Just to check, you did completly remove the bolt right? The rack has a groove in it so it wont come off when the bolt is still in there. If you did, you'll need to pull the column out a bit, assuming its a MK2/3 Golf or Corrado or something:
1. Take the driver side dash undertray out, only a few screws
2. Remove the ign lock housing lower trim, 2 screws
3. Disconnect all the plugs to the stalks & ign switch
4. Remove the allen bolt from the bottom of the ign lock
5. Grab steering wheel and pull, column should come out a bit, wigglew the UJ in the bay and at the base of the column till it releases from steering rack
