Understanding the Common Issues with the A-Pillar Molding
The A-pillar is the structural component of your vehicle that supports the windshield and connects the roof to the body. On the Ford Explorer, the exterior trim piece covering this pillar is notorious for becoming loose or even flying off at high speeds. This happens because the plastic clips and adhesive backing used during manufacturing can degrade due to heat, UV exposure, and wind pressure.
When the trim begins to lift, it creates a gap that catches the wind, leading to a high-pitched whistling or humming noise. If ignored, the wind force can eventually snap the remaining clips, causing the entire plastic piece to detach from the vehicle. This is not just a cosmetic issue; it can be a significant hazard to other drivers behind you on the road.
Ford has issued Technical Service Bulletins (TSBs) and even recalls regarding this specific part because of the safety risks involved. Understanding that this is a known design flaw helps you realize that a simple “push” back into place is rarely a permanent fix. You need a systematic approach to ensure the trim stays bonded to the chassis regardless of the weather or your driving speed.
How to Replace Your 2018 ford explorer a pillar trim Correctly
Replacing the 2018 ford explorer a pillar trim requires patience and the right set of tools to avoid damaging the painted surfaces of your vehicle. Before you begin, ensure you have a clean workspace and that the vehicle is parked out of direct sunlight, as heat can make the plastic more prone to warping during removal. Follow these steps to ensure a secure installation.
Step 1: Removing the Old Trim and Clips
Start by using a plastic trim removal tool to gently pry the old molding away from the A-pillar. Avoid using metal screwdrivers, as these will easily scratch your paint or crack the windshield glass. Work from the top of the pillar downward, releasing the clips one by one as you go.
Once the main trim piece is removed, you will likely see several plastic clips still stuck in the metal pillar. These must be removed carefully; sometimes a pair of needle-nose pliers is the best tool for squeezing the tabs and pulling them out. Be sure to clear away any old adhesive or foam tape residue left behind on the vehicle body.
Step 2: Surface Preparation
Surface preparation is the most critical part of the entire process for long-term success. Use isopropyl alcohol and a microfiber cloth to thoroughly clean the recessed channel where the new trim will sit. Any wax, dirt, or old adhesive will prevent the new clips and tape from bonding correctly.
If you notice any rust or paint chips in the channel, this is the time to address them with a small amount of touch-up paint. Ensuring the metal is smooth and clean provides the best foundation for the new molding. Allow the alcohol to evaporate completely before moving on to the next step.
Step 3: Installing the New Molding
Take your new trim piece and align the clips with the corresponding holes in the A-pillar. It is often helpful to start from the bottom near the cowl and work your way up toward the roofline. Apply firm, even pressure over each clip location until you hear a distinct click, signifying that it is locked in place.
Many professional mechanics also recommend using a small bead of urethane adhesive or high-quality automotive weatherstrip adhesive on the underside of the trim. This provides a secondary layer of security beyond the plastic clips. Once the trim is pressed down, use automotive-grade masking tape to hold it firmly in place for at least 24 hours while the adhesive cures.
Essential Tools and Materials for the Job
To perform a professional-grade repair on your 2018 ford explorer a pillar trim, you should gather your supplies beforehand. Having the right tools prevents the “mid-project scramble” and ensures you don’t accidentally break new parts during the installation process. Here is what we recommend keeping in your DIY kit.
- Plastic Trim Removal Set: These non-marring tools are essential for prying without damaging paint.
- Isopropyl Alcohol (70% or higher): Used for de-greasing the mounting surface.
- Microfiber Towels: For cleaning without leaving lint behind.
- Needle-Nose Pliers: For removing broken clips from the pillar holes.
- Automotive Weatherstrip Adhesive: Provides extra “insurance” against the trim flying off.
- Blue Painter’s Tape: Used to hold the trim in place while the adhesive sets.
Using OEM (Original Equipment Manufacturer) parts is highly recommended for this specific repair. While aftermarket versions are available and often cheaper, the fitment of the clips is extremely precise. OEM parts from Ford have gone through several revisions to address the detachment issues found in earlier versions of the 2018 model year.
The Importance of Clip Integrity and Alignment
The 2018 ford explorer a pillar trim relies on a series of specialized clips that are designed to be “one-time use” components. When these clips are pressed into the pillar, their plastic tabs expand to lock the trim against the body. If you attempt to reuse old clips, they will likely have micro-fractures or weakened tabs that will fail under wind load.
