If the spare is under the truck:
1. Locate the spare tire: It's usually located under the truck bed, often accessed by a panel or cover. This access panel might be located towards the rear of the truck bed, often requiring you to lower the tailgate.
2. Access the spare: This usually involves releasing a retaining strap or bolts holding the spare in place. There might be a winch-type mechanism or a simple release latch. Carefully inspect the area for any levers, knobs, or fasteners. Consult your owner's manual if you're unsure.
3. Lower the spare: Once the retaining mechanism is released, carefully lower the spare tire. It can be heavy, so be prepared to support its weight. Some models use a winch to assist with this.
4. Remove the spare: Once the spare is lowered, carefully remove it from its compartment.
If the spare is in the truck bed:
This is much simpler. The spare tire is simply sitting in the truck bed. You just need to lift it out. Be mindful of its weight.
Important Considerations:
* Owner's Manual: Your 2004 F-150 owner's manual will have the most accurate and detailed instructions for removing your specific model's spare tire. This is the best place to start.
* Safety: Spare tires are heavy. Ask for help if you need it to avoid injury. Wear gloves to protect your hands.
* Tools: You might need basic tools like a wrench or socket depending on the type of fastening mechanism securing the spare tire.
* Jack and Lug Wrench: Remember that you'll also need a jack and lug wrench to actually *use* the spare tire if you're replacing a flat.
