1991 WHEEL ALIGNMENT
Specifications & Procedures
Chrysler Motors: Colt, Colt Vista, Colt 200,
Ram-50, Stealth, Summit
Mitsubishi: Eclipse, Galant, Mirage, Montero,
Pickup, Precis, 3000GT
WHEEL ALIGNMENT PROCEDURES
NOTE: On vehicles with electronic chassis controls, ensure all
systems are functional before attempting to adjust riding
height or wheel alignment.
CAMBER ADJUSTMENT
Montero, Pickup & Ram-50
1) Check tire inflation. Place front wheel on turning radius
gauge, and level vehicle (unladed). On 2WD models, remove hub cap and
cotter pin. On 4WD models, remove free wheeling hub assembly.
2) On all models, measure camber with camber/caster/kingpin
gauge attached. See appropriate WHEEL ALIGNMENT SPECIFICATIONS table.
If camber is not within specification, remove shock absorber mounting
nut and lock nut.
3) Compress shock absorber and loosen upper arm mounting
bolts and nuts. Adjust camber by increasing or decreasing shims
between upper arm shaft and crossmember. See Fig. 1.
CAUTION: Difference in shim thickness between front and rear must be
.16" (4 mm) or less. DO NOT use more than 3 shims at one
location.

Stealth & 3000GT
Page 1300 of 1333
Check camber. If camber is not within specification, loosen
eccentric cam nut. Rotate eccentric cam bolt to obtain correct camber.
See Fig. 2 . Each marking represents a change of 1/8-1/4 degree of
camber.

All Other Models
Check camber using a camber/caster/kingpin gauge and turning
radius gauge. See WHEEL ALIGNMENT SPECIFICATIONS table. If camber is
not within specification, replace damaged or bent parts.
CASTER ADJUSTMENT
Colt Vista
Check tire inflation. Place front wheel on turning radius
gauge, and level vehicle (unladed). Remove hub cap and cotter pin.
Measure caster with camber/caster/kingpin gauge attached. See WHEEL
ALIGNMENT SPECIFICATIONS table. If caster is not within specification,
adjust by changing strut bar lock position. See Fig. 3.

Montero
Page 1301 of 1333
Remove free wheeling hub. Measure caster with
camber/caster/kingpin gauge and turning radius gauge. See WHEEL
ALIGNMENT SPECIFICATIONS table. If caster is not within specification,
remove upper arm from crossmember. Adjust caster by turning upper arm
shaft. See Fig. 4.

Pickup & Ram-50
1) Check tire inflation. Place front wheel on turning radius
gauge, and level vehicle (unladed). On 2WD models, remove hub cap and
cotter pin. On 4WD models, remove free wheeling hub assembly.
2) On all models, measure caster with camber/caster/kingpin
gauge attached. See WHEEL ALIGNMENT SPECIFICATIONS table. If caster is
not within specification, remove shock absorber mounting nut and lock
nut.
3) Compress shock absorber and loosen upper arm mounting
bolts and nuts. Adjust caster by increasing or decreasing shims
between upper arm shaft and crossmember. See Fig. 1.
CAUTION: Difference in shim thickness between front and rear must be
.16" (4 mm) or less. DO NOT use more than 3 shims at one
location.
All Other Models
Check caster using a camber/caster/kingpin gauge and turning
radius gauge. See WHEEL ALIGNMENT SPECIFICATIONS table. If caster is
not to specification, replace damaged or bent parts.
TOE-IN ADJUSTMENT
Check toe-in. See WHEEL ALIGNMENT SPECIFICATIONS table. If
Page 1302 of 1333
toe-in is not within specification, remove clips. Turn tie rods or
turnbuckles the same amount, but in opposite directions. Recheck toe-
in.

GENERAL INFORMATION
Wheel Alignment Theory & Operation
ALL MODELS
* PLEASE READ THIS FIRST *
NOTE: This article is intended for general information purposes
only. This information may not apply to all makes and models.
PRE-ALIGNMENT INSTRUCTIONS
GENERAL ALIGNMENT CHECKS
Before adjusting wheel alignment, check the following:
* Each axle uses tires of same construction and tread style,
equal in tread wear and overall diameter. Verify that radial
and axial runout is not excessive. Inflation should be at
manufacturer's specifications.
* Steering linkage and suspension must not have excessive play.
Check for wear in tie rod ends and ball joints. Springs must
not be sagging. Control arm and strut rod bushings must not
have excessive play. See Fig. 1.
Fig. 1: Checking Steering Linkage
* Vehicle must be on level floor with full fuel tank, no
passenger load, spare tire in place and no load in trunk.
Bounce front and rear end of vehicle several times. Confirm
