BOOT SEAL
DESCRIPTION
The boot seal is a bellows type seal the protects
dirt and contaminates from entering the open gears
of the rack and pinion unit.
OPERATION
The boot seal operates with the inward and out-
ward motions of the rack and pinion, If the seal is
worn or ripped in any way it must be replaced.
REMOVAL
(1) Loosen the jam nut to remove the outer tie rod
end,(Refer to 19 - STEERING/LINKAGE/TIE ROD
END - REMOVAL).
(2) Remove the jam nut.
(3) Remove the outer clamp from the rubber boot
(Fig. 4).
(4) Remove the boot inner clamp.
(5) On 4x2 vehicles mark the breather tube loca-
tion on steering gear before removing the rubber boot
(Fig. 4).
INSTALLATION
(1) Lubricate the boot outer groove (tie rod) with
silicone type lubricant. Ensure that the boot is not
twisted.
(2) On 4x2 vehicles align the breather tube with
the reference mark on the steering gear.
(3) Position and align the new boot over the hous-
ing.
(4) Install inner clamp on the rubber boot.
(5) Install the snorkel clamp on 4x2 vehicles.
(6) Install outer clamp on the inner tie rod.
(7) Install the jam nut and the outer tie rod
end,(Refer to 19 - STEERING/LINKAGE/TIE ROD
END - INSTALLATION).
(8) Perform a wheel alignment,(Refer to 2 - SUS-
PENSION/WHEEL
ALIGNMENT
-
STANDARD
PROCEDURE).

POWER STEERING PRESSURE SWITCH
PULLEY
PUMP
DESCRIPTION
The pump is connected to the steering gear via the
pressure hose and the return hose. The pump shaft
has a pressed-on pulley that is belt driven by the
crankshaft pulley.
Trailer tow option vehicles are equipped with a
power steering pump oil cooler. On the 5.2L and 5.9L
the oil cooler is mounted to the engine block. On the
4.7L the oil cooler is mounted to the power steering
pump.
NOTE: Power steering pumps are not interchange-
able with pumps installed on other vehicles.
OPERATION
Hydraulic pressure is provided for the power steer-
ing gear by the belt driven power steering pump (Fig.
1) and (Fig. 2). The power steering pumps are con-
stant flow rate and displacement, vane-type pumps.
DIAGNOSIS AND TESTING - PUMP LEAKAGE
The pump is serviced as an assembly and should
not be disassembled. Plastic pump reservoirs can be
replace and the reservoir O-ring.
Check for leaks in the following areas:
• Pump shaft seal behind the pulley
• Pump to reservoir O-ring
• Reservoir cap
• Pressure and return lines
• Flow control valve fitting

STANDARD PROCEDURE - POWER STEERING
PUMP - INITIAL OPERATION
WARNING:
THE
FLUID
LEVEL
SHOULD
BE
CHECKED WITH ENGINE OFF TO PREVENT INJURY
FROM MOVING COMPONENTS.
CAUTION: Use MOPAR Power Steering Fluid or
equivalent. Do not use automatic transmission fluid
and do not overfill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicate COLD when the fluid is
at normal temperature.
(1) Turn steering wheel all the way to the left
(2) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two (2) minutes.
(3) Raise the front wheels off the ground.
(4) Slowly turn the steering wheel lock-to-lock 20
times with the engine off while checking the fluid
level.
NOTE: Vehicles with long return lines or oil coolers
turn wheel 40 times.
(5) Start the engine. With the engine idling main-
tain the fluid level.
(6) Lower the front wheels and let the engine idle
for two minutes.
(7) Turn the steering wheel in both direction and
verify power assist and quiet operation of the pump.
If the fluid is extremely foamy or milky looking,
allow the vehicle to stand a few minutes and repeat
the procedure.
CAUTION: Do not run a vehicle with foamy fluid for
an extended period. This may cause pump damage.
