WHEEL ALIGNMENT
WHEEL ALIGNMENT
Wheel alignment is defined as the measurement, analysis, and
adjustment of steering and suspension angles to conform to OEM
specifications. These angles usually include, but are not limited to:
caster, camber, toe, and thrust angle. Where these angles are not
adjustable and not in specification, component replacement or
correction kits may be required. Errors in set-back and steering axis
inclination (SAI) are often attributable to failed or damaged
components and must be corrected prior to performing an alignment.
Failure to replace or correct suggested parts or service may
prevent a proper alignment.
Before performing an alignment check, inspect and verify the
following:
* Tire pressure and size
* Vehicle loading
* Ride height
* Steering and suspension parts
If the inspection reveals that all the above are within
published specifications, a wheel alignment check and an alignment, if
needed, may be performed.
CAUTION: Under no circumstances should a technician bend or heat
any steering or suspension component, unless specified by
the vehicle manufacturer, for example, Ford forged twin
"I" beam axles. All measurements and specifications must
be noted on the inspection report.

WHEELS AND TIRES
TIRES
These guidelines do not apply to split rims. Some vehicle
manufacturers restrict replacement of tires to specific brands, types,
or sizes.
WARNING: High pressure temporary compact spare tires should not be
used with any other rims or wheels, nor should standard
tires, snow tires, wheel covers, or trim rings be used
with high pressure compact spare rims or wheels.
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.
WARNING: Only specially trained persons should dismount or mount
tires. Explosions of tire and wheel assembly can result
from improper mounting, possibly causing serious injury
or death.
WARNING: Consult the vehicle owner's manual or vehicle placard for
correct size, speed rating, designation, and cold
inflation pressure of the original tires. DO NOT exceed
the maximum load or inflation capacity of the tire
specified by the Tire and Rim Association
WARNING: When replacing tires, it is suggested that the
replacement tires match or exceed the OEM speed rating
designation. If tires of different speed rating
designations are mixed on the same vehicle, the tires may
vary in handling characteristics. DO NOT mix different
speed rating designations on the same axle.
WARNING: DO NOT mix radials with non-radial tires on the same
axle, as this may affect vehicle handling and stability.
If radial tires and bias or bias-belted ply tires are
mixed on the same vehicle, the radials must be on the
rear. High-pressure temporary compact spare tires are
exempt from this rule.
WARNING: DO NOT mix size or type (all season, performance, mud and
snow) of tires on the same axle.

SUN ROOF - POWER
1998 Mitsubishi Montero
1998 ACCESSORIES & EQUIPMENT
Mitsubishi - Power Sun Roofs
Eclipse, Galant, Montero, Montero Sport, 3000GT
DESCRIPTION & OPERATION
Sun roof is actuated by an overhead console-mounted switch.
Sun roof motor, located near switch, moves sun roof panel by means of
drive cables. If necessary, sun roof can be closed manually using
manual closure wrench stored in vehicle's tool pouch.
On vehicles equipped with Electronic Timer Alarm Control
System (ETACS) ECU, sun roof can be operated up to 30 seconds after
ignition switch is turned to OFF position.
Sun roof motor incorporates a safety feature that initially
limits opening or closing of roof glass panel. Sun roof will not fully
close from fully open position without first releasing and then
depressing slide switch during operation. Sun roof initially stops
about 8" short of fully closed position.

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 .
