Preliminary Inspection

Steering and vibration problems are not always the result of improper alignment. They may also be caused by wheel and tire imbalance, or other factors. To ensure correct alignment readings, the following inspections should be done and corrections made before checking caster, camber or toe:
1. Inspect all tires for proper inflation pressures and even tread wear.
2. Inspect wheel bearings for looseness.
3. Inspect ball joints and tie rod ends for excessive looseness.
4. Inspect steering gear operation and mountings.
5. Inspect operation of struts.
6. Inspect control arms.
7. Inspect hub and bearing assemblies for excessive wear.
