Disconnect the battery to ensure safety while inspecting electrical components.

2. Inspect and Secure Components

Tools Required: Socket set, torque wrench
Inspect the undercarriage and engine mounts for any signs of damage or looseness.
- Tighten any loose bolts to the manufacturer-specified torque settings.
Examine the exhaust system for any loose brackets or damaged sections.
- Re-secure or replace damaged components as necessary.

3. Check the Suspension System

Tools Required: Jack and jack stands, torque wrench
Lift the vehicle using a jack and secure it with jack stands.
