What is the plastic behind the front wheel of the Highlander called?
3 Answers
The plastic panel above the front and rear wheels of the Highlander is called the fender. Below are the relevant details: 1. The fender is the outer body panel that covers the wheel, named for its resemblance to a bird's wing in older vehicle designs. 2. Based on installation position, it is divided into front fender and rear fender. 3. The front fender is installed at the front wheel area and must ensure maximum clearance for wheel rotation and movement. Designers use wheel motion diagrams to verify if the fender dimensions are appropriate for the selected tire size. 4. The fender's function is to prevent gravel and mud kicked up by the wheels from splashing onto the underbody during driving. 5. Therefore, the material used must be weather-resistant and have good formability. Some vehicles use flexible plastic materials for front fenders. Plastic materials provide cushioning and are safer.
I've been driving a Highlander for several years and regularly check the car's condition. That plastic thing behind the front wheels, we usually call it the fender liner, also known as the wheel arch liner or splash guard. It's not redundant; its main function is to block stones, mud, and dust thrown up by the tires, protecting the engine area or chassis from getting dirty or corroded. For example, when driving in the rain, mud and water are intercepted by it, preventing damage to wiring or mechanical parts. Usually, pay attention to cleaning its backside to prevent accumulated dirt from causing water retention and rust. I drive a lot in the north, where winter road salt tends to stick to it, so it needs to be rinsed off promptly. If you notice any cracks or looseness, get it fixed immediately—replacing one is low-cost, just a few hundred bucks. Remember, this small part may seem simple, but it can extend your car's lifespan and driving safety.
As someone who frequently works with cars, I've repaired numerous Highlanders. That plastic component behind the front wheel is professionally called a wheel arch liner, commonly known as the inner fender. It acts as a barrier, preventing mud, water, and debris splashed by the tires from damaging the engine compartment and suspension system. I've seen many owners neglect it, leading to mud seepage that causes short circuits and overheating issues. Made of ABS plastic, it's durable but prone to cracking upon hard impact. During installation, the clips must align properly to avoid rattling noises. Maintenance-wise, I recommend checking it every six months, especially after rainy seasons or off-road driving. Replacement isn't difficult, but always opt for genuine parts to ensure proper fit and maintain flatness to prevent water pooling. Paying attention to these details makes for a quieter and more worry-free ride.
