This doesn’t look right

if a mechanic said it's ok, then it's ok.

 

Can tell exactly nothing with your video, you have to watch the pitman arm, not go by how far you can turn it.

 

This is going to be a long year.

Don't they train the free wheel play limits anymore at the steering wheel inside the cab?

 

Sounds about right...

Go to a truck dealer and try it on any NEW truck for a surprise

 

Am I missing something here? I thought you tested play with the engine off so you’re not getting fooled by the power steering assist. Someone reply maybe I’ve been doing it wrong this whole time.

 

Sit in cab engine off, try to move steering wheel. It should only do a little bit of movement. Not very much at all.

Nothing making too much noises while doing it either. Drive off.

 

Even with the engine off, you can be moving the pitman arm, even more so if you are using the steering wheel.
Move the steering shaft back and forth while watching the pitman arm, the free play is only how much it moves before the pitman arm starts to move even a minute amount. If you can detect any movement at all on the pitman arm, you are past the point of freeplay.
