Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working near electrical components.

2. Inspect Suspension Components

Tools Required: Jack, jack stands, socket set, torque wrench
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to gain access to the suspension components.
Inspect bushings, struts, and control arms for signs of wear or damage.
If bushings are cracked or deteriorated, they should be replaced.

3. Tighten or Replace Hardware

Inspect all bolts and nuts on the suspension assembly for tightness.
If any are found loose, tighten them to the manufacturer's specifications using a torque wrench.
Replace any missing or damaged hardware with OEM parts.

4. Lubricate Suspension Joints

Tools Required: Grease gun, appropriate lubricant
Apply grease to any grease fittings on the suspension joints and bushings to reduce friction and noise.
Wipe away excess grease to prevent dirt accumulation.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle back to the ground.
Reconnect the battery if it was disconnected.
Perform a test drive to verify the noise has been resolved.
