Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if electrical components are involved.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Strut and Shock Absorbers:
- Remove the wheel to access the suspension.
- Unbolt the strut from the top mount and lower control arm.
- Replace the strut or shock absorber with a new one.
- Torque the bolts to the manufacturer's specifications (typically around 50-70 Nm for strut mounts).
Bushings:
- Remove any necessary components to access the bushings.
- Use a bushing removal tool or a press to remove the old bushings.
- Install new bushings, ensuring they are properly seated.
Strut Mounts:
- Inspect and replace the strut mounts if visible wear is present.
- Ensure they are torqued to specifications (around 20-30 Nm).

4. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle.
Reconnect the battery if it was disconnected earlier.

5. Test Drive

Carefully test drive the vehicle to ensure the noise is resolved and check for proper handling.
