Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any accidental electrical issues while working on the vehicle.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands to ensure safety during the repair process.

3. Remove the Affected Components

For Strut Replacement:
1. Remove the wheel to access the strut assembly.
2. Disconnect the brake line bracket from the strut.
3. Remove the top strut mount bolts from the engine bay.
4. Unbolt the strut from the lower control arm and gently remove the strut assembly.
For Sway Bar Link Replacement:
1. Locate the sway bar links connected to the control arms.
2. Use a wrench to remove the nuts securing the sway bar links.
3. Remove the sway bar link from the vehicle.

4. Inspect and Replace Components

Inspect the struts and sway bar links for wear and replace if necessary.
Replace worn bushings in control arms or sway bar links by pressing out the old bushings and pressing in new ones.

5. Reassemble Suspension Components

Reinstall the strut assembly by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.
Reattach the sway bar links and ensure they are securely fastened.

6. Lower the Vehicle and Test

Carefully lower the vehicle back to the ground using the jack.
Reconnect the battery and perform a test drive to ensure the clunking noise has been resolved.
