5. Maintenance

Once installed, these bushings are designed for long-term performance with minimal maintenance.

If you experience any of the following symptoms after installation or during the lifespan of the bushings, it may indicate an issue with the suspension system, potentially including the bushings:

• Noisy Suspension: Clunking, squeaking, or rattling sounds, especially over bumps.
• Sloppy Handling: Loose steering, excessive play, or difficulty maintaining a straight line.
• Uneven Tire Wear: Abnormal wear patterns on tires, which can indicate alignment issues.
• Difficulty with Alignment: Inability to achieve or maintain proper wheel alignment.

If any of these symptoms occur, it is crucial to have your vehicle inspected by a professional technician immediately to diagnose the root cause and perform necessary repairs.
