What is causing my Vauxhall Vivaro to make a loud knocking noise?

I have noticed that my Vauxhall Vivaro is making a loud knocking noise every time I accelerate. I've checked the engine and everything seems to be in good condition. What could be causing this and what steps should I take to fix it?

The most common cause of a loud knocking noise in a Vauxhall Vivaro is a worn out engine bearing. This can happen over time due to regular wear and tear. It is important to get this fixed as soon as possible to avoid further damage to the engine.

Another possible cause of the knocking noise could be a loose or damaged suspension component. This can happen if you frequently drive on bumpy roads or if you hit a pothole. Make sure to have your suspension checked by a mechanic.

It is also possible that the knocking noise is coming from a faulty exhaust system. If you notice any changes in your exhaust sound or if you see any visible damage, it's important to have it inspected and repaired.

I would recommend taking your Vauxhall Vivaro to a trusted mechanic for a thorough inspection. They will be able to diagnose the problem and provide you with the best solution to fix the knocking noise.
