Specifications & Procedures: Adjustments: Notes

Before making any adjustments, the following checks and inspections should be made to ensure correctness of alignment readings and alignment adjustments:

• Check all tires for proper inflation pressures and approximately the same tread wear.
• Check for loose ball joints. Check tie-rod ends. If excessive looseness is noted, it must be corrected before adjusting.
• Check for run-out of wheels and tires.
• Check vehicle trim heights. If out of limits and a correction is to be made, it must be made before adjusting toe-in.
• Check for loose control arms.
• Check for loose or missing stabilizer bar attachments.
• Consideration must be given to excess loads, such as tool boxes. If this excess load is normally carried in vehicle, it should remain in vehicle during alignment checks.
• Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
• Regardless of equipment used to check alignment, vehicle must be on a level surface.
