Removing factory fasteners

Identify the Fastener Type: Begin by identifying the type of factory fasteners securing your plastic fender flares. They can be plastic tabs, simple screws, or specialized fasteners. Understanding the type of fastener you are dealing with is essential for choosing the appropriate removal technique.

Gather the Necessary Tools: Depending on the fastener type, you may need different tools for removal. For plastic tabs, you might require a flat-head screwdriver or a similar tool to pry them loose gently. If there are screws, ensure you have the correct screwdriver type, such as a Phillips-head screwdriver, to match the screw head. For specialized fasteners, refer to your vehicle's manual to identify the specific tools needed for removal.

Remove the Fasteners: Start by carefully prying loose any plastic tabs using a suitable tool. Be gentle to avoid damaging the tabs or the surrounding area. For screws, use the appropriate screwdriver to unscrew them in a counterclockwise direction. Again, be cautious not to strip the screws or damage the surrounding surface. If your vehicle has specialized fasteners, follow the manufacturer's instructions for proper removal. Some fasteners may require specific tools, such as Torx screwdrivers or clip removal tools, so ensure you have the right equipment.

Secure the Removed Fasteners: As you remove the fasteners, it is essential to keep them secure and organized. Place them in a container or lay them out on a clean surface to avoid misplacing any parts. This step ensures that you have all the necessary fasteners for reinstallation or future use.

Inspect the Fender Area: Once the factory fasteners are removed, carefully inspect the area. Look for any fender support braces that may need to be relocated or adjusted. This step is crucial for ensuring the fender remains positioned correctly and securely attached to your vehicle. If necessary, consider seeking professional help from an experienced body shop for complex adjustments.

Follow Safety Precautions: Throughout the process, prioritize your safety and the protection of your vehicle. Wear safety glasses to shield your eyes from debris and potential projectiles. Additionally, consider using a mask or respirator to prevent the inhalation of dust or particulates generated during the removal process.

Remember, each vehicle is unique, so always refer to your manufacturer's instructions and seek professional advice if you have any doubts or encounter challenges during the removal process.

Marking bottom flare hole location

Marking the bottom flare hole location is a crucial step in installing fender flares on your vehicle. Here's a detailed guide on how to do it accurately:

Positioning the Fender Flare

Start by placing the fender flare against the vehicle's body, holding it steady in the desired position. Ensure the fender flare is securely held in place to avoid any slippage during the marking process.

Identifying the Bottom Hole

Locate the bottom hole on the fender flare. This hole will need to align with the corresponding point on your vehicle's plastic bumper. It's important to identify this hole accurately, as it will serve as a reference for drilling and attaching the flare.

Marking the Hole Location

Use an erasable marker to mark the point where the bottom hole of the flare aligns with the plastic bumper. Draw a small circle around this point to clearly indicate the hole location. Make sure the circle is centred on the hole to ensure precise drilling.

Verifying Alignment

Double-check that the marked hole location on the plastic bumper aligns perfectly with the bottom hole on the fender flare. Any misalignment can affect the overall fit and appearance of the flare. It is crucial to take your time during this step to ensure accuracy.

Marking the Frame Hole

If your vehicle's frame has existing holes, locate the one that corresponds to the bottom flare hole. Hold the fender flare in place and use your erasable marker to mark this frame hole location. Again, use a small circle to ensure you drill through the centermost point.

By following these steps, you will accurately mark the bottom flare hole location, ensuring a secure and proper installation of your plastic fender flares. Remember to take your time and double-check all measurements and alignments before proceeding with the drilling and attachment process.

Drilling holes

Before drilling any holes, it is important to mark the locations where you will be drilling. Place the fender flare against the vehicle's body and mark the points where the holes on the flare align with the body. Use an erasable marker to mark the hole locations, ensuring that you mark with a circle to drill through the centermost point.

When you are ready to drill, attach a 1/4-inch (0.64 cm) drill bit to your electric drill. Create holes through the marked points on the fender flare and the vehicle's body, drilling directly through the center of each mark. Always use your marks as a guide to ensure accurate drilling.

After drilling the holes, you can proceed to attach the fender flare bracket using the provided hardware. Align the fender flare with the vehicle and attach the hardware into the drilled holes to secure it to the vehicle's frame. Follow the manufacturer's instructions as the exact hardware and steps may vary depending on the product.

It is important to note that drilling holes in your vehicle's body can be a significant modification. If you are unsure or uncomfortable with the process, it is recommended to seek professional assistance. Additionally, always wear appropriate safety gear and take necessary precautions when operating power tools like electric drills.

Attaching flare trim

Firstly, it is important to select the appropriate flare trim for your vehicle. Ensure that the trim matches the contours and size of your specific make and model. Some vehicles may have pre-drilled holes or specific locations for attaching the flare trim, so refer to your manufacturer's instructions or a professional for guidance.

Next, prepare the surface by cleaning and sanding the area where the flare trim will be attached. This step ensures that the adhesive will bond securely and smoothly to the vehicle's body. It is crucial to follow the manufacturer's instructions for surface preparation, as it may vary depending on the type of adhesive used.

Now, it's time to apply the adhesive. Some flare trims come with an adhesive backing, which you can attach by removing the protective tape and pressing the trim firmly onto the desired location. Ensure the surface is clean and dry before application. If your flare trim doesn't have an adhesive backing, you may need to use a suitable glue or adhesive recommended by the manufacturer.

For added security, consider using mechanical fasteners in addition to the adhesive. This may include plastic fasteners, U-clips, or screws, depending on the design of your flare trim and vehicle. Carefully align and attach the flare trim to the vehicle, following the manufacturer's instructions for any specific attachment points or procedures.

Finally, once the flare trim is securely attached, it is important to allow adequate curing time for the adhesive to ensure a strong and durable bond. Refer to the manufacturer's instructions for the recommended curing time and any post-installation care or maintenance.

By following these steps and seeking guidance from professionals or manufacturer instructions, you can effectively attach flare trim to your vehicle, enhancing its style and functionality.

Using plastic fasteners

Plastic fasteners are a common method for securing fender flares. They are often used in conjunction with other fasteners such as screws, bolts, and washers. When installing fender flares, it is important to follow the manufacturer's instructions and ensure compatibility with your vehicle.

If your fender flares come with plastic fasteners, they need to be attached to the flares at the designated locations. These locations are specified by the manufacturer, and you can refer to the manual for guidance. Plastic fasteners are typically pressed or pushed into place, and some may require the use of a #2 Phillips screwdriver for installation.

In some cases, plastic fasteners may be used as replacements for other fasteners. For instance, if your fender flares are held in place with screws, you can remove the screws and use plastic fasteners as an alternative. This can be useful if you are looking for a quicker or more convenient method of installation.

It's worth noting that plastic fasteners can vary in quality and price. While some may be inexpensive and readily available at hardware stores, others can be quite expensive, especially when purchased from dealers.
