All of a sudden, I started hearing a jackhammering noise underneath the car as I was decelerating/coasting. It is more pronounced going downhill... I don't really hear it while
driving... Engine sounds smooth , its more of a drivetrain noise and it seems to be toward the front of the car.. it's louder based on speed...
Yikes! I'd take a look at the u-joints on all driveshafts.

Do you have an AWD model?
