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.

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.

NOTE: Prior to performing wheel alignment, perform visual and
mechanical inspection of wheels, tires and suspension
components. See PRE-ALIGNMENT INSTRUCTIONS in WHEEL ALIGNMENT
THEORY & OPERATION article in GENERAL INFORMATION.
RIDING HEIGHT ADJUSTMENT
CHECKING PROCEDURE
NOTE: Information on vehicles not listed was not available from
manufacturer.
1999 Caravan, Town & Country, & Voyager
Before adjusting alignment, check riding height. Measure
height from inboard edge of fenderwell directly above center of wheel,
unless specified otherwise. Riding height must be checked with vehicle
on level floor, correct size tires properly inflated and fuel tank
full. Bounce vehicle several times and allow suspension to settle.
Visually inspect vehicle for signs of abnormal height from
front-to-rear and side-to-side. Check passenger and luggage
compartments for extra-heavy items and remove if present. Riding
height between left side and right side of vehicle should vary less
than 0.5 (12.7 mm). Information on riding height between front and
rear is not available from manufacturer. See RIDING HEIGHT
SPECIFICATIONS (1999 CARAVAN, TOWN & COUNTRY, & VOYAGER) table. If
riding height is not within specification, check, repair or replace
suspension components.
Dakota & Durango (4WD)
1) Measure and record distance between floor surface and
center of lower suspension arm rear mounting bolt head. Measure and
record distance between floor surface and center of front wheel. See
Fig. 1 . Subtract first measurement from second measurement. On Dakota,
difference between both measurements should be 1.725-1.975" (43.82-50.
16 mm). On Durango, difference between both measurements should be 2.
78-3.02" (70.6-76.7 mm).
2) If necessary, adjust height differential to specification.
Adjust each front suspension arm by rotating torsion bar anchor
adjustment bolt clockwise to raise vehicle and counterclockwise to
lower vehicle. Always raise vehicle to correct height. If vehicle
height is greater than maximum specification, lower height to less
than specification, then back up to specification. After each
adjustment, jounce vehicle before measuring height to determine
effects of adjustment.

HOIST
CAUTION: On Ram Van/Wagon, ensure there is adequate drive shaft
clearance while raising vehicle. DO NOT raise vehicle by
hoisting or jacking against front lower control arms. If rear
axle, fuel tank, spare tire and liftgate will be removed for
service, place additional weight on rear end of vehicle. This
will prevent tipping as center of gravity changes.
Caravan, Ram Van/Wagon, Town & Country, & Voyager
To raise vehicle on single and twin post type hoists, ensure
hoist pads contact vehicle frame behind front control arm pivots and
inside rear wheels on rear axle housing. Always use hoist adapters.
See Fig. 2 or 5.
Dakota & Ram Pickup
Vehicle may be raised on single or twin post swiveling arm,
or ramp-type drive hoists. If using swiveling arm hoist, ensure
lifting arms, pads or ramps are positioned evenly on frame rails, and
adequate clearance is maintained for transfer case (4WD models) or
skid plate. All hoists must be equipped with adapters to properly
support vehicle. See Fig. 3.
WHEEL ALIGNMENT PROCEDURES
FRONT WHEEL CAMBER & CASTER ADJUSTMENT
CAUTION: DO NOT adjust caster by heating or bending suspension
components. If caster angle is incorrect, replace
component(s) causing incorrect angle.
Caravan, Town & Country, & Voyager
1) Caster is factory preset and cannot be adjusted. Camber is
factory preset, but can be adjusted with a camber service kit. Raise
and support vehicle. While holding lower strut attaching bolts
stationary, loosen attaching nuts. See Fig. 6. Remove upper attaching
nut and bolt. Install camber service kit attaching/adjusting bolt and
nut. While holding bolt stationary, lightly tighten nut. Repeat
procedure for lower attaching nut and bolt.
2) Lower vehicle until vehicle weight is supported by
suspension. Bounce vehicle several times and allow suspension to
settle. Rotate new cam bolt to move top of wheel in or out to
specified camber. See WHEEL ALIGNMENT SPECIFICATIONS table. Tighten
through-bolt nuts to specification. See TORQUE SPECIFICATIONS table.
