Re: Steering wheel center part is loose and wobbly

The series of photos below may help illustrate the operation of the telescoping column. I had mine apart when I was looking for a very irritating "squeak" when I turned the steering wheel. And also just because I like to take stuff apart to see how it works...
Anyway, the photos show the sequence of reassembling the steering wheel. The first two photos show the column scoped "IN" and then scoped "OUT". The horn rotating contactor ring goes on first, followed by the big spring. This spring is what makes your steering wheel pop up when you unlock it. Next, the steering wheel mates with the splined section of the shaft, then the metal "tang washer" goes on top of the steering wheel hub, and both of them are retained by a large nut. The black locking ring that positions the scoping section fits on the smaller threaded shaft at top center of the column, and the mounting hole indexes on the flat side of the circular piece. When you turn the locking ring, you are only turning the center portion of the shaft, which then moves something (?) down inside the column to lock it in place.
You can see that it does not matter how much you tighten the nut holding the black locking ring - this does not affect it's function.
The really sharp-eyed members will note that (when taking these photos) I initially installed my steering wheel with the spokes pointing the wrong way (up, toward the windshield, instead of down). 
If it's possible to do something wrong...I will. I often learn my best lessons (sometimes painfully) by Trial & Error.
