my Toyota Corolla E210 (2019-2024) makes a loud noise when I accelerate, what's wrong?

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is on a level surface and securely supported with jack stands if raised.
• Disconnect the battery to ensure safety while working on electrical systems.

2. Inspect and Repair Exhaust System

• Sub-steps:
  1. Remove any heat shields or covers obstructing access to the exhaust system.
  2. Examine all exhaust pipes, muffler, and catalytic converter for cracks or holes.
  3. If damage is found, cut out the damaged section using a reciprocating saw.
  4. Install a new exhaust section using exhaust clamps or weld if necessary.
  5. Reattach heat shields and covers.

3. Check and Replace Engine Mounts (if necessary)

• Sub-steps:
  1. Remove the bolts securing the engine mount to the engine block using a socket wrench.
  2. Support the engine with a jack or engine support bar.
  3. Remove the old engine mount and install the new one, ensuring proper alignment.
  4. Torque the bolts to the manufacturer’s specifications (typically around 40-50 ft-lbs).
  5. Lower the engine and recheck all connections.

4. Reassemble and Reconnect Battery

• Reinstall any components removed during inspection and repair.
• Reconnect the battery and ensure all connections are tight.
