REMOVAL & INSTALLATION
See Figure 1
The backup power supply allows air bag deployment if the battery or battery cables are damaged in an accident before the crash sensors close. The power supply is a capacitor that will leak down in approximately 15 minutes after the battery is disconnected or in one minute if the battery positive cable is grounded. The backup power supply must be disconnected before any service is performed on or around the air bag.
- Disconnect the negative battery cable. If equipped with an air bag, disconnect the air bag backup power supply.
If equipped with an air bag, do not remove the steering column wheel and air bag module as an assembly unless the column is locked or the steering shaft is secured to keep it from turning. This will avoid damage to the clockspring assembly.
- Remove the two nuts that attach the flexible coupling to the flange on the steering input shaft. Disengage the safety strap and bolt assembly from the flexible coupling. If equipped with column shift, disconnect the transmission shift rod from the transmission control selector lever.
- If equipped with column shift, remove the shift linkage grommet and replace with new using shift linkage insulator tool T67P-7341-A or equivalent.
- Remove the steering wheel and the steering column trim shrouds.
- Remove the steering column cover and hood release mechanism directly under the column.
- Disengage the electrical connectors to the steering column switches.
- If equipped with column shift, loosen the four nuts holding the column to the brake pedal support, allowing the column to be lowered enough for access to the shift indicator lever and cable assembly.
Be careful not to lower the column too far, so the plastic lever or cable is not damaged due to the weight of the column.
- If equipped with column shift, reach between the steering column and instrument panel and gently lift the shift indicator cable off the cleat on the shift indicator lever. Remove the shift indicator cable clamp from the steering column tube.
- Remove the four screws that attach the dust boot to the dash panel.
- Remove the four attaching nuts holding the column to the brake pedal support. Lower the column to clear the four mounting bolts and pull the column out, so the U-joint assembly will pass through the clearance hole in the dash panel.
- Install the steering column by inserting the U-joint assembly through the opening in the dash panel. Be careful not to damage the column during installation.
- Align the four bolts on the brake pedal support with the mounting holes on the column collar and bracket. If equipped with floor shift, attach the nuts and tighten to 20-37 ft. lbs. (27-50 Nm). On column shift, attach the nuts loosely, so the column will hang with a clearance between the column and instrument panel.
- Engage the electrical connectors to the steering column switches.
- Engage the safety strap and bolt assembly to the flange on the steering gear (rack and pinion) input shaft. Install the two nuts that attach the steering column lower shaft and U-joint assembly to the flange on the steering gear input shaft. Tighten the nuts to 20-37 ft. lbs. (27-50 Nm).
The safety strap must be properly positioned to prevent metal-to-metal contact after tightening the nuts. The flexible coupling must not be distorted when the nuts are tightened. Pry the steering shaft up or down with a suitable pry bar to achieve plus or minus1/8in. (3mm) coupling insulator flatness.
- Engage the dust boot at the base of the steering column to the dash panel opening. Install the four screws that attach the dust boot to the dash panel.
- Install the steering wheel and the trim shrouds.
- Install the hood release mechanism and steering column cover beneath the steering column.
- Connect the negative battery cable. Check the steering column for proper operation.
See Figure 2
- Remove the steering column from the vehicle.
- Remove the lower U-joint, spring, sensor ring and bushing.
- Remove the turn signal canceling cam by pushing upward using a suitable tool. Note the direction of the flush surface.
- Remove the ignition switch assembly. Remove the upper snapring and coil spring.
- Remove the steel sleeve and ring. Remove the shift control assembly and shift control bracket, on column shift equipped vehicles.
- Remove the shift cable bracket on column shift equipped vehicles. Use a drift to tap the lock actuator cam pivot pin loose.
- Remove the plastic bearing retainer from the lock cylinder bore. Remove the metal bearing from the lock cylinder bore. Remove the ignition lock gear.
- Remove the two tilt pivot bolts. Use caution as the tilt spring will release when the bolts are removed. Remove the lock cylinder housing.
- Remove the steering shaft from the column assembly. Remove the column lock actuator. Remove the lower bearing and mounting bracket.
- Remove the tilt position lever arm pivot pin using a drift. Remove the lever lock arms and springs.
- Install the steering shaft into the housing. Install the lower bearing and column mounting bracket. Tighten the screws to 5-8 ft. lbs. (7-11 Nm).
- Install the sensor ring, bushing, spring and flex coupling to the steering shaft. Tighten the pinch bolt to 29-41 ft. lbs. (39-56 Nm).
- Position the lock actuator assembly in the housing. Position the actuator cam in the lock housing and install the cam pivot pin. Be sure the pin is flush with the housing.
- Install one tilt lever spring and arm into the housing. Install the outer lever spring and arm with the pivot pin. Tap the pin in place while driving out the drift.
- Support the housing in a vise and drive the pin flush with the housing. Position the two nuts or spacers to hold the tilt lock arms away from the housing.
- Position the tilt spring on the lock housing. With an assistant, install the lock housing and pivot bolts. Torque them to 14-20 ft. lbs. (19-27 Nm). Lube the pivot bolts with grease before installation.
- Install the steel sleeve and ring gear over the steering shaft and onto the upper bearing.
- Install the spring and a new snapring on the top side of the spring using a 3 / 4 in. X 2 1 / 4 in. (19mm X 57mm) PVC pipe. Install the turn signal cancel cam, flush surface UP.
- Install the ignition switch. Align the pin from the switch with the slot in the lock/column assembly. Position the slot in the assembly with the index mark on the casting. Torque the retaining screws 5-8 inch lbs. (0.6-0.9 Nm).
- Install the ignition lock gear. Coat the gear with grease before installation.
- Install the metal bearing. Coat the metal bearing with grease before installation.
- Install the plastic bearing retainer. Install the shift control tube assembly. Coat the bushings with grease prior to installation. Torque the retaining screws 5-8 ft. lbs. (7-11 Nm)
- Install the shift cable bracket on the lower column bearing assembly.
- Install the steering column in the vehicle.
