Perform a number of checks before attempting a vehicle alignment. Loose or worn suspension parts prevent an accurate setting of alignment angles. Checks should include:
- The tires should be checked for proper inflation pressures.
- Check the tires for normal tread wear.
- Check the front hub and bearing assembly for excessive wear.
- Check the ball joints and tie rods for looseness.
- Inspect the wheels and tires for runout, resulting from bent wheels or faulty tires.
- The vehicle trim height should be checked. If the trim heights are not within specification, it will be necessary to make corrections before adjusting the alignment.
- The steering gear should be checked for looseness.
- The struts should be inspected for wear or damage.
- The control arms should be checked for loose or worn bushings.
- The stabilizer shaft (sway bar) attachments should be checked for loose or missing components.
- The frame fasteners should be checked for proper torque.
- The frame insulators should be checked for wear or damage.
