- The problem
- In certain high salt areas, the idler arm is exposed to road salt which causes the dust seal to deteriorate resulting in idler arm pin corrosion. This causes the pin to freeze and break. Consequence of defect: a broken idler arm pin could result in loss of steering control and may cause an accident.
- The fix
- Replace pin with one of improved corrosion resistant quality.
