Just keep pumping. You will soon find the leak. Really, this is not the right answer. If the car is constantlly dropping, there is a leak either into the sphere or out of the sphere. Try dislodging the plastic cover on the knuckle strut and see if there is any moisture. Is one corner hard when you bounce it? If it is then the sphere is flat and continually pumping it up will only do further damage.
