Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical issues during the repair.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to lift the vehicle and secure it on jack stands.
Remove Wheel:
- Remove the wheel where the noise is predominantly heard using a socket set.
Inspect Suspension Components:
- Check control arms, bushings, and sway bar links for wear.
- Use a pry bar to check for any play in the bushings.
Replace Worn Components:
- If any components are worn, remove them using the socket set.
- Install new parts ensuring they are torqued to manufacturer specifications (refer to the service manual for specific torque values).
- Common replacements may include control arms, bushings, or sway bar links.

3. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten all lug nuts.
Lower the vehicle off jack stands and torque the lug nuts to the specified values.

4. Test Drive

Conduct a test drive over bumps to check for any remaining noise.
