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.

same vehicle, the radials must be on the rear axle,

except for high-pressure temporary spares.

(3) - Excessive is defined as enough to contribute to

performance problems. Match mounting may correct

run-out. If not, require replacement of appropriate

part. Refer to manufacturer’s specifications.

(4) - Most manufacturers do not recommend tubes in tubeless

tires. Inspect tire and wheel assembly to determine

the reason for a tube in tubeless tire. Recommendation

for repair or replacement should be based upon condition

of tires and/or wheel listed in these guidelines.
