1. Parts Acquisition: This is the most crucial step. You'll need a complete power steering system specific to a 1968 Chevy pickup (or a compatible year). This includes:
* Power Steering Gearbox: This is the heart of the system. Make sure it's the correct ratio for your application. Finding a used, rebuildable unit might be more economical.
* Power Steering Pump: Must be compatible with your engine and the gearbox.
* High-Pressure Hose(s): These connect the pump to the gearbox. These will likely need to be custom made or adapted.
* Low-Pressure Hose(s): Return hose from gearbox to reservoir.
* Reservoir: Holds the power steering fluid.
* Steering Shaft: May need to be modified or replaced to accommodate the power steering gearbox.
* Steering Linkage: This connects the steering gearbox to the steering knuckles. You'll likely need to modify or replace existing components. This is highly dependent on the type of steering box used.
* Brackets and Mounts: Necessary to securely attach the pump and gearbox to the engine and frame.
* Power Steering Fluid: The correct type is essential.
* Belt: To drive the power steering pump.
* Pulley: May need to be changed to accommodate the power steering pump.
2. Preparation:
* Thorough Inspection: Before you start, carefully examine the existing steering system. Take pictures and notes to aid in reassembly.
* Removal of Existing Components: Disconnect the steering linkage, steering column, and other necessary parts to make room for the power steering components.
* Cleaning: Clean the engine compartment thoroughly to prevent debris from entering the new system.
3. Installation:
* Gearbox Installation: Mount the power steering gearbox to the frame. This often requires drilling and potentially welding mounting brackets.
* Pump Installation: Mount the power steering pump to the engine. This usually involves using existing holes and/or adding new mounting points. Belt routing will need careful consideration.
* Hose Installation: Connect the high-pressure and low-pressure hoses securely. Pay close attention to proper routing and clamping. Leaks are a major problem if these are improperly installed.
* Steering Shaft Adaptation: Modify or replace the steering shaft to work with the new gearbox.
* Steering Linkage Installation: Install the steering linkage, making sure all adjustments are made correctly for proper caster and camber. This is often the most challenging part, requiring precise measurements and adjustments.
4. Fluid Filling and Bleed:
* Fill the Reservoir: Add the correct type and amount of power steering fluid.
* Bleed the System: This is crucial to remove any air bubbles from the system. There are specific procedures for bleeding power steering systems.
5. Testing and Adjustment:
* Test Drive: Test the power steering system carefully, checking for leaks, proper operation, and unusual noises.
* Alignment: After installation you will almost certainly need a professional wheel alignment.
Important Considerations:
* Safety: Power steering installation involves working with potentially hazardous components and fluids. Always follow safety precautions.
* Expertise: If you lack experience in automotive repair, it's highly recommended to seek professional help.
* Manuals: Obtain a repair manual specific to your 1968 Chevy pickup. This will provide detailed instructions and diagrams.
* Parts Compatibility: Ensure all parts are compatible with your vehicle's engine and chassis.
This is a simplified overview. A successful power steering installation requires meticulous attention to detail and a thorough understanding of automotive systems. Improper installation can lead to poor handling, leaks, component failure, and even accidents. Again, seek professional help if you're not comfortable performing this task.
