Can someone please explain how to replace the steering column bearings in a 1996 Ford Bronco (tilt wheel, air bag)? I've got it down to the cast aluminum housing but can't figure out how to the get to the bearings. Every book I've looked at doesn't give a diagram, pictures or instructions they only say to take it to the dealer. I hope someone can help my out.

p.s., this is my first post here and hope I'm in the right place to post a question. Thanks in advance for your help.
