Lubrication
Wipe the grease fittings clean. Using a pressure gun,
apply a lithium-based grease (NLGI grade 2) spar-
ingly to the universal joints and slip-joint splines.
46–02 Drag Link Lubrication
1.
Using a clean rag, wipe the dirt from the grease
fitting on the drag link.
2.
Using a pressure gun, apply multipurpose chas-
sis grease at the grease fitting until old grease is
forced out of the socket.
NOTE: Use multipurpose chassis grease NLGI
grade 1 (6% 12-hydroxy lithium stearate grease)
or NLGI grade 2 (8% 12-hydroxy lithium stear-
ate grease). The grade 2 chassis grease is pre-
ferred.
46–03 Power Steering
Reservoir Fluid Level
Check
1.
Turn the engine OFF.
2.
Check the fluid level in the power steering reser-
voir.
•
Use the COLD markings on the dipstick if
the engine is at room temperature, 70°F
(20°C).
•
Use the HOT markings on the dipstick if
the engine is at normal operating tempera-
tures, 175°F (80°C).
3.
The fluid level must show between the ADD and
FULL markings on the dipstick. If the fluid level is
below the ADD mark, add Motorcraft MERCON
®
ATF XT-2-WDX or MERCON
®
equivalent.
NOTE: After any major power steering system
or component overhaul, the system should be
purged of old fluid and the filter discarded. New
fluid and a new filter should be installed.
46–04 Power Steering
Reservoir Fluid and
Filter Change
1.
Using a suction gun, remove fluid from the reser-
voir through the filler opening or remove the re-
turn hose to drain the reservoir
2.
Remove the cover from the reservoir by remov-
ing the clamp.
3.
Take out the spring, filter cap and filter.
4.
Thoroughly clean the reservoir with a lint-free
cloth.
5.
Install the replacement filter, filter cap and spring.
6.
Install the gasket, cover, and clamp.
7.
Fill the reservoir to the cold mark with Motorcraft
MERCON
®
ATF XT-2-QDX or MERCON
®
equiva-
lent.
WARNING
Fill only with approved clean fluid. Do not mix
fluid types. Any mixture or any unapproved fluid
could lead to seal deterioration and leaks. Fluid
leakage could cause loss of power steering assist.
8.
Place the front wheels in straight-ahead position
and engage the parking brake. Do not turn the
steering wheel during the initial fill procedure.
9.
Fill the reservoir with fluid and allow the fluid to
gravity feed the system. Crack the pressure line
fittings at the pump and steering gear. Tighten
the fittings when fluid is visible. Keep adding fluid
to the reservoir as required.
10. Start the engine and let it idle. Turn the steering
wheel from lock to lock until no bubbles are seen
in the reservoir. Turn off the engine.
11. When the fluid level in the reservoir no longer
goes down, start the engine. Continue to add
fluid to the reservoir as required. Do not exceed
the FULL mark.
12. Continue the process until the fluid level no
longer changes. The fluid level is correct when it
is in the full range on the dipstick.
