Torque the tensioner back to specification.

4. Brake System Inspection

Tools Required: Jack and jack stands, lug wrench
Lift the vehicle and remove the wheels to access the brake components.
Inspect brake pads for excessive wear and replace if necessary.
Check the brake calipers for proper operation and ensure they are not stuck.

5. Exhaust System Check
