Disconnect the negative terminal of the battery to avoid any electrical issues.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers:
- Remove the wheel on the affected side using a socket set.
- Check the shock absorber for any signs of leakage or wear.
- If damaged, replace with OEM or high-quality aftermarket shocks.
Replace Bushings:
- Use a bushing removal tool to extract worn bushings.
- Apply silicone grease to the new bushings before installation.
- Install the new bushings following the manufacturer's torque specifications.
Tighten Fasteners:
- Check and tighten all suspension-related bolts to the specified torque value using a torque wrench.
- Ensure all fasteners are secure and in good condition.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Perform a test drive over bumps to confirm the squeaking sound has been resolved.
