Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Safety gear: gloves and safety glasses.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear end of the vehicle, depending on where the noise is coming from.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Damaged Components

Inspect Struts and Shocks:
- Remove the wheel to gain access to the suspension components.
- Check for leaks or physical damage on the struts/shocks.
- If any are damaged, proceed to remove and replace them.
Replace Struts/Shocks:
- Remove the bolts securing the strut/shock to the lower control arm and top mount.
- Install the new strut/shock in reverse order.
- Torque specifications: Refer to the service manual for specific torque values.
Inspect Sway Bar Links:
- Check the sway bar links for any damage or looseness.
- If worn, remove the bolts securing the sway bar link and replace with a new part.
- Torque specifications: Refer to the service manual.

4. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts to the manufacturer’s specifications.
Lower the vehicle from the jack stands and remove the jack.
