Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather all necessary tools and parts for the repair.

2. Inspect and Replace Suspension Components

Raise the Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel:
- Use a socket set to remove the wheel on the side where the noise is occurring.
Inspect Struts/Shocks:
- Check for leaks or physical damage. If damaged, replace with OEM or quality aftermarket struts/shocks.
Replace Bushings:
- Remove old bushings using a bushing removal tool if necessary. Install new bushings following manufacturer specifications.
Reassemble:
- Reattach the wheel and lower the vehicle back to the ground.

3. Inspect and Replace Drivetrain Components

Check CV Joints:
- Inspect the CV boots for tears and the joints for play. Replace the CV axle if damaged.
Inspect Differential:
- Check for abnormal noise when rotating the wheels by hand. If noise persists, consider replacing differential fluid and checking for internal damage.
