Here's a general outline of the process. This is not a complete, step-by-step guide. You will need a detailed repair manual specific to your Fiero's year and model for precise instructions and torque specifications. These manuals are available online and from auto parts stores.
Before You Begin:
* Safety First: Disconnect the negative battery cable before starting any work on the steering system.
* Gather Tools and Parts: You'll need a variety of tools, including sockets, wrenches, screwdrivers (including Torx), a steering wheel puller, possibly a special column-specific tool, and of course, the replacement steering column.
* Repair Manual: Obtain a factory service manual or a reputable aftermarket repair manual specific to your Fiero's year.
General Steps (This is a simplified overview):
1. Steering Wheel Removal: Use a steering wheel puller to remove the steering wheel. This often involves removing a retaining nut and using the puller to separate the wheel from the column shaft. Mark the steering wheel's position relative to the shaft before removal to ensure proper realignment.
2. Column Removal: This is the most challenging part. It involves disconnecting various components connected to the steering column, including:
* Wiring harness: Carefully disconnect all electrical connectors. Take photos or make detailed notes to ensure correct reconnection.
* Steering linkage: Disconnect the linkage connecting the steering column to the steering gear.
* Ignition switch: Remove the ignition switch and its associated wiring.
* Column shift linkage (if applicable): Disconnect any linkages for automatic transmission column shifting.
* Steering column mounting bolts: Remove the bolts securing the column to the vehicle's body. Access to these bolts may require removing parts of the dash or other interior components.
3. Column Replacement: Carefully install the new steering column, reversing the removal process. Pay close attention to the alignment of the steering shaft and ensure all components are properly connected.
4. Reconnection: Reconnect all electrical components, linkages, and mounting bolts.
5. Alignment and Testing: Reconnect the battery and carefully check for proper steering operation. Make sure the steering wheel is straight when the wheels are straight. You may need to make slight adjustments.
Important Considerations:
* Airbag: If your Fiero has an airbag, you'll need to handle it with extreme caution. Consult your repair manual for specific instructions on disconnecting and reconnecting the airbag system. Improper handling of an airbag can cause serious injury.
* Ignition System: The ignition switch is a crucial component. Ensure it is correctly installed and functioning before driving.
* Torque Specifications: Always follow the torque specifications in your repair manual when tightening bolts. Over-tightening can damage components.
* Professional Help: If you are uncomfortable with any part of this process, it's strongly recommended to seek professional help from a qualified mechanic.
This overview provides a general idea of the process. The exact steps and difficulty will vary depending on the year and model of your Pontiac Fiero. Always refer to a detailed repair manual for your specific vehicle before attempting this repair. Failure to do so could lead to damage to your vehicle, injury, or even death.
