When i shut off the truck most of the PS fluid leaks out.
Any 1 have any ideas pump,hose,rack?

Plz help

 

Did you check all of those things? I would think that it would leak more when the truck is running.

 

could be a seal in the rack, when the pressure is off the seal, it retracts and fluid goes out past it or a hose, but usually if its a hose it leaks when running. also check your resevoir for cracks because when it runs it is flowing through the system and not sitting long enough. could be the pressure preventing the crack from spreading, sounds weird but it happens
