DETAILED TEST C : WHEEL AND TIRE

CONDITIONS

DETAILS/RESULTS/ACTIONS

ROAD TEST THE VEHICLE

Wheel or tire vibrations felt in the steering wheel are most likely related
to the front wheel or tire. Vibration felt through the seat are most likely
related to the rear wheel or tire. This may not always be true, but it can
help to isolate the problem to the front or rear of the vehicle.
Test drive the vehicle at different speed ranges.

During the road test, if the vibration can be eliminated by placing the
vehicle in neutral or is affected by the speed of the engine, the cause is not
the wheels or tires.

! Is there a vibration and noise ?

! YES
Go toC2.

! NO
The wheel and tires are OK. Conduct a diagnosis on other suspect
systems.

CHECK THE FRONT WHEEL BEARINGS

Check the front wheel bearings.
Refer to Wheel Bearing Check (See DS group - front axle).

! Are the wheel bearings OK ?

! YES
Go toC3.

! NO
Inspect the wheel bearings. Adjust or Repair as necessary. Test the system
for normal operation.

INSPECT THE TIRES

1. Check the tires for missing weights.
2. Check the wheels for damage.
