Inspect Shock Absorbers:
- Remove the lower mounting bolts using a socket set.
- Pull the shock absorber out of its mounting position.
- Check for leaks or damaged seals. If damaged, replace with new shock absorbers.
Replace Worn Bushings:
- Identify the bushings on control arms and sway bar links.
- Use a bushing removal tool or a press to remove old bushings.
- Install new bushings, ensuring they are properly seated.

3. Tighten or Replace Hardware

Inspect and Tighten Bolts:
- Check all suspension bolts for torque specifications (refer to the vehicle’s service manual).
- Tighten any loose bolts to the manufacturer’s specified torque values.
Replace any damaged hardware:
- If bolts or nuts are stripped or damaged, replace them with OEM parts.

4. Reassemble and Test

Reinstall any components that were removed for inspection.
Reconnect the battery and lower the vehicle.
Perform a test drive to ensure noise is resolved.
