WHEELS (RIMS)
WARNING: Mounting a regular tire on a high-pressure compact spare
wheel is not permitted. Attempting to mount a tire of one
diameter on a wheel of a different diameter or flange
type may result in serious injury or death. If the wheel
identification stamp is not legible, or cannot be found,
do not use the wheel until the size and type have been
properly identified. Wheels of different diameter,
offset, or width cannot be mixed on the same axle. Bead
seat tapers cannot be interchanged.

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 .
