I drive a 2007 GMC Savanah 3500 cube van (box truck) for work, and we have had repeated power steering leaks. The hose has been replaced, but it still leaks occasionally, though not as much. When the wheel is cranked all the way to the right or left it makes a rough grinding noise, but the steering functions fine otherwise. Would a liquid seafoam cleaner/liquid polymer be worth trying, or does this sound like another issue entirely? Thank you.

Do not put seafoam in your power steering
we have had repeated power steering leaks.
use a leak detection kit to find out where the leak is coming from
makes a rough grinding noise
sounds like the pump is wearing out.
Did you check for play in the pulley?
