7. Clean the reservoir cover and gasket. Inspect the
O-ring and the cover for cracks, deformities, or
damage. Replace the gasket seal or cover as
needed.
8. Install the reservoir cover along with the spring
and the top plate. Make sure the center of the
top plate fits into the opening at the top of the
filter.
9. Place the clamp over the flanges of the cover
and shell assembly, then tighten 25 to 30 lbf·ft
(35 to 40 N·m).
10. Using ATF fluid that meets Dexron III or TES-389
specifications,, fill the power steering reservoir to
the FULL COLD mark.
11. Start the engine and operate it at idle. Turn the
steering wheel to full lock left and right to adjust
the fluid level and remove any existing air from
the power steering pump and gear. Recheck the
fluid level. Add fluid as needed. The system is
properly bled when the steering pump does not
labor when turning the wheel.
12. Check for leaks in the power steering system
and repair as needed. Top off the power steering
fluid level as needed.

Level Inspection
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2. With the engine cool, use a shop towel or a
clean rag to clean the area around the power
steering reservoir fill cap. Twist the cap counter-
clockwise to remove it. Check the cold power
steering fluid level. The level should be between
ADD COLD and FULL COLD with the engine off.
3. Start the engine and run it at idle until it reaches
operating temperature.
Remove the dipstick, and check that power
steering fluid is between ADD HOT and FULL
HOT. If necessary, add enough ATF fluid that
meets Dexron III or TES-389 specifications to
bring the level up to the FULL HOT mark on the
dipstick.
46–04 Power Steering Gear
Lubrication
Sheppard Steering Gears
Sheppard power steering gears manufactured with-
out grease fittings are maintenance-free. If the power
steering gear has no grease fitting, then it requires
no periodic lubrication.
Sheppard power steering gears with grease fittings
must be lubricated periodically.
1. Wipe off debris from the bearing cap grease fit-
ting. See
Fig. 1 .
2. Using a hand-type grease gun, apply multipur-
pose chassis grease until grease starts coming
out of the bearing cap dirt-and-water seal.
TRW Steering Gears
NOTICE
Apply grease to the sector shaft with a hand-type
grease gun only. Use of a high-pressure power
grease gun will supply grease too quickly and
could affect the high pressure seal, contaminating
the hydraulic fluid.
Using a hand-type grease gun, apply NLGI Grade 2
or 3 multipurpose chassis grease until it starts to
come out past the sector shaft seal. See
Fig. 2 .
