DRIVE AXLE - NOISE DIAGNOSIS
Unrelated Noises
Some driveline trouble symptoms are also common to the
engine, transmission, wheel bearings, tires, and other parts of the
vehicle. Ensure cause of trouble actually is in the drive axle before
adjusting, repairing, or replacing any of its parts.
Non-Drive Axle Noises
A few conditions can sound just like drive axle noise and
have to be considered in pre-diagnosis. The 4 most common noises are
exhaust, tires, CV/universal joints and wheel trim rings.

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

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
