Why is the 2.4 Motor so loud in the Chevy Equinox ? New transmission (unrelated) ,new tires, no wheel bearing issues. There are so many stories that have the same issues.Is it a lack of sound deadening in the body ? The same story can be read over and over ,you get a rumble at around 40MPH and it continues to 70 mph. I have put it in neutral and it doesn't change at all while coasting at 60 mph.
