REMOVAL & INSTALLATION
- Raise and support the front of the vehicle safely using jackstands.
- Disconnect the steering shaft coupling.
- Mark the pitman arm-to-shaft relationship, then remove the pitman arm using a puller.
- Remove the steering gear-to-frame mounting bolts, then remove the steering gear.
- Position the steering gear to the frame, then install and tighten the frame mounting bolts to 70 ft. lbs. (95 Nm).
- Install the pitman arm while aligning the matchmarks made earlier. Tighten the pitman shaft nut to 184 ft. lbs. (250 Nm).
- Connect the steering shaft coupling, then tighten the coupling nuts to 20 ft. lbs. (27 Nm).
- Remove the supports and carefully lower the vehicle.
- Disconnect the negative battery cable.
- At the steering wheel, remove the horn ring or button.
Be sure to mark the relationship of the pitman arm to the steering gear before it is removed.
- Remove the pitman arm-to-steering gear nut, then using the puller tool No. J-6632 or equivalent, pull the pitman arm from the steering gear.
- Turn the steering wheel 1 / 2 turn from either stop, then loosen the sector shaft adjusting screw to eliminate the sector load.
Turning the steering wheel too hard against the stops will damage the ball return guides.
- Place an inch lbs. torque wrench on the steering wheel nut, then turn the wrench 90 degrees and observe the reading (measure preload). If the force is less than 5-8 inch lbs. loosen the steering gear adjuster locknut and turn the worm thrust bearing adjuster to increase the preload.
- Tighten the adjuster locknut and recheck the preload.
- Reassemble the pitman arm to the pitman shaft, lining up the marks made during disassembly. Torque the retaining nuts to 184 ft. lbs. (250 Nm).
- Install the horn cap or ring and connect the battery cable.
