Converting a 1987 Ford F150 from 2WD to 4WD: A Comprehensive Guide
Converting a 1987 Ford F150 from 2WD to 4WD is a significant project that enhances the vehicle's capabilities and off-road performance. This article provides a detailed guide on the conversion process, essential steps, and considerations to ensure a successful transformation.
Understanding the Conversion Process
Converting a 1987 Ford F150 from 2WD to 4WD is a complex project that requires careful planning, the right components, and skill. Understanding the different parts and the sequence of installation is crucial to achieving a reliable and functional 4WD system.
Gather Necessary Parts
The conversion process involves several key components:
1. 4WD Front Axle
Selecting the appropriate 4WD front axle is essential. You can source one from a compatible 4WD F150 or other compatible models.
2. Transfer Case
Choose a transfer case that matches your truck's transmission. This component is crucial for distributing power to all wheels.
3. Driveshafts
Install new driveshafts to connect the transfer case to the front and rear axles.
4. Transmission Adapter (if needed)
Some older trucks may require a transmission adapter to fit the new transfer case.
5. Suspension Components
Install 4WD-specific springs, shocks, and possibly control arms.
6. Steering Components
Replace the existing steering box and install a new pitman arm and steering linkage.
7. Brake Components
Ensure you have the correct brake calipers and rotors for the 4WD front axle.
Prepare the Truck
Before starting the conversion, you need to prepare your truck:
1. Lift the Vehicle
Lift the front of the truck using a jack and jack stands. Ensure the truck is securely held in place.
2. Drain Fluids
Drain the transmission and differential fluids to prevent spills during the conversion.
Remove 2WD Components
Disassemble the 2WD components:
1. Remove the Front Suspension
Disconnect and remove the front suspension components, including control arms and shocks.
2. Remove the Front Axle
Disconnect and remove the existing front axle.
3. Remove the Transfer Case (if applicable)
Separate the existing transmission and transfer case if they are integrated.
Install 4WD Components
Begin the installation process:
1. Install the Front Axle
Position and secure the new 4WD front axle.
2. Install the Transfer Case
Attach the transfer case to the transmission, ensuring all connections are secure.
3. Install New Driveshafts
Connect the driveshafts from the transfer case to the rear and front axles.
4. Install Suspension Components
Install the new 4WD suspension components, including springs and shocks.
Final Checks
Complete the conversion by performing final checks:
1. Check Fluid Levels
Refill the transmission, transfer case, and differentials with the appropriate fluids.
2. Test the System
Test the 4WD system in a safe environment to ensure everything is functioning properly before hitting the road.
Considerations
Several factors should be considered during the conversion:
1. Compatibility
Ensure all parts are compatible with your specific model and year to avoid compatibility issues.
2. Skill Level
This project is complex and may require advanced mechanical skills. Consider consulting experienced individuals or hiring a professional if unsure.
3. Tools
You will need a variety of tools, including wrenches, sockets, jacks, and possibly a lift, to ensure the conversion is done safely and effectively.
Conclusion
Converting a 1987 Ford F150 from 2WD to 4WD can be a rewarding project but requires significant work and attention to detail. Always prioritize safety, and consult with experienced individuals if needed. By following this comprehensive guide, you can transform your truck into a more capable and versatile 4WD vehicle.
