Car Wheel arch liner

Wheel arch is an arch-shaped cavity in the body of a vehicle, which houses a wheel. It has two important functions. It serves for safety of pedestrians and other cars because the wheel is situated in the body of a vehicle. In Formula 1 cars there is no wheel arch. The danger is that when there is a collision of cars, the wheels fly into the air. The second function is to protect the car from mud when driving. For this purpose protective fender guards were created that are assembled in the wheel arch.

Theoretically wheel arch is liable to corrosion. So a material that is not liable to corrosion is used. Moreover, this material is hard to road metal impact. But still, it may be damaged in the result of an accident. It often happens so that protective fender guards break down. But it is easy to replace them. To do this you need to remove the wheel. If there is a serious damage in the wheel arch, it will be more expensive to repair it. It is possible you will need a wheel alignment. That is why a car owner won’t manage to do this.

In some cars wheel arch size is not big. This may become a problem if there must be tire chains on the wheels. In some cases it is impossible to install the chain. Pay attention to this fact when buying car if you will drive the place where it is necessary to use the tire chain. Also it is possible to set a smaller tire with tire chains. Do you want to buy a boot lid, tie rod, mudguard fender, condenser, lambda sensor, steering servo pump, fuel tank or another spare part for your car? In our online shop you will find all necessary spare parts for your car.

Defects of wheel arches

• component deformation;
• fracture of metal as a result of alternating stress impact;
• emergence of rust;
• mudguards or their fasteners are damaged;
• side members work incorrectly;
• cracks and other defects appeared on the surface as a result of mechanical impact.

Signs of the Wheel arch covers defects

• visual wear of the component;
• knocking can be heard under the bottom during driving;
• wheels squeal and knock at cornering;
• wheels produce abnormal noise during driving.

Causes of the wheel arch defects

• impact of moisture and chemicals during a long period of time;
• incorrect fastening of mudguards or the fasteners are loosened;
• mounted wheel arches are designed for the other car model;
• car accident or hitting by solid particles during driving process;
• incorrect wheel mounting;
• dirt is not cleaned from wheel arches, there is no maintenance.

Diagnostics

You must regularly inspect the condition of wheel arches. For that you should have a visual inspection of them, first taking the wheel off. In case you detect rust or noticeable damages a repair is needed.

For checking the Wheel arch covers inside surface it must be demounted: the component must be disconnected from the side member and the fasteners must be taken off.

Service life of wheel arches has no limitations. Their replacement may be unnecessary for the whole car usage period in case of proper maintenance.

Repair and replacement of wheel arches

Repair works are classified into those meant for construction reinforcement, and those providing damage elimination.

To prolong the wheel arches working life to the maximum, you should apply substances against corrosion and hitting by gravel and other solid objects on the Wheel arch covers surfaces. Lockers and reinforcement plates will serve as extra protectors. They should be welded on in case if wheel arch surface suffered a minor damage.

When installing wheels with bigger diameter than the standard one, you should mount special Wheel arch covers extensions. This allows the wheel to freely rotate without touching the wheel arch surface.

Metal patches will be suitable for fixing minor cracks or through gashes. They can be welded on or glued, with the help of a special compound.

If no defects were detected, however, strong noise is heard during driving, it is recommended to cover wheel arches by soundproof material, which role can be played by bituminous materials. The soundproof material is applied in several layers, thus, such works are better to perform at a service station.

If the wheel arches experienced significant mechanical damages as a result of a car accident, new components must be installed. Severe metal corrosion is another sign of replacement need. It appears when a car is staying outside for a long time.
