5. Maintenance

Ball joints are designed to be largely maintenance-free due to their sealed construction. However, regular inspection is crucial for ensuring their longevity and your vehicle's safety.

5.1. Inspection Schedule

• Inspect ball joints during routine vehicle maintenance, such as tire rotations or oil changes.
• Look for signs of wear, such as torn or cracked rubber boots, excessive play in the joint, or unusual noises (e.g., clunking, popping) when driving over bumps or turning.

5.2. Cleaning

Keep the area around the ball joint clean to prevent accumulation of dirt and debris that could compromise the boot's integrity.

6. Troubleshooting

If you suspect an issue with your suspension ball joint, consider the following common symptoms and potential causes. Always consult a qualified mechanic for diagnosis and repair.
