Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, suspension tester, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Components

Control Arms and Bushings:
- Remove the bolts securing the control arms to the chassis.
- Inspect bushings for cracks or excessive wear; replace if necessary.
- Torque the new control arm bolts to manufacturer specifications (typically around 70-80 Nm).
Struts:
- Remove the strut assembly by unbolting from the top mount and lower control arm.
- Inspect for leakage and damage. Replace if worn.
- Reinstall the new strut and torque to specifications (typically around 100-120 Nm).
Sway Bar Links and Bushings:
- Remove the sway bar link bolts and inspect for play or wear.
- Replace if necessary; torque to specifications (typically around 50-60 Nm).

4. Reassemble and Lower the Vehicle

Reattach any components that were removed during inspection and replacement.
Double-check all bolts are torqued to specifications.
Lower the vehicle back to the ground and remove jack stands.

5. Final Checks

Reconnect the battery.
Start the vehicle and perform a test drive to ensure noises are eliminated.
