have been experiencing a pop sound underneath sounding like thin metal being released from a vacum, has anyone heard of this, could it be coming from the gas tank or oil pan, no performance issues other than loosing 100 miles on a tank of gas, have a rear pinion seal leak, not sure if related, also light on four wheel drive buttons are going in and out but it is not dropping into auto or 4 wheel. thanks.
