STEERING SYSTEM - POWER RECIRCULATING BALL
1998 Mitsubishi Montero
1997-98 STEERING
Mitsubishi - Power Recirculating Ball
Montero, Montero Sport
DESCRIPTION & OPERATION
STEERING GEAR
The power steering gear displaces fluid to provide hydraulic
pressure assist while turning. A one-piece rack piston nut is geared
to cross shaft. Backlash is adjusted with an adjusting screw.
STEERING LINKAGE
Linkage consists of an idler arm, relay rod, steering
knuckles and adjustable tie rods. Components are connected by ball
joints. Linkage assembly is connected to steering gear by pitman arm.
LUBRICATION
FLUID TYPE
Recommended fluid type is Dexron-II ATF.
FLUID LEVEL CHECK
Place vehicle in level position. Start engine and let idle.
Turn steering wheel left and right. Replace fluid if it has bubbles or
has become White. Fluid level should be between MIN and MAX marks on
dipstick. Fill to proper level.
FLUID REPLACEMENT
CAUTION: DO NOT crank engine for more than 15-20 seconds at a time.
1) Remove reservoir cap. Disconnect return hose at reservoir.
Drain fluid. Disconnect coil high tension wire. Raise and support
vehicle.
2) Turn steering wheel lock-to-lock several times while
cranking engine to drain fluid from steering gear. Reconnect hose.
Fill power steering system with fluid. Bleed system. See
HYDRAULIC SYSTEM BLEEDING .
HYDRAULIC SYSTEM BLEEDING
CAUTION: DO NOT crank engine for more than 15-20 seconds at a time.
Add fluid as needed during procedure to prevent reservoir
level from dropping.
1) Ensure reservoir is filled before bleeding. Add fluid (if
necessary) during bleeding. Raise and support front of vehicle.
Disconnect coil high tension wire.
2) While cranking engine, turn steering wheel lock-to-lock 5
or 6 times. Lower vehicle. Connect coil wire. Start engine and let
idle. Turn steering wheel lock-to-lock until no more bubbles appear in
oil reservoir.

damage. Inspect groove of rotor vane and cam surface for stepped wear.
Check vane for damage. Install vane into rotor groove. Measure
clearance between vane and rotor groove. If clearance exceeds .0024"
(.061 mm), replace entire assembly.
2) Check ring and rotor sides for damage. Replace entire
assembly if any damage is present. Check sliding surfaces of control
valve for obstructions. Replace parts as required. If control valve is
replaced, always use valve with same identification mark as one being
replaced. Check power steering fluid pressure.
Reassembly
1) Lubricate "O" rings and internal pump components with ATF
before reassembly. Install flow control valve spring and control valve
in housing.
2) Install and tighten pressure connector. Depress control
valve to check for smooth operation. Apply grease to lip of oil seal.
Install oil seal into pump body. Install pulley assembly into pump
body.
3) Install rotor to pulley assembly with punch mark at pump
cover side. Install snap ring. Lift rotor to ensure that snap ring is
in countersunk part of shaft. Align cam ring dowel holes and install
cam ring with punch mark on pump body side.
4) Apply transmission fluid to vanes, and install vanes onto
rotor with rounded edges outward. Install "O" ring, cam case and pump
cover. Install and tighten suction connector.

DRAINING & REFILLING
NOTE: Although manufacturer recommends changing only fluid, the
oil filter/screen may also require replacement. If replacing
oil filter/screen, note length and location of all bolts.
Transaxle (Except Montero)
1) Remove drain plug(s), and drain fluid. Some models may
contain a drain plug located in housing below axle shaft, in oil pan.
Remove oil pan. Remove oil filter/screen if necessary.
2) If oil filter/screen is replaced, tighten bolts to
specification. See TORQUE SPECIFICATIONS . Clean oil pan, replace
gasket, and install oil pan. Tighten oil pan bolts and drain plug to
specification. See TORQUE SPECIFICATIONS . Ensure dipstick hole area is
clean. Fill transmission with Diamond ATF SP-II, through filler tube,
until COLD level is reached on dipstick.
3) Start engine and allow to idle for 2 minutes. Shift
transaxle to each position, ending in Neutral. Add sufficient fluid to
reach lower mark. After reaching normal operating temperature, fluid
should be between upper and lower marks of HOT range on dipstick.
Transmission (Montero)
1) Remove drain plug (if equipped) from transmission pan, an\
d
allow fluid to drain. On models without drain plug, oil pan must be

removed to drain fluid. Remove oil filter/screen if necessary.
2) If oil filter/screen is replaced, tighten bolts to
specification. See TORQUE SPECIFICATIONS . Clean oil pan, replace
gasket, and install oil pan. Tighten oil pan bolts and drain plug to
specification. See TORQUE SPECIFICATIONS . Ensure dipstick hole area is
clean. Fill transmission with Dexron-II ATF, through filler tube,
until COLD level is reached on dipstick. Start engine, and allow to
idle for 2 minutes.
3) Shift transmission into each position, ending in Neutral.
Check fluid level with engine running at idle. If necessary, add
sufficient fluid to bring level to lower mark of dipstick. Recheck
fluid level after transmission is at normal operating temperature.
Transfer Case
Drain plug is located on bottom of transfer case. Change
drain plug gasket whenever fluid is changed. Lubricant level should be
at bottom of fill hole on side of transfer case.
ADJUSTMENTS
KICKDOWN SERVO
Eclipse, Galant & 3000 GT
1) Remove all dirt and grease around kickdown servo switch.
Remove snap ring and kickdown servo switch.
2) To prevent servo piston from turning, install Adapter
(MD998915) and Kickdown Servo Wrench (MD998918) so tab of wrench
engages with notch of piston. See Fig. 1.
CAUTION: DO NOT push servo piston inward while installing adapter and
servo wrench. Install adapter in brake pressure port by hand
ONLY. DO NOT use wrench to tighten adapter.
