Pre-Alignment Road Test With Customer

Perform a road test on the vehicle with the customer. The road test may help to identify many faulty parts such as:
- Control arm bushings
- Shock dampeners
- Power steering gear mounts
- Wheel bearings
- Tires
Obvious conditions must be brought to the customer's attention before beginning an alignment. A waddle feeling in the back of the vehicle often indicates the occurrence of a bent rim and/or a belt shift in 1 of the rear tires. Vibration in the steering wheel or in the floor pan is often the result of static imbalance or radial runout of the front tires.
