The other posters are right on with getting the bearing kit from ford.
After Market Shaft:
1992 - 2004 Ford F-150 Upper Steering Shaft - AM Autoparts
Hope the pdf below helps. Included is a disassembly pic from a '92 crown vic. the exploded view and the Mitchell On Demand page on the column. I especially like how Mitchell just says refer to x-ploded digram for the rebuild. What a bunch of dorks!
I'm looking for a detailed disassembly procedure myself. Please let me know what you come up with.
