GEAR DISASSEMBLY INFORMATION
CAUTION: Cleanliness is extremely important when
repairing a power steering gear. Keep the bench,
tools and components clean at all times. Thor-
oughly clean the exterior of the gear with cleaning
solvent before disassembly. Drain as much of the
fluid as possible. Use protective vise jaws at all
times when clamping components. During assem-
bly, lubricate all components with power steering
fluid except where noted (Fig. 14).

CLEAN AND INSPECTION
(1) Wash all components in clean solvent and dry
with compressed air.
(2) Check for scores, nicks or burrs on the rack pis-
ton finished surface. Slight wear is normal on the
worm gear surfaces.
ASSEMBLE
(1) Install O-ring seal and teflon ring and lubricate
with power steering fluid.
(2) Install worm shaft to rack piston outside of
housing. Fully seat worm shaft to rack piston and
align worm shaft spiral groove with rack piston ball
guide hole (Fig. 33).
WARNING: MAKE SURE ALL RACK PISTON BALLS
ARE REINSTALLED IN THE RACK PISTON. IM-
PROPER INSTALLATION MAY RESULT IN PER-
SONAL INJURY.There are 24 balls in the rack piston circuit,
12 are black and 12 are silver (Chrome). The
black rack piston balls are smaller than the sil-
ver balls. THE BLACK AND SILVER BALLS
MUST BE INSTALLED ALTERNATELY INTO
THE RACK PISTON AND BALL GUIDE. This
procedure will maintain worm shaft preload.
(3) Lubricate and install rack piston balls through
return guide hole while turning wormshaft COUN-
TERCLOCKWISE.
(4) Install remaining balls to guide using grease or
petroleum jelly at each end to hold in place (Fig. 34).

clamp and screws. Tighten screws to 58 Nzm (43 in.
lbs.) torque.
(6) Insert Arbor C-4175 into bore of rack piston.

GEAR ADJUSTMENTS IN VEHICLE
REMOVE
(1) Raise and support the vehicle.
(2) Mark the pitman shaft and pitman arm for in-
stallation reference. Remove the pitman arm from
the shaft.
(3) Loosen the adjuster lock nut then back the ad-
juster plug off 1/4 turn.
(4) Remove the steering wheel horn pad.
(5) Turn the steering wheel in one direction until
stopped by the gear. Then turn back 1/2 turn.
CAUTION: Do not turn the steering wheel hard
against the internal stops when the linkage is re-
moved. This could result in damage to the recircu-
lating ball guides.
MEASURE
Place a low calibration (50 in. lbs.) torque wrench
and socket on the steering wheel nut. Rotate the
wrench and nut through a 90 degree arc (1/4 turn).
This will measure the worm shaft bearing preload.
ADJUST WORMSHAFT BEARING PRELOAD
TORQUE
(1) Adjust the preload by tightening the adjuster
plug. The preload should be 0.6 to 1 Nzm(5to8in.
lbs.) torque.
Steering column/shaft misalignment or damage will
increase the amount of torque required to rotate the
steering wheel. If the rotating torque is exceptionally
high, inspect the steering column/shaft alignment. If
the alignment is correct, remove the steering gear,
determine the cause of the high preload torque, and
repair as necessary.
(2) Tighten the adjuster locknut to 68 Nzm (50 ft.
lbs.) torque. Measure the preload torque. If neces-
sary, adjust the preload torque again.
ADJUST OVERCENTER DRAG TORQUE
(1) Turn the steering wheel from one stop to the
other and count the total numbers of turns. Turn the
wheel back in reverse direction 1/2 the total number
of turns to center the steering gear.(2) Turn the over center adjusting screw in to re-
move all lash between the ball nut and pitman shaft
sector teeth. Hold the adjustment screw and tighten
the lock nut to 34 Nzm (25 ft. lbs.) torque.
(3) Check the torque at the steering wheel by tak-
ing the highest reading as the wheel is turned
through the center position.
(4) The overcenter drag torque should be 0.5 to 1
Nzm (4 to 10 in. lbs.).
(5) If necessary, loosen the lock nut and adjust the
over center adjuster screw to obtain the proper
torque. Re-tighten the lock nut to the lock nut.
(6) After tightening the locknut, measure the over-
center drag torque again and readjust the torque, if
necessary.
INSTALL
(1) Align the installation reference marks and in-
stall the pitman arm.
(2) Install and tighten the pitman shaft nut and
washer to 251 Nzm (185 ft. lbs.) torque.
(3) Install the horn button.
GEAR DISASSEMBLY
(1) Rotate the wormshaft from stop-to-stop and
count the number of rotations. Rotate the wormshaft
in the reverse direction 1/2 of the total number of ro-
tations to center it and the ball nut.
(2) Remove the pitman shaft adjustment screw
locknut. Remove the cover retaining bolts, cover, and
gasket (Fig. 3).
(3) Slide the adjustment screw head (Fig. 3) out of
the pitman shaft T-slot and remove it and the
shim(s).
(4) Retain the shim(s) for end-play measurement
during assembly.
(5) Remove the pitman shaft, the wormshaft bear-
ing preload torque adjustment cap locknut, and the
adjustment cap (Fig. 2).
(6) Remove the wormshaft and the ball nut (Fig.
2).
(7) Remove (pry) the pitman shaft and the worm-
shaft seals from the steering gear housing (Fig. 3).
WORMSHAFT AND BALL NUT DISASSEMBLY
(1) Remove the upper bearing from the wormshaft
(Fig. 2).
CAUTION: Do not allow the ball nut to rotate freely
and travel to either extreme end of the wormshaft.
This could damage the tangs at the ends of the re-
circulating ball guides (Fig. 3).
(2) Remove the recirculating ball guide clamp re-
taining screws, the clamp and the guides (Fig. 2).
Separate the half-guides and place the recirculating
balls aside in a container.
