78 ln9000 power steering

Hello. I have a 1978 ford Ln9000. Power steering pump keeps forcing fluid back out the top. Do you think this is caused by bad seals and power assist cylinder? The power steering pump isn't whining. Thinking maybe fluid is blowing right past seals it cylinder. I figure I asked for some expertise.

    Is it hard to steer/turn? Normally a TRW power steering box was used on LN, LT, LTL's.

    Is the pump belt driven or direct drive?
