There is a loud noise/clunk/thump/click/bump sound that occurs when I enter a driveway that is steep. I enter it slowly at an angle, 45 degrees, almost feels like I end up on 2 wheels, almost as though the car tilts and sometimes I hear one of the rear tires lose traction. I always enter the driveways very slow and at an angle to prevent the front from getting scratched. Does anyone hear that? I think the sound is coming from near the rear tire. Maybe it is a chassis or suspension issue? Is something loose? Broken?
