DETAILED TEST C: WHEEL AND TIRE

CONDITIONS DETAILS/RESULTS/ACTIONS

C1 ROAD TEST THE VEHICLE

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 to C2 .

NO

The wheel and tires are OK. Conduct a diagnosis on other suspect systems.

C2 CHECK THE FRONT WHEEL BEARINGS

NOTE:

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.
