( 1) - Approximate quantity listed.
( 2) - Use an API energy conserving engine oil that is certified for
gasoline engines.
( 3) - Add this amount of fluid. Start engine and shift transmission
through all gears and back to Neutral. Add additional fluid to
bring fluid level to the MIN mark on dipstick. Recheck fluid
level with transmission at normal operating temperature. Adjust
fluid level to MAX mark on dipstick. Approximate drain and
refill capacity is 4.0 qts. (3.8L).
( 4) - Quantity may vary by type of oil cooler and oil cooler lines.
( 5) - Use only Mopar power steering fluid. DO NOT use automatic
transmission fluid.
( 6) - Rear differential may be identified by full-floating axles
shafts.
( 7) - Models with Trac-Lok limited slip differential must have 6 ozs.
(.18L) of Mopar Trac-Lok Friction Modifier added if lubricant is\

1998-99 STEERING
CHRY - Power Recirculating Ball - RWD Trucks
Dakota 4WD, Ram Pickup, Ram Van/Wagon
DESCRIPTION & OPERATION
The recirculating ball power steering system consists of
steering gear, steering linkage, pressure and return fluid hoses and
fittings, and a hydraulic steering pump with fluid reservoir.
The steering gear is a power assisted recirculating-ball type
that acts as a rolling thread between worm shaft and rack piston. See
Fig. 1 . When worm shaft is turned, the rack piston moves and piston
teeth mesh with sector shaft teeth, turning pitman arm, which turns
steering linkage.
The steering linkage consists of pitman arm, idler arm(s),
tie rods, center link and drag link (if equipped).
The power steering pump is a constant flow rate and
displacement, vane-type pump. Pump is connected to steering gear by
pressure and return hoses. On gasoline models, pump shaft has pressed
on belt-driven pulley.
On diesel models, power steering pump is bolted onto rear of
vacuum pump and is driven by a common shaft.

TESTING
Page 1247 of 1691
NOTE: Before testing, check fluid level, belt tension, pump pulley,
tire pressure and engine idle speed.
HYDRAULIC SYSTEM PRESSURE TEST
NOTE: Replacement fittings are required on Pressure Test Gauge(C
-3309E) for adapting to "O" ring type hose tube ends.
Idle Pressure Test
1) Remove high pressure hose at steering pump and connect a
spare hose to pump fitting. Connect opposite end of spare hose to
Pressure Test Gauge (C-3309E). Connect pressure hose from valve side
of steering gear to valve side of gauge. Valve must be installed on
outlet side of gauge. See Fig. 2.
2) Fully open shutoff valve on test gauge. With a thermometer
in fluid reservoir, start engine and warm fluid to 150-170
F (66-
77 C). Turning wheels from stop-to-stop will aid in warming fluid. DO
NOT hold wheels against stop.
3) With engine at idle and gauge valve open, check initial
pressure. See POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS table.
If pressure is greater than 125 psi (8.8 kg/cm
), check for restricted
hoses or crimped lines.

\
\
\
\
\
\

CAUTION: DO NOT leave shutoff valve closed more than 5 seconds, or
pump damage could result.
Page 1248 of 1691
Relief Pressure Test
1) Close gauge shutoff valve completely 3 times. Record
highest pressure attained each time. All 3 readings must be greater
than specifications and within 50 psi (3.5 kg/cm
) of each other. See
POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS table. If pressures
are not as specified, replace pump. See POWER STEERING PUMP (GASOLINE)\
or VACUUM/POWER STEERING PUMP (DIESEL) under REMOVAL & INSTALLATION.
CAUTION: DO NOT hold steering wheel against stops more than 4 seconds,
or pump damage may result.
2) Open test valve and turn steering wheel to left and right
stops. Record highest pressure attained at each stop. If output
pressures are not equal against each stop, gear is leaking internally
and must be replaced. See STEERING GEAR under REMOVAL & INSTALLATION.
Shut off engine, remove test gauge, and connect pressure hose.

