Removing the spare tire from a 2018 Ford F-150 is a straightforward process, but understanding the specific components and safety protocols ensures the task is completed efficiently and without damage. This guide provides a detailed walkthrough for owners who need to access the tire for replacement, storage, or maintenance purposes.
Locating the Spare Tire Assembly
The 2018 F-150 typically stores the spare tire vertically against the rear axle housing, underneath the truck bed. To locate it, you will need to access the rear of the vehicle and look for a cylindrical assembly bolted to the frame. This unit consists of the tire itself, a mounting bracket, and a specialized locking mechanism that secures it to the vehicle.
Required Tools and Safety Precautions
Before beginning, gather the necessary tools to apply proper force safely. You will typically need a breaker bar and a socket set that matches the lug nut size, which is often 1/2-inch. A torque wrench is essential for reassembly to ensure proper clamping force. For safety, always wear gloves to protect your hands and ensure the vehicle is parked on a level surface with the parking brake engaged firmly before starting any work.
Removing the Rear Wheel Cover
Many 2018 F-150 models feature a plastic wheel cover or cap on the spare tire that conceals the locking nut. This cover is often secured with plastic clips or snap-fits. Carefully pry it off using your fingers or a plastic trim tool to avoid scratching the paint. Once removed, you will expose the locking nut that secures the entire assembly to the vehicle.
Disconnecting the Locking Mechanism
The spare tire on this model year utilizes a locking cable system connected to the truck's anti-theft system. Before you can remove the tire, you must disconnect this cable. Locate the cable end near the locking nut and release the tension by pressing the release tab or using a pair of pliers to compress the spring mechanism. Securing this cable out of the way prevents it from snapping back or interfering with the tire removal.
Lug Nut Removal and Tire Extraction
With the locking mechanism released, use the breaker bar and socket to loosen and remove the lug nuts completely. Once the nuts are off, carefully maneuver the tire and bracket assembly forward and downward. The assembly is heavy and awkward, so support it securely to prevent it from falling and causing injury or damage to the truck bed lining.
Inspecting the Components
With the spare tire on the ground, take the opportunity to inspect the mounting bracket for rust or cracks. Check the tire for proper pressure and any signs of dry rot, which is common on older rubber regardless of mileage. If you are storing the tire, wrap it in a protective cover to shield it from dust and moisture.
Reassembly and Torque Specifications
When reinstalling the spare, reverse the process by lifting the assembly into place and hand-threading the lug nuts. It is critical to tighten the lug nuts in a star pattern to ensure the assembly seats evenly. Finally, use a torque wrench to tighten the nuts to the manufacturer's specification, typically around 100-120 lb-ft, to guarantee safe driving conditions.
