The front feels like loose when driving. on 1997 Chevrolet S10

I had it checked and everthing seems tight there is no play but when I drive there are times when feels like it is floating. This started after I disengaged from 4 wheel drive, a few weeks ago, I have tried putting it back in 4 wheel drive but nothing helps.

I would have all steering parts inspected. Maybe broken sway bar, bad steering box, etc.
