@dkerby - I think the best way to teach the pivot's role in swinging the left arm is to swing the club left arm only.

Keeping the head stationary, start by slowly swinging the club a few feet back and forth. Gradually lengthen until you are making repeated full rhythmical swings.

Now try to make the club go faster through impact. It will immediately become evident how to use the pivot to accelerate the club. You simply cannot do it without harnessing the pivot and the left side to power the flail - loading and unloading the "gyroscope".

After getting used to that, have him hit shots left arm only with a sand wedge. That will teach him how to add the all important "downward" element of impact.

As far as the pain in the right hip goes, it might be swing related. I had pain in my right hip because I tried to immobilize it to combat a slide. When my pivot improved (and I allowed my right hip to clear) I had no more pain, and no more "over the top".

Anyways, these are my personal experiences, not tried and true teaching techniques as I'm simply an amateur. Hope it helps anyways!
