When driving there is a loud noise coming from front end and not sure why. Also alot of things with my front end is messed up it seems. The noise is one of the worst and also getting louder as time passes.
There was a noise coming from the engine side of the vehicle, but it was a separate noise from that of the engine. It was like a rattling/loud sound. Every time I would turn to the right and also reverse, the sound was louder. I took it to the Nissan technician and they found the motor mount was broken. After replacing the motor mount the vehicle sound just like new (just how is was supposed to sound).
