What is the name of the mudguard in front of the front wheel: we understand the terms and purpose

Protection from dirt and stones: why is it important?

Have you ever wondered what is the name of that plastic or rubber part under the fender of a car that protects the body from splashes and flying stones? Many drivers mistakenly call it a “fender liner”, “mud guard” or even an “apron”. In fact, this part has official name - and it depends on its location and design.

Mud flaps are not just an aesthetic element. They perform critical function: prevent body corrosion, protect the paintwork from chipping, and also protect suspension and brake system parts from premature wear. This protection is especially relevant in Russian conditions, where roads are often covered with reagents, and in spring and autumn they turn into mud baths.

But why is it so important to know the exact name? The fact is that when buying spare parts or contacting a car service wrong term may lead to confusion. For example, the fender liner is a wider part that covers the entire wheel arch, and the mudguard is only part of it. Let's figure out how to correctly name this part and what nuances need to be taken into account when choosing or replacing it.

Official name: mudguard or fender liner?

In automotive terminology mudguard in front of the front wheel most often called:

• 🔧 Front mudguard - a general name for a splash-proof part.
• 🚗 Locker (from the English "mud flap" or "splash guard") - a term used in spare parts catalogs.
• 📋 Splash guard - a rarer name, but found in the documentation.
• ⚠️ fender liner — not entirely correct, since the fender liner covers the entire wheel arch, and the mudguard only covers its lower part.

B auto parts catalogs (for example, Exist.ru, Autodoc or Emex) the part is usually listed as Mudguard front left/right or Splash guard (front). At the same time, unique part numbers can be used for different car brands. For example, for Toyota Corolla this could be a part number 51915-02010, and for Volkswagen Golf — 1K6 807 501 A.

It is important to understand that there are mudguards full-time (installed by the manufacturer) and universal (suitable for several models). Standard ones, as a rule, perfectly follow the shape of the arch and are fastened without modifications, while universal ones may require trimming or additional fastenings.

Design and materials: what to choose?

Mud flaps are made from different materials, and their choice depends on the operating conditions of the vehicle. Let's look at the main options:

Material	Benefits	Disadvantages	Service life
Rubber (EPDM)	Flexibility, frost resistance, low price	Over time it becomes dull and may crack	2–4 years
Plastic (polypropylene, ABS)	Lightweight, durable, does not rot	May break under strong impacts	3–5 years
Polyurethane	High wear resistance, resistant to chemicals	More expensive than rubber and plastic	5–7 years
Aluminum or steel	Maximum stone protection	Heavy, may rust, dear	7+ years (with anti-corrosion treatment)

For most passenger cars, the optimal choice will be plastic or polyurethane mudguards. They are lightweight, durable and do not require special care. Rubber options are cheaper, but are more suitable for temporary protection or budget cars. Metal mud flaps are usually installed on SUVs or cars operated in extreme conditions (for example, UAZ Patriot or Toyota Land Cruiser).

When choosing, also pay attention to fasteners. Standard mud flaps are attached to standard clips or bolts, while universal ones may require additional holes in the body. This is especially important for vehicles with plastic bumperswhere drilling could weaken the structure.

How to distinguish a mudguard from a fender liner: key differences

Many people confuse the mudguard and the fender liner, although this different parts with different purposes. Let's figure out what their fundamental differences are:

• 📍 Location:
  • 🔹 Mudguard - fastened from below bumper or arch, covers only the lower part of the wheel.
  • 🔹 fender liner - installed inside the wheel arch, closing it completely or partially.
• 🛡️ Functions:
  • 🔹 Mudguard protects against splashes, dirt and small stones, flying from under the wheels.
  • 🔹 The fender liner prevents dirt from getting into engine compartment, brakes and suspension.
• 🔧 Construction:
  • 🔹 Mud flaps are usually flat or slightly curved, attached to 2–4 points.
  • 🔹 The fenders have complex shape, following the contour of the arch, and are attached to 6–10 points.

