Your problem is with the tilt. You'll have to pull the wheel, lock plate, disconnect signal plug underneath and pull signal switch out past the shaft. Then you'll be able to pull the tilt pins. You can do that with a wood screw and a pair of dikes. That's where you'll find the knuckle on the shaft. It's held in by a four bolt flange. They're star bolts, make sure you've got a set of star sockets. Tighten them up and reassemble. It's cake, really.

Oh, and you'll have to relieve the tilt spring. If I'm not mistaken, you push in with a flat head screw driver (it's a square hole) and quarter turn to the left.

Having a sentence that includes wood, screw, and pair of dikes makes any post a good read

check this out and see if it relates. Usually they just get floppy at the tilt knuckle. I'm not sure if your 360 degrees of movement is referencing that.
