These vehicles use a conventional power steering gear with a recirculating ball system. All tubes, hoses and fittings should be inspected for leakage at regular intervals. Fittings must be tight. Be sure the clips, clamps and supporting tubes and hoses are in place and properly secured. Inspect the hoses with the wheels in the straight-ahead position. Then, turn the wheels fully to the left and right while observing the movement of the hoses. Correct any hose contact with other parts of the vehicle that could cause chafing or wear. Power steering hoses and pipes should not be twisted, kinked or tightly bent. The hoses should have sufficient natural curvature in the routing to absorb movement and hose shortening during vehicle operation.

- Before servicing the vehicle, refer to the Precautions section.
- Set the front wheels in the straight-ahead position.
- Place a drain pan under the steering gear and disconnect the fluid lines. Cap the openings to protect the system from contamination.
-
Remove or disconnect the following:
Negative battery cableAdapter and shield from the gear and flexible couplingFlexible coupling clamp and steering box input shaft, matchmark for reassembleFlexible coupling pinch boltPitman arm to the Pitman shaft, matchmark for reassemblePitman shaft nut and lock washerPitman arm from the shaft using the proper pullerSteering gear to frame boltsGear assembly
To install:
-
Install or connect the following:
NOTECheck that the relationship of the flexible coupling to the flange is 1 / 4 - 3 / 4 in. (6-19mm) of flat.
Steering gear in position, guiding the input shaft into the flexible coupling. Align the flat in the coupling with the flat on the input shaft.Steering gear-to-frame bolts. Torque the bolts to 100 ft. lbs. (135 Nm)Flexible coupling pinch bolt. Torque the pinch bolt to 22 ft. lbs. (30 Nm)
Pitman arm onto the Pitman shaft, lining up the marks made at removal. Torque the nut to 215 ft. lbs. (285 Nm).Adapter and shieldFluid lines and refill the reservoir with the proper power steering fluid
- Properly bleed the system and verify no leaks.
- Road test the vehicle for proper steering system operation.

- Properly bleed the system and verify no leaks.
- Road test the vehicle for proper steering system operation.
- Before servicing the vehicle, refer to the Precautions section.
- Raise the vehicle.
- Remove the shield.
- Place a drain pan below the steering gear.

To install:
Fig. Recirculating ball gear
- Place the steering gear in position.
-
Install or connect the following:
Steering gear to the frame bolts. Tighten the bolts to 100 ft. lbs. (135 Nm).Pitman armIntermediate shaft
- Remove the plugs and the caps from the steering gear and the hoses. Connect the hoses to the steering gear. Tighten the hose connection to 20 ft. lbs. (28 Nm).
- Install the shield.
- Fill and bleed the system.
- Lower the vehicle.
- Raise and support the front end on jack stands.
- Remove as much power steering fluid from the reservoir as possible.
- Remove the engine under cover.
- On diesel models, remove the wheelhouse liner.
- Disconnect the hoses from the steering gear. Plug the lines to prevent leakage and contamination.
- Disconnect the steering shaft coupling from the gear.
- Remove the pitman arm nut, then separate the arm from the relay rod using puller J24319-B or equivalent.
- Remove the steering gear bolts and remove the gear from the vehicle.
To install:
- Install the gear in the vehicle. Tighten the bolts to 110 ft. lbs. (150 Nm).
- Connect the pitman arm to the relay rod.
- Connect the power steering hoses. Tighten the fittings to 24 ft. lbs. (32 Nm).
-
The remaining installation is the reverse of removal. Bleed the power steering system.
