Signs of alignment problems include a crooked steering wheel when driving straight. Uneven tire wear is another sign. An alignment check should be part of regular maintenance. Mechanics use specialized machines to measure and adjust your Avalon’s alignment. This ensures all wheels are parallel. It also ensures they have the right angle to the road.
Replacing Suspension Components
The suspension system absorbs shocks from the road. It allows the Avalon to move smoothly. Over time, suspension parts like struts and shocks can wear out. This can lead to a bumpy ride. It also affects handling and braking. Regular inspection helps catch issues early. A mechanic can replace worn components. This restores comfort and safety. New struts and shocks improve ride quality. They also maintain tire contact with the road. Replacing these parts can revive your Avalon’s performance.
| Component | Signs of Wear | Benefits of Replacement |
|---|---|---|
| Struts and Shocks | Uneven tire wear, bouncy ride | Better handling, smoother ride |
| Wheel Alignment | Crooked steering wheel, car pulling | Even tire wear, improved safety |
- Check alignment regularly.
- Inspect suspension parts for wear.
- Replace worn struts and shocks.
Remember: Well-maintained suspension and steering extend your car’s life. They also ensure a safe, comfortable drive.
