MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
1) a Pledge of Assurance to their Customers and 2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards
are continually re-published. In addition to these, standards for
Drive Train and Transmissions have recently been promulgated.
Participating shops utilize these Uniform Inspection & Communication
Standards as part of the inspection process and for communicating
their findings to their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers mediation and arbitration through MAP/BBB-CARE and other non-

profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method
has been incorporated which includes the "mystery shopping" of
outlets.
We welcome you to join us as we continue our outreach... with
your support, both the automotive repair industry and your customers
will reap the benefits. Please visit MAP at our Internet site www.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF SERVICE REQUIREMENTS & SUGGESTIONS
It is MAP policy that all exhaust, brake, steering,
suspension, wheel alignment, drive-line, engine performance and
maintenance, and heating, ventilation and air conditioning, and
electrical services be offered and performed under the standards and
procedures specified in these sections.
Before any service is performed on a vehicle, an inspection
of the appropriate system must be performed. The results of this
inspection must be explained to the customer and documented on an
inspection form. The condition of the vehicle and its components will
indicate what services/part replacements may be "Required" or
"Suggested". In addition, suggestions may be made to satisfy the
requests expressed by the customer.
When a component is suggested or required to be repaired or
replaced, the decision to repair or replace must be made in the
customer's best interest, and at his or her choice given the options
available.
This section lists the various parts and conditions that
indicate a required or suggested service or part replacement.
Although this list is extensive, it is not fully inclusive. In
addition to this list, a technician may make a suggestion. However,
any suggestions must be based on substantial and informed experience,
or the vehicle manufacturer's recommended service interval and must be
documented.
Some conditions indicate that service or part replacement is
required because the part in question is no longer providing the
function for which it is intended, does not meet a vehicle
manufacturer's design specification or is missing.
Example:
An exhaust pipe has corroded severely and has a hole in it
through which exhaust gases are leaking. Replacement of the
exhaust pipe in this case is required due to functional
failure.
Example:
A brake rotor has been worn to the point where it measures
less than the vehicle manufacturer's discard specifications.
Replacement of the rotor is required because it does not meet
design specifications.

if possible. If proper
adjustment cannot be obtained,
require repair or replacement
of worn component.

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.

1998-99 WHEEL ALIGNMENT
CHRY - Specifications & Procedures - Trucks & FWD Vans
Caravan, Dakota, Durango, Ram Pickup, Ram Van/Wagon,

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.
