1999 Plymouth Voyager Replacing steering box

We have been having problems with power steering and popping in the steering box. My husband is trying to remove the steering box to replace it and we can't figure out how to get it off without cutting the connecting lines. How do we remove the box? We cannot afford to take it back to the repair shop since we just paid them $320 to replace the power steering pump and belt assembly that caught on fire! Please Help! They want to charge us another $600-$700.
