2001 E320 4M 'tie rod'?

[grateful1]

Ok. the local oil change place rotated my tires and the kid mentioned a very loose 'tie rod' - it's in quotes because I didn't look at it.
I believe something is loose...as they don't fix stuff like that, it was just nice of him to notice and say something!

So...what's the best way to check this out?

Thanks!
