You cannot compare the two pictures unless the ram on both pictures is extended the same amount. The hoses flex as the ram moves.
And that is the primary issue with the stock power steering system. 2 (of 4) hoses move every time you turn the wheel. The other components do their best to leak, too, but those hoses are a common failure point, especially today, when no one can make anything of quality anymore. @4-vettes , I think, had a set custom made by a hydraulic shop. That's probably the best solution if you want to keep the 4-hose system.
The Borgeson steering box eliminates the two hoses in motion. Manual steering eliminates all 4.
So... I was at a car show and had my power steering go out as I was trying to back into a space.. looked under the car and saw a leak that I found out started a ways back while to my spot... so I nursed it home and this morning I filled the fluid back up and jacked up the car... what I saw is in the pic.. Now this part is only like 2 months old... soooo, my question is do I rebuild it or just get another one?? also after taking it out and replacing it do I have to go through the whole process of balancing it with the control valve or just slap it in and make sure I have no air in the system... Thoughts appreciated...

That's not true, the assist cylinder and the control valve are both attached to the power steering relay rod and move together. The power steering relay rod moves parallel because the pittman arm and idler arm keep it parallel.
Wheels straight ahead.
Wheels hard to the right... I should have painted the control valve before installing it but hindsight is 20-20.
Edit: the only movement I can measure is the power steering relay rod gets about 1/8" closer to the power assist cylinder measured at the position where the left tie rod is attached and the square part of the power assist cylinder. This is due to the arc of the pitman arm and the idler arm and that the end of the power assist cylinder rod is fixed at the frame.

JT,
thanks for the pics and info... Now after working on it I surmise it was the hose leaking and not the slave cylinder so I guess I learned something... In any case once I get the new hoses I'll swap them in as mine look like a leak waiting to happen... and I grease the the new cylinder since it didn't really have any in there...

Do not use anything stronger than a small hand greaser.

Just don't grease the control valve zerk. I know it looks like you should, but don't do it. That can cause a control valve failure if it gets over greased.

thanks for letting me know that... When I get back under the car I was gonna do that also..
