Kubota B7800
I have no power steering, weak and Shakey loader, and 3 point. Also low power in low won't even go on high. Is it my pump or could it be something else?

I would perform the simple things first before condemning a pump.

1) have you verified system is full of oil?
2) when was light time filters were changed?
3) Has suction screen been cleaned? I believe that tractor has one but not not positive.
4) If rubber hose on pump inlet check for cracks in the hose. Also check if any clamps are lose.

Items 1 - 3 are mostly suspects.
Other possibility depending on location and temps is water is system has frozen blocking suction screen.

Check for air in the system.

What do you mean by that?
I mean I read a lot of Tom Clancy novels and when your submarine is cavitating, it makes noise that can be detected by enemy destroyers.