On some vehicles (for example, Renault Duster or Nissan X-Trail) mudguards and fender liners installed simultaneously - this provides maximum protection. However, on budget models (like Lada Granta or Kia Rio) often only mudguards are installed, leaving the arches open.

⚠️ Attention: If your car does not have a fender liner, but only has a mudguard, this does not mean that the protection is insufficient. Many modern cars (for example, Hyundai Solaris or Skoda Rapid) are designed taking into account this configuration.

When to replace the mudguard: signs of wear

Mud flaps are consumables, which wears out over time. Their service life depends on the quality of the material, operating conditions and even driving style. Here are the key signs that it’s time to replace the part:

• 🚨 Cracks or tears - are especially dangerous on rubber mudguards, since through them dirt gets onto the body.
• 🔍 Deformation - if the mudguard is bent due to impact and now touches the wheel or bumper.
• 🛑 Lack of fastenings — lost clips or bolts make the protection ineffective.
• 💦 Traces of corrosion on the body under the mudguard is a signal that the part is not doing its job.
• 🔊 Extraneous sounds (creaks, knocks) when driving - perhaps the mudguard is rubbing against the wheel.

If you notice any of these signs, don't delay replacement. A damaged mudguard not only loses its protective properties, but can also damage other elements car. For example, a torn piece of rubber can get into the brake mechanism or heat up on the exhaust system, which will lead to unpleasant consequences.

The service life of mudguards also depends on climatic conditions. In regions with frequent temperature changes (for example, in Siberia or the Far East), rubber parts wear out faster due to loss of elasticity. Plastic mud flaps last longer in such conditions, but can become brittle in the cold.

How to choose a mudguard: step-by-step instructions

Choosing a mudguard is a task that requires attention to detail. Here is an algorithm that will help you avoid mistakes:

1. Determine the make, model and year of the car.

   This is the main criterion. For example, a splash guard for Volkswagen Polo The 2015 may not fit the 2020 model due to changes in bumper design.

2. Check the installation side.

   There are mud flaps left (LHD) and right (RHD). It is impossible to confuse them - they are mirror symmetrical.

3. Select a material.

   Plastic is suitable for urban use; polyurethane or metal is suitable for off-road use.

4. Check the package.

   The kit must contain all the necessary fasteners (clips, bolts, nuts). If they are not available, you will have to purchase them separately.

5. Compare items.

   Use spare parts catalogs (for example, Elcats or EPC) to ensure compatibility.

If you choose universal mudguard, pay attention to its size. He must:

• 📏 Overlap no less 70% wheel width.
• 🔩 Have mounts compatible with your bumper or arch.
• 🚗 Do not interfere with the operation of the suspension (for example, do not cling to the shock absorber during full compression).

⚠️ Attention: When purchasing mud flaps for cars with lifted suspension (for example, UAZ Hunter or Jeep Wrangler) take into account the increased ground clearance - standard parts may not fit in length.

How to check the compatibility of a mudguard without a catalog?

If you do not have access to an electronic parts catalog, take a photo of the old mudguard (from the back, where the fasteners are visible) to the store. Compare the holes and shape with the new part. You can also attach the mudguard to the wheel - it should cover its lower part without protruding beyond the dimensions of the bumper.

Self-replacement: step-by-step master class

You can replace the front wheel mudguard yourself, without resorting to the help of a car service. For this you will need:

• 🔧 Set of screwdrivers (phillips, flat).
• 🔩 Socket wrenches (usually 10 or 13).
• 🧲 Magnet for finding lost fasteners (optional).
• 🧴 Silicone grease for rubber seals (if you are installing a rubber mudguard).

Procedure:

1. Preparing the car.

   Place the car on a level surface and set the parking brake. Raise the front end with a jack and remove the wheel (this will make it easier to access the mounts).

2. Removing the old mudguard.

   It is usually secured with clips and 1-2 bolts. Carefully unclip the clips with a screwdriver, then unscrew the bolts. If the clips are broken, no big deal, they can be easily purchased separately (part number, for example, 608970000 for many European cars).

