1998 MITSUBISHI MONTERO lock

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.

ADJUSTMENTS & INSPECTION
WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES
NOTE: See WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES article in
WHEEL ALIGNMENT section.
WHEEL BEARING
Preload
1) Using Socket (MB990954) and torque wrench, tighten axle
lock nut to 119 ft. lbs. (162 N.m) on Montero, 94-145 ft. lbs. (127-
196 N.m) on Montero Sport. Loosen nut to 0 ft. lbs. (0 N.m). Retighte\
n
nut to 18 ft. lbs. (25 N.m).
2) Loosen nut 30-40 degrees on Montero, 30 degrees on Montero
Sport. Install lock washer. If lock washer hole is not aligned with
lock nut hole, lock nut may be rotated up to 20 degrees to obtain
alignment. After setting preload, check hub turning resistance and
axial play (4WD only).
Hub Turning Resistance & Axial Play (4WD Only)
1) Using dial indicator, check front hub axial play. Axial
play should be 0.002" (0.05 mm) or less. Using INCH-lb. torque wrench
or spring scale attached to wheel stud, measure hub turning
resistance. Turning resistance should be 1.1-4.0 lbs. (5-18 N) on
Montero or 0.9-4.3 lbs. (4-19 N) on Montero Sport if measured using
spring scale, or 2.6-11.3 INCH lbs. (0.3-1.3 N.m) on both models if
measured using torque wrench.
2) Adjust wheel bearing so turning resistance and axial play
are within specification. If turning resistance and axial play cannot
be adjusted to specification, check wheel bearing condition and
installation.
Drive Axle End Play (4WD Only)
Install drive axle shim and snap ring. Push drive shaft in
toward knuckle. Measure clearance between drive flange and shim with a
feeler gauge. If clearance is not 0.016-0.028" (0.4-0.7 mm) replace
shim to bring clearance into specification.
BALL JOINT CHECKING
Lower Ball Joint
Place ball joint in soft-jawed vise. Install dial indicator
with stem resting on end of ball joint stud. Measure ball joint stud
end play. Replace ball joint if end play exceeds 0.012" (0.3 mm). For
ball joint replacement, see LOWER BALL JOINT under
REMOVAL & INSTALLATION .
Upper Ball Joint
1) Disconnect ball joint from steering knuckle. Place nut on
ball joint stud. Using INCH-lb. torque wrench, measure starting torque
required to rotate ball joint stud.
2) Starting torque should be 7-30 INCH lbs. (0.8-3.5 N.m).
Replace ball joint if starting torque is not within specification. For
ball joint replacement, see UPPER BALL JOINT under
REMOVAL & INSTALLATION .
