I've posted a teardown of the steering column below.
If the column is loose (sloppy) at the point of swivel, there is a common problem with the (3) screws holds the housing to the column comming loose. This is number 29 on the diagram, and the screws have torx heads. You'll need to tear it down to this point and then the loose screws are obvious, I also recommend putting Loctite on the threads to prevent future loosening.
