Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear (depending on the noise location) of the vehicle.
Secure with jack stands to ensure safety.

3. Inspect and Replace Components

A. Control Arms and Bushings

Remove the wheel to access the control arms.
Use a socket set to unbolt and remove the control arm.
Inspect bushings for wear; replace if cracked or soft.
Reinstall the new control arm and torque bolts to manufacturer specifications (usually between 30-50 Nm).

B. Struts and Shocks

Remove the strut assembly by unbolting it from the knuckle and the top mount.
Inspect for leaks; replace if damaged.
Install the new strut, ensuring proper alignment and torque the top mount bolts to manufacturer specifications.

C. Sway Bar Links

Locate the sway bar links and use a wrench to remove them.
Check for breaks or excessive play; replace if necessary.
Reinstall new sway bar links and torque to specification.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Tighten lug nuts to the specified torque (usually around 90-100 Nm).
