Here's a general outline of the steps. This is NOT a comprehensive guide and should not be solely relied upon. Consult a repair manual specific to your 1986 Ford F-250 for detailed instructions and diagrams. A Haynes or Chilton manual is a good investment.
1. Disconnect the Battery: Disconnect the negative (-) battery terminal.
2. Steering Wheel Removal: Remove the steering wheel. This typically involves using a steering wheel puller tool. Note the position of the wheel relative to the column before removing it to ensure proper reinstallation.
3. Column Components: Disconnect the various components connected to the steering column:
* Wiring Harness: Carefully disconnect all wiring harnesses connected to the column. Label or photograph the connections to aid in reassembly.
* Ignition Switch: Remove the ignition switch. This often involves removing screws and possibly a retaining clip.
* Turn Signal Switch: Disconnect the turn signal switch.
* Cruise Control (if equipped): Disconnect any cruise control components.
* Shift Lever (if column-shifted): Remove the column-mounted shift lever mechanism if applicable.
* Steering Column Coupler (Universal Joint): This is a crucial step and may require special tools. The coupler connects the steering column to the steering gear box. You'll need to disconnect this carefully, often requiring the removal of bolts or clamps.
4. Column Support Brackets and Bolts: Locate and remove the bolts and brackets holding the steering column to the vehicle's dashboard and firewall. There are usually several bolts securing the column in place.
5. Lower the Column: Carefully lower the steering column. There may be some obstructions, so work slowly and methodically.
6. Removal from Vehicle: Once all connections are disconnected and the column is free from its mounting brackets, carefully remove it from the vehicle.
Important Considerations:
* Safety: Work in a well-lit, clean area. Use appropriate safety glasses and gloves.
* Torque Specifications: Pay close attention to torque specifications for all bolts and fasteners. Over-tightening or under-tightening can damage components.
* Alignment: After reinstallation, the steering wheel and column must be properly aligned. Improper alignment can lead to dangerous driving conditions. Professional alignment may be required.
* Special Tools: You will likely need special tools for this job, including a steering wheel puller, various sockets, and possibly a coupler separating tool.
* Professional Assistance: If you are not comfortable performing this task, it's best to seek professional assistance from a qualified mechanic. The consequences of improper installation can be severe.
This is a simplified overview. Always consult a repair manual specific to your vehicle for the correct procedure. Attempting this without the proper knowledge and tools can result in damage to your vehicle and potential injury.
