However, I can give you a *general* overview of the steps involved. Remember, this is NOT a substitute for a proper repair manual:
1. Safety First:
* Disconnect the battery: This is crucial to prevent accidental airbag deployment or short circuits.
* Wear safety glasses: Small parts can fly, and you'll be working with sharp objects.
* Have the right tools: You'll need various sockets, wrenches, screwdrivers (possibly Torx), possibly a puller, and potentially a special tool to remove the steering wheel.
2. Steering Wheel Removal:
* Locate the steering wheel retaining bolt: Usually located in the center of the steering wheel, hidden behind a cover.
* Remove the retaining bolt and nut: This will require the correct socket and often a special tool to hold the steering wheel stationary while you loosen the bolt. If the steering wheel has an airbag, there are additional steps involved (see your manual).
* Carefully remove the steering wheel: Note its position before removal – you'll need to reinstall it exactly the same way.
3. Column Shroud Removal:
* Locate and remove the lower shroud: This usually involves removing screws or clips around the steering column base.
* Access the upper shroud: This might involve removing trim pieces or other components in the dashboard.
* Carefully remove the upper shroud: This allows access to the steering column components.
4. Column Disassembly (This is highly dependent on your specific model):
* Disconnect the wiring harness: This includes various connectors for the turn signals, horn, cruise control, and other functions. Take pictures or label each connector before disconnecting.
* Remove the ignition switch: This is usually held in place by screws and possibly a retaining clip.
* Disconnect the shift linkage (if applicable): If the column is linked to the automatic transmission shift, disconnect the linkage.
* Remove the column shaft: This might involve removing clamps, bolts, and possibly using a puller.
* Remove the lower bearing: This is often the most difficult part and might require specialized tools.
5. Reassembly:
Reassembly is essentially the reverse of the disassembly process. Ensure all components are properly seated and all wiring connectors are securely attached. Consult your repair manual for torque specifications for all fasteners.
Again, this is a very general overview. Attempting this without a repair manual is strongly discouraged. Improper disassembly can damage your vehicle's electrical system, airbag system, steering mechanism, or even cause injury. A repair manual will provide detailed diagrams, torque specifications, and crucial safety warnings specific to your 1993 Buick Century. If you're not comfortable with this level of car repair, take it to a qualified mechanic.
