Disconnect the pressure and return lines from the steering gear. Plug the

coupling. Remove the bolts that secure the flex coupling to the steering gear
and to the column steering shaft assembly.
Raise the vehicle and remove the pitman arm attaching nut and washer.

To install:
Install the lower U-joint shield onto the steering gear lugs. Slide the
upper U-joint shield into place on the steering shaft assembly.
Slide the flex coupling into place on the steering shaft assembly. Turn
the steering wheel so that the spokes are in the horizontal position. Center
the steering gear input shaft.
Slide the steering gear input shaft into the flex coupling and into place
on the frame side rail. Install the attaching bolts and tighten to 50–62
ft. lbs. (68–84 Nm). Tighten the flex coupling bolt 30–40 ft.
lbs. (41–54 Nm).
Be sure the wheels are in the straight ahead position, then install the
pitman arm on the sector shaft. Install the pitman arm attaching washer and
nut. Tighten nut to 170–228 ft. lbs. (230–310 Nm).
Connect and tighten the pressure and the return lines to the steering gear.
Disconnect the coil wire. Fill the reservoir. Turn on the ignition and turn
the steering wheel from left to right to distribute the fluid.
Recheck fluid level and add fluid, if necessary. Connect the coil wire,
start the engine and turn the steering wheel from side to side. Inspect for
fluid leaks.
