Trucks are the workhorses of the road, hauling heavy loads and travelling vast distances. Regular maintenance is crucial to keeping them running smoothly, and replacing worn-out parts at the right time is essential to avoid costly breakdowns and ensure the truck operates efficiently. In this blog, we’ll look at the most common truck parts that need replacement and how to spot when they’re wearing out.
1. Tyres
Truck tyres endure constant stress due to heavy loads and long journeys. Over time, they wear down and need replacing to ensure the truck remains safe on the road.
Tyre Wear and Tear
Tyres gradually lose their tread, reducing grip and traction, which can lead to dangerous driving conditions, especially in wet weather. The weight of cargo also adds pressure, causing tyres to wear out faster than in smaller vehicles.
When to Replace Tyres
There are a few tell-tale signs that your truck tyres are due for replacement:
- Tread depth is below the legal limit (1.6mm in most regions).
- Visible damage to the tyre sidewalls, such as cracks or bulges.
- Uneven wear patterns, which could indicate alignment or suspension issues.
2. Brakes
Brakes are a vital safety component that must be in top condition to handle the demands of truck driving. Over time, the brake pads and discs will naturally wear out due to friction.
Brake Pads and Discs
Brake pads press against the discs to stop the vehicle, and with constant use, these pads become thinner, reducing their effectiveness. Discs can also become worn or warped, affecting braking performance.
Signs of Brake Wear
There are several indicators that the brakes need attention:
- Squealing or grinding noises when braking.
- Vibration through the brake pedal.
- Reduced braking power or the truck pulling to one side when braking.
3. Batteries
Truck batteries work hard, especially in extreme weather conditions. Cold temperatures can drain battery life, while constant engine starts and stops put extra strain on the battery.
Battery Life
The average truck battery lasts around three to five years, but frequent use and tough weather conditions can shorten this lifespan.
When to Replace
Watch out for these signs that your truck’s battery is failing:
- Slow engine start or needing multiple attempts to start the engine.
- Dim lights or electrical components not working properly.
- Visible corrosion around the battery terminals.
4. Suspension Components
A truck’s suspension system supports the heavy loads it carries, making it essential for both performance and comfort. Over time, key components like shocks and struts wear down and need replacing.
Shocks and Struts
Shocks and struts absorb the bumps and roughness of the road, ensuring a smooth ride and helping maintain proper contact between the tyres and the road surface.
Signs of Worn Suspension
- Uneven tyre wear, often indicating that the suspension isn’t holding the truck level.
- Excessive bouncing after hitting a bump or pothole.
- Difficulty steering or feeling less control when turning.
5. Filters
Filters play an important role in keeping the engine clean and running efficiently. Over time, they become clogged and need replacing to prevent engine damage and performance issues.
Air Filters
Air filters trap dust, dirt, and other debris before they reach the engine. A clogged air filter restricts airflow, which can reduce engine efficiency and fuel economy.
Fuel Filters
Fuel filters keep the fuel clean as it enters the engine. If they become blocked, the engine may struggle to get enough clean fuel, leading to poor performance.
Replacement Indicators
Signs that your air or fuel filters may need replacing include:
- Reduced engine power or sluggish acceleration.
- Poor fuel efficiency.
- Frequent stalling or difficulty starting the engine.
6. Belts and Hoses
Belts and hoses may seem like minor parts, but they play a vital role in keeping various systems in the truck functioning properly. Over time, they wear out and can crack or leak.
Drive Belts
Drive belts power multiple components in the truck, including the alternator, air conditioning, and power steering. A worn belt can snap and cause significant issues.
Hoses
Hoses carry fluids like coolant and hydraulic fluid through the truck’s systems. With time, they can become brittle and develop cracks or leaks.
Signs of Wear
Look out for the following signs that belts or hoses need replacing:
- Cracks or fraying in the belts.
- Fluid leaks under the truck.
- Engine overheating, which could indicate a coolant hose issue.
7. Lights and Electrical Components
Properly functioning lights are crucial for safety, and like other truck parts, they need replacing from time to time to ensure your truck is visible on the road.
Headlights and Taillights
Truck lights naturally dim or burn out over time, reducing visibility and increasing the risk of accidents, particularly in low-light or adverse weather conditions.
Electrical Issues
Wiring and fuses can also fail, causing lights or other electrical components like indicators and dashboard lights to malfunction.
Conclusion
Keeping your truck in top shape requires regular inspections and timely replacement of key parts. Tyres, brakes, batteries, suspension components, filters, belts, hoses, and lights all need attention to ensure your truck remains safe and efficient on the road. Regular maintenance not only prevents costly breakdowns but also extends the life of your truck and improves its performance.
By staying on top of these common replacements, you can minimise downtime and keep your truck running smoothly for many years to come.
