Solution

1. Preparation

Gather tools: socket set, torque wrench, jack and jack stands, rubber mallet, pry bar.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Tighten Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Use a socket set to check and tighten all visible bolts on the struts, control arms, and sway bar links.
If any bolts are found to be damaged, replace them with OEM fasteners.

3. Replace Worn Shock Absorbers or Struts

Remove the wheel corresponding to the noisy side.
Use a socket set to remove the bolts securing the shock absorber or strut to the vehicle.
Disconnect any electrical connectors if applicable (e.g., for active suspension systems).
Replace with new shock absorbers or struts, following manufacturer specifications for torque values.
Reinstall the wheel and lower the vehicle.

4. Additional Component Inspection

Use a pry bar to check for play in control arms and bushings; replace any that are worn or damaged.
Inspect the sway bar bushings and links; replace if cracked or excessively worn.
Reassemble any components that were removed for access, ensuring they are secured properly.
