Hydro Assist Saginaw Chevy Box Problem

Hey everyone,

Had a customer send me a Saginaw steering box from a 1997 Chevy 1500 Truck, I broke it down , replaced all seals, tapped it and reassembled it. UPS got it back to him today, he tossed it back on and I have the following problem:

This is without the ram attached, and with the fittings at the box capped.


"The steering seems to want to turn to the left. When I
turn the wheel, it turns to the left EXTREMELY easily. In fact, it's so
easy that if I get a little momentum behind it, it spins rapidly all the
way to the stop. Turning right is a different story. It takes slightly more effort than before I removed the steering box and stops suddenly when pressure is released (normal operation). "

I rebuilt the box with the power master seal kit, installed the balls into the worm gear by properly alternating them, liberally coated everything with power steering fluid and put it all back together. I'm just now starting to brain storm over what could be causing this, and need all the ideas you guys have.

I think the fitting on the lower port (which has high pressure when turning right) may be causing slight interference into the fluid flow, and that could be why he is experiencing more resistance. Im gonna get him to loosen it a thread or so, and see if he still has the same problem.

I am at a loss on what could be causing the left situation however.

I told him to jack the truck up, and turn from lock to lock with and without power and let me know what he notices as far as ease of turning etc.

I need some input guys!

I agree, sounds like the lines are backwards.

The lines from the power steering pump to the box are backwards?

He said the box is capped at the ports and the ram is not hooked up

on my brothers truck we had to cut a bit off the end of the fitting so it would not block the port. was not a newer box, but might be similar

I am leaning towards the fitting blocking the port as well - however, I did not hit the vain dead on. Ill have him take a look at it, try a new shallower fitting, and see what happens. Hopefully that will cure it, if not no big deal, Ill just send him a new box at my cost. Thanks guys.
