Signs of Wear & Troubleshooting

• Vehicle wandering: unstable steering or vehicle drifting may indicate worn suspension components.
• Unexpected vibration: sudden vibration while driving at speed may be a sign of problems in your suspension system.
• Unexpected noises: banging or clunking sounds while driving may indicate problems in your suspension system requiring urgent repair, while screeching sounds while driving may indicate an overall weakening of your suspension system.

Good Maintenance Practices

• Inspect or have your trailing arm inspected. Your vehicle's suspension and steering systems are critical for safe and stable vehicle function. Proper maintenance and regular inspection is therefore vital to the health of your vehicle. Inspect your steering and suspension system components regularly, following exposure to events that may harm the components, or when you experience signs of wear.
