You have an air lock in the ram. Jack the jeep up so the tires are off the ground. with the key on and the engine off and turn it left all the way and right all the way at least ten times. Check fluid to see if it foamy if so let it set until until its not foamy and then do the turns again. Mine took a several cycles to get all the air out.
Then it must be your steering box. It was drilled wrong allowing fluid to flow into the ram. Sounds like you will need a new steering box.
curious of this as well, also if it is working, how happy are you with the system?
