Splash guard
The plastic piece inside the wheel well above the axle is called a splash guard, or an inner fender liner. It is also known as a wheel arch liner in the UK. This plastic piece acts as a protective shield, preventing water, mud, and debris from entering the engine area and causing corrosion or wear on the axle and suspension components. Splash guards can crack or detach over time, leading to debris buildup and potential axle damage. Regular inspections for cracks or loose fasteners are recommended, and broken clips or the entire guard may need to be replaced to maintain proper protection and prevent costly repairs.
In some cases, the entire inner fender is referred to as the fender liner, with the corner pieces called fender spats. The generic term for this component is "wheel well guard" or "wheel-well shroud." It is important to note that this part is different from the fender, which is at the front of the car. The correct terminology is crucial to avoid confusion when ordering replacement parts.
The process of replacing a splash guard involves sourcing a new one from a dealer or a junk yard. It is recommended to inspect the vehicle regularly for any damage to the splash guard and to replace broken clips or the entire guard if necessary. This proactive approach ensures the vehicle's components are protected and helps avoid more expensive repairs in the future.
Overall, the plastic piece by the wheel, known as the splash guard or inner fender liner, plays a vital role in safeguarding the engine and other critical components from the elements and debris. Regular maintenance and replacement of this part are essential to maintain the vehicle's performance and longevity.

Wheel arch liner
The plastic part by the wheel is called a wheel arch liner, or a wheel arch cover. It is an arch-shaped cavity in the body of a vehicle that houses the wheel. Its primary function is to protect the car from mud when driving. It also serves the purpose of ensuring the safety of pedestrians and other vehicles in the event of a collision, as it prevents the wheel from flying into the air.
Wheel arches are susceptible to corrosion and damage from road metal impact. Therefore, it is important to regularly inspect them for rust or noticeable damage. If any damage is detected, repair work may be needed. This can include reinforcing the structure or eliminating damage through welding or gluing. To extend the life of wheel arches, substances can be applied to protect against corrosion and damage from gravel and other solid objects.
In some cases, it may be necessary to install wheel arches with a larger diameter, which requires mounting special wheel arch cover extensions. If the wheel arches experience significant damage, new components must be installed. Severe metal corrosion is another indicator of the need for replacement.

By preventing the ingress of salt, mud, and other contaminants, they help to maintain the vehicle's performance and extend the lifespan of critical components. Additionally, these shrouds improve the aesthetics of the vehicle by filling in unsightly gaps and voids, resulting in a sleek and finished appearance.
It is important to regularly inspect wheel well shrouds for any damage, as cracks or loose fasteners can compromise their protective capabilities. Proper maintenance involves replacing broken clips or the entire guard to maintain optimal protection and prevent costly repairs. Overall, wheel well shrouds play a crucial role in safeguarding the vehicle's underbody and performance, ensuring a more durable and reliable driving experience.
