Solution

1. Preparation

Gather necessary tools and parts.
Lift the vehicle using a jack and secure it on jack stands.
Ensure the vehicle is on a flat surface and securely supported before beginning work.

2. Inspect and Replace Worn Components

A. Shock Absorbers

Sub-steps:
- Remove the wheel to access the shock absorber.
- Unbolt the top mounting nut and the bottom bolts using a socket set.
- Remove the old shock absorber and replace with a new one, ensuring correct orientation.
- Torque bolts to manufacturer specifications (typically around 30 Nm for upper mount and 90 Nm for lower bolts).

B. Sway Bar Links

Sub-steps:
- Locate the sway bar links attached to the sway bar and control arm.
- Remove the nuts securing the sway bar links using a wrench.
- Replace with new sway bar links, ensuring they are tightened to specification (generally around 50 Nm).
- Reattach the sway bar links, checking for any binding or movement.

C. Control Arm Bushings

Sub-steps:
- Remove the control arms by unbolting them from the chassis and the steering knuckle.
- Cut or press out the old bushings using a bushing removal tool.
- Install new bushings and reassemble the control arms, torquing to specification (usually around 70 Nm).

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Perform a test drive to confirm the clunking noise has been resolved.
