How to Install Mud Flaps on a Truck

how to install mud flaps on a truck

There are many reasons why you may want to install or change mud flaps on your truck. Maybe you want something with more personality, or you’re looking for added durability to tackle the long haul. At Uni-Vue, we offer mud flaps semi trucks that stand up to anything and provide excellent advertising. Here’s our guide on how to install mud flaps on a truck.

Step One: Read Any Model-Specific Instructions
Installing mud guards on your vehicle is a relatively simple DIY project. Most custom mud flaps for semi trucks, pickups and automobiles follow a similar installation process, but specific models may have special considerations, so it’s good to check the included manual to be sure. It may come in handy in figuring out how to install mud flaps on a truck.

Step Two: Clean Your Truck’s Surfaces
It’s always best to start the installation with a clean vehicle exterior. This prevents accumulated dirt or dust from scratching the surface after mud guards are added. Clean the wheel wells, tires and surrounding area thoroughly. Dry any portions with screw holes to prevent rust formation.

Step Three: Give Yourself Room To Work

The idea is to have space to stretch out comfortably and reach all necessary screws or bolts. In the case of front mud flaps, turning your truck’s wheels left or right can provide easier access to screws.

Step Four: Check Flap Size and Positioning
Many mud guards come in different sets for front and rear wheel wells. It’s also important to make sure they face the correct direction. With molded splash guards, you can usually look for a left-hand (LH) or right-hand (RH) marking. The left-hand side refers to the driver’s side of the vehicle.

Step Five: Remove the Previous Mud Guard
Remove the screws affixing mud flaps to the truck’s frame, and set them aside. It’s a good idea to inspect the condition of the screws prior to getting started. If these appear rusted or overly tight, spray them with a commercial rust penetrant or lubricant and allow them to sit for a minute. Afterward, loosen all screws with care.

If your vehicle didn’t come equipped with splash guards, it still may have factory holes with screws tightened in their place. If necessary, remove these screws from the wheel well and save them.

Step Six: Drill Any Required Holes
In many cases, drilling will not be required and you can skip to the next step. No-drill mud flaps utilize pre-existing holes for installation. However, if you want to use a special design or your vehicle doesn’t include stock holes, you can drill them yourself:

  • Using the mud guard as a template, mark any required holes on your truck’s frame
  • Drill holes slowly using the correct bit size
  • Perform a test install of the screws prior to attaching your mud flaps

Step Seven: Attach the Mud Guard Using Screws
Now you’re ready to install your new mud guards, but without tightening the screws completely. You may reuse thescrews and washers from your vehicle or replace them with the ones included in your installation kit.

If you see available holes and want to add extra bolts or screws, you can do so for increased strength. When installing any hex nuts, remember to slip them underneath the mud guard, between it and your wheel well.

Step Eight: Adjust and Tighten
Push the mud guard firmly against your vehicle’s frame, and make sure it fits and is correctly aligned vertically. Now tighten all screws by hand. They should feel snug but not overly tight.

Now you know how to install mud flaps on a truck. By following these simple steps you can swap existing mud guards for the best in the business.

Truck Mud Flaps

Many large trucks are equipped with mud flaps, which offer protection from the road and a wealth of other benefits. If you are considering installing semi truck mud flaps on your vehicles, take a closer look at their advantages and benefits.

Prevent Wear and Tear

Truck mud flaps offer a wide variety of benefits for large trucks and their owners. As time progresses, water, rocks, mud, and other debris can cause wear and tear on the tires of a vehicle, and eventually, cause serious and expensive damage. Mud flaps prevent this type of undercarriage damage from occurring and ensures tires last as long as possible.

Other chemicals, such as salts, are placed on the roadways throughout the year, and they can cause extensive damage to the actual mechanical parts of a truck. These chemicals are largely corrosive and are often used before and after inclement weather.

Low-Cost, Effective Advertising

If you are the owner of a trucking, shipping, or retail company, advertising your business probably consumes a large part of your budget. Luckily, there are effective, low-cost ways to advertise your products or services, and installing custom semi truck mud flaps is one of those ways. You can customize your fleet’s mud flaps with your company’s logo (or the image or words of your choosing), and reach a diverse array of drivers.

Durability

Mud flaps are typically manufactured from one of two materials; sheet metal or rubber. metal flaps, usually composed of stainless steel or aluminum, are often considered more visually appealing, and they often have a decorative flair. On the other hand, heavy rubber flaps generally offer more resistance to the weather, and their flexibility allows them to better propel rocks and asphalt.

Lower Your Maintenance Costs

As mentioned above, mud flaps can offer a wealth of benefits and help you lower your repair and maintenance costs over time. Contact Uni-Vue to learn more about our mud flaps today.
