Alignment: Tools and Equipment






Equipment used for front-wheel alignment inspection must be accurate. All wheel alignment readings must be performed on an alignment rack level to within 1.5 mm (1/16 inch) side-to-side and front-to-rear. The instrumentation used must have a means of compensating for wheel runout.

The alignment rack must be level and the front tires positioned on swivel plates. If using magnetic-type hub gauges, the lug bolt must be removed and replaced with hub gauge adapters. Clip-on type gauges may be seated directly on the face of the wheel bearing bore once the hub grease cap is removed.

Install the wheel alignment equipment on the vehicle and follow the installation and inspection instructions provided by the manufacturer.
