The rear air bags devolop leaks. You can spray them down with soapy water turn the key on and shift into reverse. Then sit on the rear bumper. You will hear the pump run when it shuts off. Lay under and look at the shocks if there are leaking youll see bubbles. If no bubbles its a line like j and n said.
