Maintenance & Troubleshooting
Signs of Wear & Troubleshooting
- The most common method of coil spring inspection is checking the vehicle ride height. This method will only catch the extreme cases of spring sag or leaning. In addition to checking ride height, look for these signs, which also indicate the coil springs require attention:
- Examine each coil spring for stress cracks, missing coils, or shiny spots between coils.
- Damaged bushings, bump stops, or MacPherson Struts.
- Front end of vehicle nose dives when braking or vehicle sway.
- Vehicles that commonly carry extra weight, resulting in unleveled condition most of the time.
Good Maintenance Practices
- Coil springs should be replaced in axle pairs to provide correct ride height and handling. Inspect the coil springs regularly for corrosion. Corrosion or rust causes the coil springs to weaken, leading to failure.
