9 - 2 4 STEERING
M A IN TEN A N C E A N D ADJUSTMENTS
LUBRICATION
The manual steering gear is factory-filled with steering
gear lubricant. Seasonal change of this lubricant should
not be performed and the housing should not be drained
- no lubrication is required for the life of the steering
gear.
Every 36,000 miles, the manual gear should be inspected
for seal leakage
(actual solid grease - not just oily film).
If a seal is replaced or the gear is overhauled, the gear
housing should be refilled with #1051052 (13 oz.
container) Steering Gear Lubricant which meets GM
Specification GM 4673M, or its equivalent.
NOTE: Do not use EP Chassis Lube, which
meets GM Specification GM 6031M, to
lubricate the gear. DO NOT OVER-FILL the
gear housing.
The steering linkage under normal conditions should be
lubricated with any water resistant EP type chassis
lubricant every 6,000 miles or four months, whichever
occurs first. Lubricate every 3,000 miles or two months
whichever occurs first when operating in dusty or muddy
conditions or if the vehicle is used "off-road".
Lubrication points and additional information on the
chassis lubricant recommended can be found in Section
0-G eneral Information and lubrication.

Before any adjustments are made to the steering gear
attempt to correct complaints of loose or hard steering,
or other wheel disturbances, a careful check should be
made of front end alignment, shock absorbers, wheel
balance and tire pressure for possible steering system
problems. See Diagnosis in sections 3 and 9.
Correct adjustment of steering gear is very important.
While there are but two adjustments to be made, the
following procedure must be followed step-by-step in the
order given.
1. Disconnect the battery ground cable.
2. Raise the vehicle.
3. Remove the pitman arm nut. Mark the relationship
of the pitman arm to the pitman shaft. Remove the
pitman arm with Tool J-6632 or J-5504 as shown in
Figure 45.
4. Loosen the steering gear adjuster plug locknut and
back the adjuster plug off 1/4 turn (fig. 33).
5. Remove the horn shroud or button cap.
6. Turn the steering wheel gently in one direction until
stopped by the gear; then turn back one-half turn.
CAUTIO N:
Do not turn the steering wheel hard
against the stops when the steering linkage is
disconnected from the gear as damage to the
ball guides could result.
7. Measure and record "bearing drag" by applying a
torque wrench with a socket on the steering wheel
nut and rotating through a 90° arc (fig. 34).
NOTE: Do not use a torque wrench having a
maximum torque reading of more than 50
inch pounds.
8. Adjust “thrust bearing preload” by tightening the
adjuster plug until the proper “thrust loading
preload” is obtained (See specifications section at
rear of this manual). When the proper preload has
been obtained, tighten the adjuster plug locknut to
specifications and recheck torque. If the gear feels
“lumpy” after adjustment, there is probably
damage in the bearings due to severe impact or
improper adjustment; the gear must be disassem
bled and inspected for replacement of damaged
parts.
9. Adjust “over-center preload” as follows:
a. Turn the steering wheel gently from one stop all
the way to the other carefully counting the total
number of turns. Turn the wheel back exactly
half-way, to center position.
b. Turn the lash adjuster screw clockwise to take
out all lash between the ball nut and pitman
shaft sector teeth and then tighten the locknut.
c. Check the torque at the steering wheel, taking
