The two pins pictured post #5 are not brass unless they've been replaced. Oem is steel and I've never seen one worn to the the point of creating noticeable steering slop

Most often the issue is a worn gimbal ring, steering shaft, tiller arm, or all three. Second most often cause is a worn steering cable or helm and in this case the steering system itself is usually quite stiff even with power steering

Yes...the pinch bolt, tiller arem and gimble pin are all tight no slop...if you pinch up on the video and look closely there is ALOT of slop where the steering cable links to tiller arm at both pin points, the pins just look brass in color.

I see the video link now and have watched it

That is not a lot of slop, especially with the engine not running/power steering actuator disengaged. There is a bit of free play in the design of the system to allow for free movement/less risk of binding during operation and yours looks normal

Feel free to replace the pins, it will not alleviate any free play you are seeing

What exactly is that piece called? The piece with the pins at end of steering ram.
Ayuh,... That's the working end of the P/S actuator,......

Some of that slop is then P/S hyd. valve, that tightens up when the pump is running,...
That's how it knows whether to push, or pull,.....