Proper alignment is equally important because if the trim is slightly “cocked” or off-center, it creates a lip that the wind can catch. Even a 1-millimeter gap at the leading edge can generate enough lift at 70 mph to start the vibration process that eventually leads to failure. Always double-check that the rubber seal integrated into the trim is sitting flush against the windshield glass.
If you find that the clips are not lining up perfectly, do not force them. Check to see if there is any debris inside the pillar holes or if the trim piece itself is slightly warped. A gentle taping with the palm of your hand is usually enough to seat a properly aligned clip; if you have to hammer it, something is likely misaligned.
Safety Considerations for DIY Mechanics
When working on the 2018 ford explorer a pillar trim, safety should be your primary concern. While this is a relatively simple exterior repair, it involves working near the edges of the windshield glass. Tempered glass is strong, but a sharp impact from a metal tool on the edge can cause the entire windshield to crack or shatter instantly.
Furthermore, be aware of the side curtain airbags that are located just behind the interior A-pillar trim. While you are working on the exterior, you generally won’t interfere with them, but avoid drilling or using long screws in this area. If you find that the metal pillar itself is deformed from a previous accident, it is best to consult a professional body shop rather than attempting to “force” the trim to fit.
Finally, always perform a “tug test” after the adhesive has cured. Gently pull on the edges of the trim to ensure it feels solid. If there is any play or movement, it is better to address it now in your driveway than to have the piece fly off on a busy interstate, potentially causing a multi-car accident behind you.
Differences Between Inner and Outer A-Pillar Trim
It is important to distinguish between the exterior molding and the interior trim. The exterior 2018 ford explorer a pillar trim is the plastic piece that faces the wind and rain. Its primary job is aerodynamics, water shedding, and aesthetics. This is the part most commonly associated with the “flying trim” phenomenon.
The interior A-pillar trim, on the other hand, is the fabric-covered or textured plastic piece inside the cabin. This piece houses the grab handles (if equipped) and covers the airbag modules. If you are experiencing a water leak, it could be the exterior trim’s seal failing, which then allows water to drip down behind the interior trim and onto your floorboards.
If your goal is to reduce wind noise, focus on the exterior piece. If your goal is to fix a rattle inside the cabin or install a dashcam wire, you will be working with the interior piece. Make sure you are ordering the correct part number for your specific needs, as the terminology can sometimes be confusing in parts catalogs.
Frequently Asked Questions About 2018 ford explorer a pillar trim
Is there a recall for the 2018 Ford Explorer A-pillar trim?
Yes, Ford has issued recalls (such as Recall 24V-035) for certain Explorer models because the A-pillar trim can detach while driving. You should check your VIN on the NHTSA website or contact your local dealer to see if your vehicle is covered for a free repair.
Can I use silicone instead of automotive adhesive?
It is not recommended to use standard household silicone. Silicone can trap moisture against the metal and lead to corrosion. It also doesn’t have the same shear strength as urethane or specialized automotive weatherstrip adhesives designed to withstand high-speed wind vibrations.
How long does it take to replace the trim?
For a first-timer, the process usually takes about 45 to 60 minutes per side. This includes the time needed to carefully remove the old clips and thoroughly clean the area. The longest part of the process is waiting for the adhesive to cure before taking the car for a high-speed drive.
What causes the trim to fly off in the first place?
The main causes are broken plastic clips and the degradation of the factory adhesive. Over time, the plastic becomes brittle from UV exposure. Once one clip fails, the wind gets underneath the trim and creates a “prying” effect that snaps the rest of the clips in rapid succession.
Do I need to replace both sides at the same time?
While you don’t have to replace both, it is often a good idea. If the adhesive and clips on the driver’s side have failed, the passenger side is likely in a similar state of degradation. Replacing both ensures symmetry in appearance and gives you peace of mind for both sides of the vehicle.
Final Thoughts on Maintaining Your Explorer
Taking care of your 2018 ford explorer a pillar trim is a small task that pays huge dividends in safety and driving comfort. By addressing loose molding early, you prevent costly damage to your windshield and eliminate the annoying wind noise that can ruin a long commute. Remember that the key to a successful repair lies in the preparation and the use of high-quality clips.
As a DIYer, you have the satisfaction of knowing the job was done right. Always prioritize using the correct plastic tools to protect your paint and give the adhesive plenty of time to bond before hitting the road. If you ever feel unsure about the structural integrity of the pillar or the windshield, don’t hesitate to reach out to a certified technician for an inspection.
Stay proactive with your vehicle maintenance, keep your tools ready, and enjoy the quiet, secure ride that your Ford Explorer was designed to provide. Safe driving!
