• Excessive Bouncing: The car bounces excessively over rough surfaces.
• Tire Wear: Uneven tire wear patterns, indicating misalignment caused by sagging springs.

3. Tools and Materials Needed

Before starting the replacement process, gather the following tools and materials:

• Jack and Jack Stands: To elevate the vehicle safely.
