Hey guys, while I was driving today and about to get home, I heard this very strange rumbling sound coming from my engine. My car has 120k miles on it and is a 2009 auto g37x sedan. I did not want to drive any more so I only have a short video. The car does not make the sound when I rev the engine in park or netrual, only when I am rev the engine or drive while the transmission is in drive. Have no idea what it could be, just recently replaced my tensioner and ac compressor pullley and serptine belt so my belts and pulleys are fine. Ugh, thanks for the help gonna try to get the car to the dealer asap, just want to know if the car is safe to drive. Thanks.

Too much extraneous noise to isolate the rumble. Your video should be longer and begin while idling in park.
