Issue:
In the event of customer complaints of a vibration through the steering wheel and/or the seat, a procedure can be followed in order to rectify the concern.
Action:
If a customer complaint is received and the wheels and tires are suspected, the following workshop procedure must be followed to assist in the
rectification of the concern.
WORKSHOP PROCEDURE
1.
Prior to any rectification work, the vehicle must be inspected for any damage to the wheels and tires.
2.
Check the tire pressures and visually inspect the suspension components for tightness.
3.
Drive the vehicle for a distance of 24-32 Km (15-20 miles, approximately) at a speed of 80 Km/h (50 mph) to warm the tires and eliminate the
possibility of incorrect diagnosis due to flat spotting of the tires.
Note:
This procedure needs to be carried out prior to any analysis work being undertaken. Driving the vehicle as recommended will work out any
temporary flat spotting that may have occurred in the tires, especially if the vehicle has been parked for an extended period of time.
4.
Once the tires are heated, the WDS Vehicle Vibration Analyzer (VVA) procedure must be carried out to determine the possible source of
vibration.
