Hi
Tee into a steering line and with the wheels off the ground turn to stops and check pressure, then do the same with wheels on the ground.Try to do one steering cylinder at a time also and check them by plugging the lines to the one cylinder then the other because sometimes what looks good is realy leaking by under high pressure also.
Have you checked the power steering fluid?
