LINKAGE
DESCRIPTION
The steering linkage consists of a pitman arm,
drag link, tie rod, and steering dampener (Fig. 1).
Adjustment sleeves are used on the tie rod and drag
link for toe and steering wheel alignment.
The service procedures and torque specifications
are the same for LHD and RHD vehicles.
STANDARD PROCEDURE
STANDARD PROCEDURE - LUBRICATION
Periodic lubrication of the steering system compo-
nents is required. Refer to Lubrication And Mainte-
nance for the recommended maintenance schedule.
The following components must be lubricated:
• Tie rod ends
• Drag link
STANDARD PROCEDURE - STEERING LINKAGE
The tie rod end and ball stud seals should be
inspected during all oil changes. If a seal is damaged,
it should be replaced. Before installing a new seal,
inspect ball stud at the throat opening. Check for
lubricant loss, contamination, ball stud wear or cor-
rosion. If these conditions exist, replace the tie rod. A
replacement seal can be installed if lubricant is in
good condition. Otherwise, a complete replacement
ball stud end should be installed.
CAUTION: If any steering components are replaced
or serviced an alignment must be performed, to
ensure the vehicle meets all alignment specifica-
tions.
CAUTION: Components attached with a nut and cot-
ter pin must be torqued to specification. Then if the
slot in the nut does not line up with the cotter pin
hole, tighten nut until it is aligned. Never loosen the
nut to align the cotter pin hole.

PUMP
DESCRIPTION
Hydraulic pressure for the power steering system
is provided by a belt driven power steering pump
(Fig. 1). The pump shaft has a pressed-on high
strength plastic drive pulley that is belt driven by
the crankshaft pulley. The reservoir is attached to
the pump body with spring clips on the 4.0L engine.
A remote pump reservoir is used on the 2.4L engine
mounted to the fan shroud. The power steering pump
is connected to the steering gear by the pressure and
return hoses.
OPERATION
The power steering pump is a constant flow rate
and displacement, vane-type pump. The pump inter-
nal parts operate submerged in fluid. The flow con-
trol orifice is part of the high pressure line fitting.
The pressure relief valve inside the flow control valve
limits the pump pressure.
NOTE: Power steering pumps have different pres-
sure rates and are not interchangeable with other
pumps.
DIAGNOSIS AND TESTING - PUMP LEAKAGE
(1) Possible areas of pump leakage (Fig. 2).
STANDARD PROCEDURE - POWER STEERING
PUMP - INITIAL OPERATION
WARNING:
THE
FLUID
LEVEL
SHOULD
BE
CHECKED WITH ENGINE OFF TO PREVENT INJURY
FROM MOVING COMPONENTS.
CAUTION: MOPAR
T
ATF+4 is to be used in the
power steering system. No other power steering or
automatic transmission fluid is to be used in the
system. Damage may result to the power steering
pump and system if any other fluid is used, and do
not overfill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicate COLD when the fluid is
at normal ambient temperature.
(1) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two minutes.
(2) Start the engine and let run for a few seconds
then turn engine off.
