Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar, stethoscope.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery for safety.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle on jack stands to ensure stability during the repair process.

3. Inspect and Replace Worn Components

Shocks and Struts:
- Remove the bolts securing the shock or strut to the vehicle using a socket set.
- Inspect for leaks or physical damage.
- If damaged, replace with OEM or quality aftermarket parts, ensuring they meet specifications.
Bushings:
- Use a pry bar to check for excessive play in bushings.
- If worn, remove old bushings and replace with new ones, applying lubricant if necessary.

4. Tighten Loose Components

Inspect all bolts and fasteners associated with the suspension system.
Tighten any loose bolts to the manufacturer’s specified torque setting using a torque wrench.

5. Reassemble and Lower Vehicle

Reinstall any components removed for inspection or replacement.
Ensure all bolts are secure.
Lower the vehicle from the jack stands and remove the jack.

6. Final Checks

Reconnect the battery.
Test drive the vehicle to confirm that the noise has been resolved.
