Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Worn Components

Inspect Struts/Shocks:
- Remove the wheel using a socket set.
- Check for oil leakage on the struts/shocks, indicating failure.
- Replace with OEM or quality aftermarket parts if necessary.
Check Sway Bar Links:
- Examine sway bar links for play or damage.
- If worn, remove the nuts using the appropriate socket, then install new sway bar links.
- Torque the nuts to manufacturer specifications (typically around 40-50 ft-lbs).
Inspect Bushings:
- Check control arm bushings for cracks or deterioration.
- If damaged, remove the control arm and press out the old bushings.
- Install new bushings and reassemble the control arm.

3. Reassemble and Test

Replace the wheel and torque the lug nuts to the specified value (typically around 80-100 ft-lbs).
Lower the vehicle and remove any safety equipment.
Test drive the vehicle to confirm the clunking noise is resolved.
