Top 5 Common HGV Mechanical Issues and How to Prevent Them

 

Regular maintenance from HGV Mechanic North West is the key

Keeping your HGV in top condition is essential for ensuring both safety and efficiency on the road. However, heavy vehicles face unique challenges due to their size, weight, and constant use. In this post, we'll explore the top 5 common mechanical issues in HGVs and how to prevent them.

 

1. Brake System Failures

One of the most crucial components in any vehicle, especially HGVs, is the braking system. Over time, brakes can wear down or develop faults due to the heavy loads these vehicles carry. Common problems include air brake leaks, worn brake pads, and overheated rotors.

Prevention: Regularly inspect brake pads, discs, and callipers. Ensure the air brake system is checked frequently for leaks or pressure drops. Early detection of wear and tear can help avoid costly repairs or dangerous failures.

2. Tyre Wear and Blowouts

HGV tyres are subjected to significant stress due to the weight they carry. Uneven wear, underinflation, or overloading can lead to dangerous tyre blowouts, which not only put the driver at risk but can also cause delays in deliveries.

Prevention: Always check tyre pressure and condition before every trip. Rotate tyres regularly and ensure they're balanced to reduce uneven wear. Avoid overloading the vehicle to extend tyre lifespan.

3. Suspension System Issues

The suspension system in HGVs ensures a smooth ride and helps maintain vehicle stability. Worn-out suspension components, such as shock absorbers or springs, can lead to poor handling and increased tyre wear.

Prevention: Regularly inspect the suspension system for signs of wear, including unusual noises or excessive bouncing. Replacing worn-out components before they fail will improve ride quality and vehicle safety.

4. Transmission Problems

Transmission failure is another common issue in HGVs due to the heavy loads and constant shifting between gears. Over time, gear slippage, grinding noises, or delayed shifting can occur.

Prevention: Routine servicing of the transmission system, including checking and replacing fluids, can help prolong its life. Addressing any unusual noises or gear changes immediately can prevent more severe damage.

5. Electrical Faults

HGVs rely on complex electrical systems to operate everything from lights and indicators to engine management. Electrical faults can cause a range of issues, from minor annoyances like flickering lights to serious problems like engine malfunctions.

Prevention: Regularly check the battery, alternator, and wiring for any signs of corrosion or damage. Ensuring that all electrical components are functioning properly can help avoid unexpected breakdowns.
