The power steering in my Express is having issues.
Last year it stopped working and a fluid flush solved that. Now it is half assed working and a fluid flush has not solved it completely. Is there a way to check the pump pressure maybe to see whats going on? I don't want to throw parts at it to solve it.

The steering on my 06 3500 started working so poorly awhile back that I had to use both hands to haul it around a slow corner in town at low RPM. A pump fixed mine, there is a TSB (technical service bulletin) on it.
