Look underneath where the hoses go into the rack, do you see any signs of fluid leaking at that spot? There is a service bulleting for this. Does the power steering pump whine? any leaks on the ground?

Customer: replied 8 months ago.
No rack . Steering box. No leaks fluid level is good.

the pump is whining
Expert:  Dan replied 8 months ago.

Sorry I mean to say steering gear. Lift front wheels off ground, with engine off, turn wheel from lock to lock 10 to 15 times. The incline will help get any air out of the lines. It can take a while to get all the air out.

Did that. Also ran it with tires in the air. Was good. Put it on the ground and steering was still tight.

Did the pump come with a new reservoir?

Customer: replied 8 months ago.
No
Expert:  Dan replied 8 months ago.

Make sure the reservoir is clean, the screen could be clogged causing this problem.

In the reservoir

Customer: replied 8 months ago.
Did not see one.
Expert:  Dan replied 8 months ago.

I would keep trying to bleed it sounds like you still have air in the system.
