Here's a general overview of the process. Remember this is NOT a substitute for a proper repair manual:
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the truck from rolling.
* Lug wrench: To remove the wheels.
* Socket wrench set: With various sockets and extensions to reach the shock mounting bolts.
* Wrench set: May be needed for some bolts.
* Torque wrench: Crucial for tightening bolts to the correct specification (found in your repair manual).
* Shock compressor (optional but highly recommended): Makes compressing the shock spring much safer and easier. Trying to compress the spring by hand is dangerous.
* Penetrating oil (like PB Blaster): Helps loosen rusted or seized bolts.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the truck using the jack and securely support it with jack stands. Remove the wheel.
2. Remove the Old Shock:
* Locate the top and bottom shock mounting bolts. They are usually nuts and bolts, but could be different depending on your specific truck.
* Spray penetrating oil on the bolts if they are difficult to turn.
* Use your sockets and wrenches to carefully remove the bolts. The shock should then come free. This may require some maneuvering and overcoming spring pressure. This is where a shock compressor is invaluable.
3. Install the New Shock:
* If using a shock compressor, follow its instructions carefully. Compress the new shock's spring to roughly match the length of the old shock.
* Line up the new shock with the mounting points. It might be helpful to have someone hold the shock in place while you tighten the bolts.
* Tighten the bolts to the torque specifications specified in your repair manual. Using the incorrect torque can damage the shock or its mounts.
4. Repeat: Repeat steps 2 and 3 for the other shock on that axle. It is often recommended to replace shocks in pairs (both on the same axle).
5. Lower and Test: Lower the vehicle, remove the jack stands, and reinstall the wheel. Test the suspension by bouncing on each corner of the vehicle. Make sure there is no binding or unusual noises.
Important Considerations:
* Different Models and Trims: The exact procedure may vary slightly depending on your specific F-150 model and trim level (4x2 vs. 4x4).
* 4x4 vs 2x4: 4x4 trucks often have more complex suspension systems.
* Spring Pressure: The coil springs in the suspension store significant energy. Never work under a vehicle supported only by a jack. A shock compressor is highly recommended to avoid injury.
Again, this is a simplified overview. Always consult a repair manual specific to your 2004 Ford F-150 SuperCrew before attempting this repair. If you're not comfortable performing this work yourself, take your truck to a qualified mechanic. Improper installation can lead to serious problems.
