2. Inspect Exhaust System

Tools Required: Jack and jack stands, socket set, exhaust leak detector (or soapy water).
Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the exhaust system for any visible damage, rust, or holes.
Use an exhaust leak detector or spray soapy water on joints; bubbles indicate leaks.
If leaks are found, proceed to replace the affected components.

3. Check Drivetrain Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect the driveshaft and differential for any signs of wear or damage.
Check the U-joints for play; replace if worn.
Ensure all bolts are tightened to manufacturer specifications.
If the driveshaft is damaged, remove it and replace it with a new one.

4. Address Engine Components

Tools Required: OBD-II scanner, multimeter, basic hand tools.
Scan the vehicle for trouble codes and address any issues indicated.
Inspect belts for wear or damage and replace if necessary.
Tighten any loose components in the engine compartment that may be causing noise.
