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.

(1) - Require replacement of units where dents restrict shock
or strut piston rod movement. If dents don't restrict
movement, no service is suggested or required. Especially
critical on mono-tube shocks.
( 2) - This condition can lead to damage of the piston rod,
which, in turn, causes premature piston rod seal wear.
( 3) - Only required if replacing cartridge.
( 4) - CAUTION: If the strut cartridge has been replaced previously,
the oil on the strut housing may be filler oil. The
technician must identify the source of the oil.
( 5) - If noise is isolated to shock or strut, suggest
replacement.
( 6) - Although shocks or struts may have contributed to tire
cupping, an inspection is needed of the entire suspension
system. If the shock or strut is found to be contributing
to the tire cupping, require replacement.

SPRINGS - COIL, LEAF AND TORSION BAR
When springs are replaced, it is suggested, but not required,
that both springs on an axle be replaced to maintain equal height from
side to side and to provide a balanced ride and proper handling.
When variable rate springs are installed in place of
conventional coil springs, they must be installed in axle sets to
ensure proper handling, uniform ride, and proper chassis height.
Erroneous height measurements may result from: improper tire
inflation, non-standard tire or wheel size, and heavy load in vehicle
or trunk.

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.
