack And Pinion on Mercury Grand Marquis cars is a very important part of the car which converts the rotational movement of the steering wheel into the lateral movement of the front wheels. This mechanism works with a pinion and rack system in which the pinion transmits force through a metal tube on the rack gear offering control on the direction to be steered. A majority of Mercury Grand Marquis models apply a power-assisted rack and pinion; this system applies a hydraulic support to improve the steering effort. This system uses a pressurised fluid triggering by means of a rotary valve and the degree of help as determined by motion of the steering wheel. As for the efficiency, straight gears are normally employed although helical gears might be used at the same times, having some disadvantages as for example wear. In the long run, some of these problems include leaking of fluids, wearing of gears, or damage of seals thus causing problem in the Rack And Pinion like stiffness of the steering or mere wandering. It is important that the steering system be taken for maintenance and other automobile service after a given period to enable it to do its premier and last longer.
