DETAILED TEST C : WHEEL AND TIRE
CONDITIONS
DETAILS/RESULTS/ACTIONS
C1 ROAD TEST THE VEHICLE
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.
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
Check the front wheel bearings.
Refer to Wheel Bearing Check (See DS group - front axle).
●
Are the wheel bearings OK ?
⇒
YES

●
Do the tires have an abnormal wear pattern ?
⇒
YES
Correct the condition that caused the abnormal wear. Install new tire(s).
Test the system for normal operation.
⇒
NO
Go to C4.
C4 TIRE ROTATION DIAGNOSIS
1.
Spin the tires slowly and watch for signs of lateral runout.
