Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle and support it with jack stands.
Ensure that the vehicle is securely elevated before proceeding.

3. Inspect Suspension Components

Strut Inspection: Check for leaking fluid around the struts. If leaking, replace struts.
Bushing Inspection: Inspect control arm and sway bar bushings for cracks or excessive wear. Replace any damaged bushings.
Ball Joint Inspection: Check the ball joints for play. If they are loose, replace the ball joints.

4. Verify Wheel Assembly

Loose Wheel Nut Check: Use a torque wrench to ensure that all wheel nuts are tightened to the manufacturer's specifications.
Wheel Bearing Inspection: Spin the wheel and listen for any grinding noises. If grinding is present, replace the wheel bearings.

5. Address Exhaust Issues (if applicable)

Inspect the exhaust hangers and mounts for damage or detachment. Replace any broken mounts or hangers to eliminate noise.
