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 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.
