I have a Lazear Unlocking Steering Wheel. The steering is quite loose and I would like to fix it and most of the sloop is in the gears. The center nut cover is a very good fit and there are no notches to get anything to pry it out. I looked at the patent and they take pride in the fact that it snaps in to a grove making it very hard to remove it to defeat the unlocking so you can drive off with the car. (My car was owned by a policeman when new or just a year or two old). I do not have the key but I do have the key numbers for what it's worth. Anyone know how to remove the wheel?
I see that you're not terribly far from Ann Arbor. Contact Vogel's lock shop and see what they might be able to do with the key number & the brand of lock, if that's indicated also. They have a lot of old information and old blanks. They made a key for the steering lock in my touring many years ago with no more information than what you've got.
Steve, If the top cover has a small hole in it around the edge where the threads would be, this is where it would be staked so that it couldn't be unscrewed from the column. The pin needs to be removed to allow it to be unscrewed from the column. Some times it can be pushed out from underneath (back through that little hole), but more often it will need to be driven out the bottom which will damage the lower threaded base. It was designed to be locked and theft proof and not taken apart. Steve
You sure the slop is in the gears under the steering wheel? Sounds more like pitman arm to me.
