Troubleshooting Vehicle Mudguards: Tips for Maintenance

Your vehicle’s mudguards are more than just an accessory - they’re a vital component for protecting your commercial vehicle, ensuring safety, and enhancing performance. Furthermore, mudguards are a legal requirement for most commercial vehicles according to the Individual Vehicle Approval (IVA).

Neglected or damaged mudguards can lead to a host of issues, from simple aesthetic concerns to costly repairs. This article dives into common problems, practical troubleshooting methods, and maintenance tips to keep your mudguards in top condition.

The Role of Mudguards and Why do They Matter?

Mudguards, also known as splash guards, are a spray suppression system that serve as a protective barrier between your commercial vehicle and road debris. They help to minimise the spray of mud, water, and rocks, preventing damage to your vehicles’s undercarriage, wheels, and nearby vehicles.

Protect Vehicle Surfaces: Prevent road grime and debris from causing scratches, paint chips, or corrosion on the vehicle’s body.

Enhance Safety: Reduce spray and debris, improving visibility for other drivers, especially during wet conditions.

Prolong Vehicle Life: Shield sensitive parts like the brakes and suspension system from exposure to dirt and water.

Common Mudguard Issues

Cracks and Breaks

Plastic mudguards are particularly prone to cracks due to their exposure to road debris, extreme temperatures, and sun radiation. Cracks can spread over time, reducing their effectiveness and aesthetic appeal.

Loose or Misaligned Mudguards

Mudguards can become loose due to vibrations, improper installation, or worn-out fasteners. Moreover, misalignment not only reduces protection but can also cause them to rub against tires, creating noise and wear.

Dirt and Grime Build-Up

Mudguards often collect layers of dirt, mud, and grime, making them less effective and harder to clean. If neglected, the build-up can harden, causing irreversible damage.

Rust and Corrosion

Metal mudguards, while sturdy, are prone to rust if exposed to moisture without proper care. Rust weakens the structure, making restoration sometimes inevitable.

How to Fix Common Issues

Inspect Your Mudguards Regularly

Frequency: Inspect mudguards at least once a month or before long trips.

What to Look For: Check for cracks, alignment issues, rust spots, or missing fasteners. Use a flashlight for detailed inspections.

Tightening Loose Mudguards:

Replace missing screws or bolts with rust-resistant hardware. For misaligned mudguards, consult your vehicle’s manual for alignment instructions.

Cleaning Dirt Build-Up:

Tools: Pressure washer, soft brush, and degreaser.

Steps: Rinse off excess dirt, apply degreaser, scrub gently, and finish with a thorough rinse.

When to Replace your Mudguards

If a mudguard is severely cracked, warped, or rusted beyond repair, it’s time for a replacement. Look for mudguards compatible with your vehicle model for a seamless fit.

Please feel free to view the governments guidelines on what Mudguard your vehicle requires under the Commission Regulation (EU) No 109/2011. Alternatively, you can contact Albert Jagger for guidance on this.
