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.
