my Toyota Corolla E210 (2019-2024) has a loud noise when I accelerate, what’s the issue?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect Exhaust System

• Tools Required: Socket set, flashlight
• Inspect the entire exhaust system from the manifold to the tailpipe.
• Look for any cracks, holes, or rusted areas.
• Tighten any loose bolts or clamps.
• Replace any damaged sections with new exhaust components if necessary.

3. Check Engine and Transmission Mounts

• Tools Required: Wrench set, pry bar
• Inspect all engine and transmission mounts for signs of wear or damage.
• Use a pry bar to check for excessive play in the mounts.
• Replace any damaged mounts with OEM parts, ensuring proper torque specifications (typically around 30-50 ft-lbs for most mounts, but refer to service manual for exact values).

4. Reconnect Battery

• Reconnect the battery terminals, ensuring they are tight and free of corrosion.

5. Test Drive

• Start the vehicle and take it for a test drive to see if the noise persists.
• Pay attention to the noise level during acceleration and monitor for any abnormal vibrations.
