power steering not coming out of return

I'd say replace the unit .

Steering racks internal valves are stuck, only to fix it is to replace the rack itself, and get a long rack not a short rack, hopefully the pump isn’t damaged due to the back pressure. Make sure you flush the pump really good before putting in the new rack assembly.

thank you for your answer it was very helpful . I was thinking the rack was damaged ; but i wasnt sure how and to what degree but what you said makes sense. So once again thank you
