Component Tests
Ball Joint Inspection
1. Raise and support the vehicle. Refer to Section 100 - 02 .
2. Prior to performing any inspection of the ball joints, inspect the wheel bearings.
3. Position a safety stand beneath the front suspension lower arm (3079) to be tested.
4. While an assistant pulls and pushes the bottom of the tire, observe the relative movement between the lower spindle arm and the front suspension lower arm ball joint. Any movement at
or exceeding the specification indicates a worn or damaged lower ball joint. Install a new front
suspension lower arm. Refer to Section 204 - 01 . z

Front
1. Start the engine and center the steering wheel.
2. Turn the engine off, and hold the steering wheel in the straight forward position by attaching a rigid link from the steering wheel to the seat.
3. Check the toe settings. Follow the manufacturer's instructions.
4. Remove the clamps.
5. Loosen the nuts. zClean and lubricate the nut(s) and front wheel spindle tie- rod threads.
6. NOTE: Do not allow the steering gear bellows to twist when the front wheel spindle tie- rod
(3280) is rotated.
Rotate the front wheel spindle tie- rods.

REMOVAL AND INSTALLATION
Wheel Knuckle —
Cobra
Removal CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number must be installed if installation becomes necessary. If substitution is
necessary, the part must be of the same finish and property class. Torque values must be used
as specified during reassembly to make sure of correct retention of these parts.
1. Mark the rear shock absorber (18125) relative to the protective sleeve with the vehicle in a static, level ground position (curb height).
2. Raise the vehicle on a hoist. For additional information, refer to Section 100 - 02 .
3. Remove the wheel and tire assembly. For additional information, refer to Section 204 - 04 .
4. Remove and discard the rear hub retainer (4B477).

DESCRIPTION AND OPERATION
Wheels And Tires
WARNING: Do not mix different types of tires, such as radial, bias, or bias- belted, on the
same vehicle except in emergencies. Vehicle handling can be seriously affected and can result
in loss of control.
Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including
full- rated load capacity when inflated to recommended inflation pressures.
Tire and Wheel Runout
Excessive radial and lateral runout of a wheel and tire assembly can cause roughness, vibration,
wheel tramp, tire wear, and steering wheel tremor.
Before checking runout, and to avoid false readings caused by temporary flat spots in the tires, check
runout only after the vehicle has been driven far enough to warm the tires. For additional information,
refer to Section 100 - 04 .

z have elongated wheel hub bolt holes.
z have excessive lateral or radial runout.
Wheel and tire assemblies are attached by six wheel nuts.
It is mandatory to use only the tire sizes recommended on the tire chart attached to the vehicle. Larger
or smaller tires can damage the vehicle, affect durability, and require changing the speedometer
calibration. Make sure wheel size and offsets match those recommended for the tire in use. 1. Inspect for signs of uneven wear that may indicate a need for balancing, rotation, front suspension alignment, damaged tie- rod, or steering components.
2. Check tires for: zcuts.
z stone bruises.
z abrasions
z blisters.
z embedded objects.
3. Tread wear indicators are molded into the bottom of the tread grooves. Install a new tire when the indicator bands become visible.
