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 and
C20-30 series units have an adjustable tie rod connected
to the steering arm at each wheel. Steering effort is
LUBRICATION
The steering gear is filled at the factory with a water
resistant grease. Seasonal change of this lubricant is un­
necessary and the housing should not be drained. The
steering gear lubricant level should be checked every
36,000 miles. Whenever required, additions should be
made using a water resistant EP Chassis Lubricant.
If a filler plug is used on the steering gear, fill the
gear to the plug opening level. On models without a filler
plug, check and fill the steering gear as follows:
1. Remove lower and outboard cover retaining screws,
(fig. ).

2. Insert filling device in lower screw hole.
3. Inject lubricant until it appears in the outboard screw
hole (forward hole on Chevy Van); gear is now filled
to correct level.

to the pitman arm on the left and an idler arm on the

connecting the left and right steering arms. Steering
effort is relayed to the left steering arm, from the pit­
man arm, by a non-adjustable connecting rod.
