12. MAINTENANCE
The power steering system requires little
maintenance. However, the system should be
kept clean to ensure maximum operating
performance and troublefree service. Periodic
inspections should also be made to check for
leakage and all parts for damage or distortion.
Insure all fasteners are tight (see "14.
Specifications" for recommended tightening
torques.
When the slightest evidence of dirt, sludge or
water is discovered in the system, disconnect fluid
lines at the power steering gear to drain the
system. Drain and refill the system with "Dexron-
IIE or Dexron-III" automatic transmission oil.
Air in the hydraulic system will cause spongy
action and noisy operation. When a hose has
been disconnected or when fluid has been lost for
any reason, the system must be bled. Bleed
system as outlined under heading 3: "Bleeding
Power Steering Hydraulic System".
CAUTION
Do not operate the pump without fluid in the
power steering fluid reservoir.
If the steering linkage between the steering gear
and the two front wheels is not properly adjusted,
or if it is bent, twisted or worn, the steering of the
vehicle will be seriously impaired. Whenever a
steering linkage part is repaired, replaced or
adjusted, steering geometry and front wheel
alignment must be checked and necessary
corrections made. Refer to section 10 "Front
Axle" under heading 6: "Front Wheel Alignment".
At regular lubrication intervals, the steering
linkage should be thoroughly inspected for worn
or loose components.
After the vehicle has been operated continually
and high mileage figures have been reached,
overhaul of the various steering units will be
required. General overhaul procedure normally
requires removal of the entire assembly, cleaning
and inspection of all parts and final assembly.
Careful inspection of all parts during overhaul is
very important and must not be neglected.
Lubrication fittings must all be cleaned before
applying lubricant. Moreover, always be sure the
equipment used in applying lubricant is clean.
Every precaution should be taken to prevent entry
of dirt, grit, lint or other foreign matter into
lubricant containers. Replace fittings that have
become broken or damaged. Lubrication
intervals, as well as the recommended lubricants
for the steering components, are given in the
"Lubrication And Servicing Schedule" in Section
24 of this manual. The intervals given in the
schedule are recommended for normal service.
More frequent intervals may be required under
severe operating conditions.
12.1 POWER STEERING RESERVOIR AND
FILTER
