Wheel Alignment
PRE-ALIGNMENT INSPECTION PROCEDURES
PRE-ALIGNMENT CHECKS
Before making wheel alignment adjustment, perform the
following checks:
1) Tires should be equal in size and runout must not be
excessive. Tires and wheels should be in balance, and inflated to
manufacturer's specifications.
2) Wheel bearings must be properly adjusted. Steering linkage
and suspension must not have excessive looseness. Check for wear in
tie rod ends and ball joints.
3) Steering gear box must not have excessive play. Check and
adjust to manufacturer's specifications.
4) Vehicle must be at curb height with full fuel load and
spare tire in vehicle. No extra load should be on vehicle.
5) Vehicle must be level with floor and with suspension
settled. Jounce front and rear of vehicle several times and allow it
to settle to normal curb height.
6) If steering wheel is not centered with front wheels in
straight-ahead position, correct by shortening one tie rod adjusting
sleeve and lengthening opposite sleeve equal amounts.
7) Ensure wheel lug nuts are tightened to torque
specifications.

RIDING HEIGHT ADJUSTMENT
Before adjusting alignment, check riding height. Ensure
vehicle is on level floor and tires are properly inflated. Bounce
vehicle several times and allow suspension to settle.
Visually inspect vehicle, from front to rear or side to
side, for signs of abnormal height. Remove extra heavy items from
passenger and luggage compartments. If riding height is not within
specification, check and repair suspension before adjusting alignment.

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-
Page 779 of 1333
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.
Page 781 of 1333
the facts, allowing the customer to draw their own
conclusions and make an informed decision about how to
proceed.
STEERING AND SUSPENSION
SERVICE PROCEDURES REQUIRED AND SUGGESTED FOR PROPER VEHICLE
OPERATION
Steering and suspension are complex systems made up of a
variety of interdependent components. For proper vehicle handling,
ride, and tire wear, a thorough inspection is required whenever
suspension work is being performed.
Conditions listed assume that the problem has been isolated
to the specific component by proper testing procedures.
NOTE: When replacing steering and/or suspension components which
may affect an alignment angle, you are required to check
and adjust alignment as needed. Refer to the OEM
specifications.
CAUTION: DO NOT use ride height altering or load compensating
components, such as variable rate springs and coil over
shocks, on vehicles with height or load sensing
proportioning valve-equipped braking systems, unless
these components are original equipment.
AIR RIDE SUSPENSION
NOTE: Depending on the air suspension design, there are some
aftermarket products available to eliminate the air ride
suspension on certain vehicles. If the system has been
eliminated with one of these products, then no service is
suggested or required.
AIR RIDE SUSPENSION - AIR SHOCKS AND AIR STRUTS
NOTE: This section covers the air spring portion of the
air shock or strut. For damping portion of shock
or strut conditions and procedures, refer to the
SHOCK ABSORBERS, STRUT CARTRIDGES AND STRUT ASSEMBLIES
section.
