How to Remove a Rack and Pinion on a 2003 Ford Mustang

Rack and pinion steering was first introduced in the Mustang for the 1974 year model. This type of steering system uses a steering gear that is attached directly to the steering knuckle by tie rods, as opposed to the steering linkage found in earlier Mustangs. Replacement of the rack and pinion in the 2003 Mustang is a straightforward "remove and replace" project that is well within the average home mechanic's skill level. Normal safety procedures for Ford vehicles equipped with supplemental restraint systems must be followed to complete the repair without unwanted deployment of the air bags.

Instructions

1

Set the parking brake and secure the rear wheels with wheel chocks. Raise the front of the Mustang using a floor jack placed under the front K-member. Lower the Mustang onto jack stands placed under the lifting points located behind the front wheel openings, under the body of the car.

2

Disconnect the negative battery cable, using a wrench, to prevent unwanted air bag deployment. Steer the wheels straight ahead and turn the ignition key off to lock the steering wheel. Remove both front wheels.

3

Disconnect the outer tie rod ends from the spindle using a wire cutter to remove the cotter pin and a 18 mm wrench to remove the nut. Apply several firm blows to the steering arm until the tie rod end pops free.

4

Unbolt the rack and pinion from the front subframe using a socket and ratchet to turn the mounting nuts while hold the mounting bolt steady with a wrench. Slide the mounting bolts from the back side of the subframe.

5

Place a drain pan under the rack and pinion unit to catch power steering fluid that will drain from the lines and steering unit. Disconnect the power steering lines from the rack and pinion using an 18 mm line wrench.

6

Disconnect the steering coupler pinch bolt from the pinion using a 10 mm socket and ratchet. Pry the steering coupler off the pinion and slide the unit from under the car.

7

Slide the new unit into place and reconnect the steering coupler. Torque the bolt to between 20 and 30 foot pounds using a torque wrench. Install the power steering lines and torque the fittings to between 20 and 25 foot pounds. Install the rack and pinion unit retaining bolts and torque the bolts 30 to 40 foot pounds. Reinstall the tie rod ends and torque the bolts 35 to 47 foot pounds before installing new cotter pins.

8

Reinstall the wheels and lower the car off the jack stands. Torque the lug nuts to 100 foot-pounds. Remove the stands and lower the car. Reinstall the battery cable. Fill the power steering reservoir with fresh fluid. Have a front end alignment performed at the nearest auto repair shop.
