Quoting Removed, click Modern View to see

Not a squeal, but more like slurping...like air and fluid are passing by a small opening.

While I was waiting for a reply to this post last night, I thought I would try a few things:

1. First, attached a gauge and got around 100 psi of the the pressure side and fluid would foam and move out the steering column seal below the steering wheel.

2. I removed the pump and stretched out both springs in the relief valve a bit, put back together and got pressure of 500 psi when turning left or right and holding and no fluid came out the steering column.

3. Took pump off again and noticed it was pretty warm to the touch from number 2 above, then tried to stretch springs more, put back and got 100 psi pressure and fluid out steering column.

When I stretched springs under number 3 above, the springs didn't stretch straight. I put it back together anyway, but I think the crooked springs may be inhibiting the relief valve from closing.

I'll look into your other suggestions...I need to read the manual to understand the stuff you said...I just thought I would post what I did in the meantime.