3. Cleaning the installation site.

   Remove dirt and rust from mounting points. Treat them if necessary WD-40 or similar means.

4. Installing a new mudguard.

   Attach the part to the mounting location and tighten the bolts. Then snap the clips into place. Make sure the mudguard does not touch the wheel when rotating.

5. Check.

   Install the wheel, lower the car and check for any unusual sounds when driving.

If you install universal mudguardYou may have to trim it to fit the arch shape. To do this, use metal scissors (for plastic) or a sharp knife (for rubber). The edges can be sanded so that they do not cling to the bumper.

Tuning and improvements: how to improve protection

If standard mudguards do not cope with the task (for example, with frequent off-road driving), they can be modify or supplement. Here are some proven solutions:

• 🔧 Installation of additional mud flaps on the rear axle.

  Many cars (especially hatchbacks) do not have rear mud flaps from the factory. Their installation will protect the trunk and rear bumper from dirt.

• 🛡️ Reinforced mudguards made of polyurethane or metal.

  Suitable for SUVs and cars operated in difficult conditions. For example, for Toyota Hilux or Mitsubishi Pajero They produce mudguards with anti-gravel coating.

• 🎨 Painting plastic mudguards.

  If the stock mudguards are faded or scratched, they can be painted to match the body color. To do this, use plastic primer and acrylic paint.

• 🔄 Protective films for bumpers.

  In addition to the mudguards, you can stick a transparent anti-gravel film on the lower part of the bumper (for example, 3M Scotchgard).

For offroad lovers there are mudguards with integrated LED lights. They not only protect against dirt, but also improve lighting in the dark. For example, for Jeep Wrangler or Land Rover Defender brands offer such solutions Rigid Industries or Baja Designs.

If you are planning increase ground clearance (for example, by installing spacers under the springs), keep in mind that the standard mudguards may become too short. In this case, you will have to select parts from models with high ground clearance or have them made to order.

FAQ: Frequently asked questions about mudguards

Is it possible to drive without mudguards?

Technically yes, but this will lead to:

• 🔹 Rapid wear of the paintwork on the thresholds and bumper.
• 🔹 Dirt getting into brake mechanisms and suspension.
• 🔹 Risk of chips on the windshield from flying stones (if there are no mudguards on the front wheels).

In some countries (eg Germany) driving without mudguards prohibited and is punishable by a fine.

Which mudguard is better: rubber or plastic?

The choice depends on the operating conditions:

• 🔹 Rubber - cheaper, dampens vibrations better, but wears out faster.
• 🔹 Plastic - more durable, does not harden in the cold, but can break under strong impacts.

For the city, plastic is optimal; for off-road use, polyurethane or metal.

Is it possible to install mudguards from another car model?

Theoretically, yes, but only if:

• 🔹 Match fastenings (distance between holes).
• 🔹 Suitable form (the mudguard should not protrude beyond the dimensions of the bumper).
• 🔹 The material can withstand loads (for example, if you put a mudguard from a car on an SUV, it can quickly break).

It is better to select the part according to VIN code or article number in the catalogue.

What to do if the mudguard begins to rub against the wheel?

Causes and solutions:

• 🔹 Incorrect installation — check the fastenings, perhaps the clips are not latched.
• 🔹 Mudguard deformation - try straightening it with a hairdryer (for plastic) or replace it.
• 🔹 Changed ground clearance — if the car is sagging or, conversely, raised, choose a mudguard of a different length.

Do mudguards need to be painted to match the body color?

This is a matter of aesthetics, not functionality. Painted mudguards:

• 🔹 They look neater (especially on premium cars).
• 🔹 Less noticeable if damaged.

However, unpainted black mudguards are more practical - scratches and dirt are less visible on them. If you decide to paint, use flexible paints for plastic (for example, MOTIP Dupli-Color).
