- Use a socket set to remove the screws/bolts securing the wheel well covers.
- Carefully detach the covers to access the suspension and drivetrain.
Check Drive Unit:
- Inspect the drive unit visually for any signs of physical damage or loose connections.
- Tighten any loose bolts to the manufacturer's torque specifications (consult service manual for exact torque values).
Inspect Suspension Components:
- Examine the suspension for wear or damage, including control arms and bushings.
- Replace any worn components as necessary.
