Lead/Pull Description

Lead is the deviation of the vehicle from a straight path on a revel road, without hand pressure on the steering wheel. Lead is usually the result of one of the following conditions:
1. Tire construction. Refer to VIBRATION DIAGNOSIS AND CORRECTION in SUSPENSION GENERAL DIAGNOSIS.
2. Uneven parking brake adjustment. Refer to PARK BRAKE CABLE SERVICE/ADJUSTMENT in BRAKES.
3. Wheel Alignment

The way in which a tire is built may produce lead. Rear tires do not cause lead.