FLUID TYPE
CAUTION: DO NOT use Automatic Transmission Fluid (ATF).
Use Mopar Power Steering Fluid (4318055).
FLUID LEVEL CHECK
Check fluid level with engine cold and not running. Remove
fluid level dipstick on pump reservoir. Dipstick should indicate FULL
COLD with fluid temperature of 70-80
F (21-27 C). If needed, add fluid
through dipstick opening, and recheck. DO NOT overfill.
HYDRAULIC SYSTEM BLEEDING
Fill power steering pump reservoir to specified level. Start
engine and slowly turn steering wheel to left and right, but DO NOT
contact steering stops in either direction. Stop engine. Inspect
reservoir fluid level and add fluid if necessary. Bleeding process may
have to be repeated several times to completely purge all air from
system.
ADJUSTMENTS
POWER STEERING PUMP BELT
Vehicles are equipped with dynamic tensioner. No adjustment
is required.
POWER STEERING PUMP PULLEY
Page 1249 of 1691
After pulley installation, run the engine until warm. See
PUMP PULLEY under REMOVAL & INSTALLATION. If drive belt chirps, move
pulley outward approximately .020" (0.5 mm). If noise increases, press\
pulley inward .040" (1.0 mm). Ensure pulley does not contact mounting
bolts.
THRUST BEARING PRELOAD
NOTE: Manufacturer recommends removing steering gear from vehicle
before performing any adjustments.
1) Remove steering gear from vehicle. See STEERING GEAR under
REMOVAL & INSTALLATION. Ensure steering gear is empty of hydraulic
fluid. Rotate steering from stop-to-stop several times to drain fluid.
Loosen lock nut on adjuster plug. See Fig. 3. Using spanner wrench,
rotate adjuster plug clockwise until plug is seated in housing. Torque
will be approximately 20 ft. lbs. (27 N.m).

2) Place reference mark on steering gear housing adjacent to
one hole in adjuster plug. Measure counterclockwise about 1/2" (13 mm)\
Page 1251 of 1691
REMOVAL & INSTALLATION
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
the COMPUTER RELEARN PROCEDURES article in GENERAL
INFORMATION before disconnecting battery.
POWER STEERING PUMP (GASOLINE)
WARNING: DO NOT attempt to remove power steering pump without removing
power steering pump belt. Personal injury or pulley damage
could result.
Removal
1) Disconnect and isolate negative battery cable. To remove
serpentine belt, rotate tensioner clockwise and hold in place, slide
belt from tensioner pulley. Place drain pan under pump. Disconnect and
cap hoses.
2) Remove bracket-to-engine block bolts. Remove pump, pulley
and mounting bracket as an assembly. To allow access to pump screws,
remove pump pulley. See PUMP PULLEY. Remove bracket-to-pump screws.
Installation
To install pump, reverse removal procedure. Fill and bleed
system. See HYDRAULIC SYSTEM BLEEDING under LUBRICATION.
VACUUM/POWER STEERING PUMP (DIESEL)
Removal
1) Disconnect negative battery cable. Place drip pan under
vacuum/power steering pump. Disconnect and cap power brake booster
hose at vacuum pump and hydraulic lines at power steering pump.
Disconnect oil pressure sending unit electrical connector. Remove
sending unit from engine block and plug hole in block. Disconnect and
cap oil feed line from bottom of vacuum pump.
2) Remove vacuum/power steering pump-to-engine block nuts and
bolts, and mounting bracket. Remove upper pump bolt and remove pump.
Drain fluid from steering pump reservoir. Remove gaskets from mounting
surfaces.
CAUTION: DO NOT damage internal vacuum pump oil seal when separating
steering pump from vacuum pump. See Fig. 5.
3) Remove steering pump-to-vacuum pump bracket bolts.
Carefully slide steering pump from bracket. Remove 2 pump body
spacers. See Fig. 5.
NOTE: Steering pump housing and spacers must mate completely with
vacuum pump bracket.
Installation
1) Install 2 pump body spacers and rotate drive gear until
steering pump and vacuum pump drive splines align. See Fig. 5.
Carefully install steering pump on vacuum pump bracket to prevent
damaging oil seal.
