Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle using jack stands for safety.

3. Inspect and Replace Damaged Components

Inspect Struts/Shocks:
- Check for oil leakage or damage to the struts/shocks.
- If damaged, remove the strut assembly by unbolting the top mount and lower bolt. Use a strut spring compressor if necessary.
- Replace with new struts/shocks, ensuring proper torque specifications (typically around 30-40 Nm for top mounts and 80-100 Nm for lower bolts).
Inspect Control Arms:
- Look for cracks or wear on the control arms and bushings.
- If replacement is required, remove the bolts securing the control arm to the chassis and the steering knuckle.
- Install the new control arm, torque bolts to manufacturer specifications (usually around 100 Nm).
Check Sway Bar and Bushings:
- Inspect the sway bar links and bushings for wear.
- Replace any damaged sway bar links by removing the bolts using a socket set, and install new ones, tightening to manufacturer torque specifications.

4. Reassemble and Lower the Vehicle

Ensure all components are secure and properly torqued.
Remove jack stands and lower the vehicle back to the ground.
Recheck all fasteners after the weight of the vehicle is applied.
