The steering gear used on all truck models is of the
recirculating ball type and the service procedures are
basically the same for all units.
Two types of steering linkages are used. C-P10-20-30
series units have an adjustable tie rod connected to the
steering arm at each wheel. Steering effort is trans­
LUBRICATION
The 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 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.
Do not use EP Chassis Lube, which
NOTE:
meets GM Specification GM 6031M, to lubricate
the gear. DO NOT OVER-FILL the gear housing.

NOTE:
ing wheel to steering shaft and all steering link­
age fasteners are important attaching parts in
that they could affect the performance of vital
components and systems, and/or could result in
major repair expense. They must be replaced
with one of the same part number or with an
equivalent part if replacement becomes nec­
essary. Do not use a replacement part of lesser
quality or substitute design. Torque values must
be used as specified during reassembly to assure
proper retention of this part.
