Control Arms and Bushings:
- Visually inspect control arms for cracks or bends.
- Check bushings for deterioration. Replace if worn.
Struts and Shocks:
- Remove the strut assembly.
- Inspect for leaks or damage. Replace if necessary.

4. Examine Drivetrain Components

CV Joints and Axles:
- Inspect CV boots for ruptures. Replace if torn.
- Check for play in the joints. Replace axle shafts if necessary.
Engine and Transmission Mounts:
- Inspect mounts for cracks or separation.
- Replace any faulty mounts to eliminate noise.

5. Reassembly

Reinstall all components in the reverse order of removal.
Ensure all bolts are torqued to the manufacturer’s specifications (refer to the vehicle repair manual).
Reinstall the wheels and lower the vehicle.
