2. Visually inspect the exhaust pipes, muffler, and catalytic converter for any loose connections or damage.
3. Tighten any loose bolts or clamps on the exhaust system.
4. Replace any damaged components if necessary.

3. Check Engine and Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts.
2. Inspect for cracks or signs of wear.
3. If mounts are loose, tighten the bolts to the manufacturer’s specified torque (refer to service manual for specifications).
4. Replace any damaged mounts.

4. Inspect Heat Shield

Sub-steps:
1. Locate the heat shield around the exhaust system.
2. Check for any loose bolts or clips securing the heat shield.
3. Tighten or replace fasteners as necessary.

5. Examine Drive Belts

Sub-steps:
1. Check the drive belts for cracks, fraying, or excessive wear.
2. If any damage is found, remove the old belt and replace it with a new one, ensuring proper routing.
3. Adjust the tension as required.

6. Check Transmission Fluid
