1930 Model A Tie Rod Loose

[Wascator]

Hi, just got a nice A; noticed the right-hand tie rod end has too much movement. I noticed there is no cotter pin in the end, and the end plug seems screwed in pretty far. The driver’s side has no looseness and it has a cotter pin.
I need to know how to inspect the joint: how to inspect the ball, mostly. I know the other parts are replaceable.
