Truck Maintenance 101: Extending the Life of Your Volvo, UD or Mack Truck

October 15, 2026

For any transport business, a truck is more than just a vehicle – it’s an essential part of keeping your operation moving. Whether you’re hauling freight across the country, navigating regional roads or tackling demanding work every day, keeping your Volvo, UD or Mack truck in top condition is key to maximising uptime, managing operating costs and protecting your investment.

The good news? A proactive approach to truck maintenance can make a significant difference to your vehicle’s long-term performance and reliability.

At Western Truck Group (WTG), we understand the importance of keeping your truck on the road and earning its keep. From manufacturer-approved servicing and genuine parts to service agreements designed around your business, there are plenty of ways to help extend the working life of your truck.

Here are our essential truck maintenance tips to help you get the most out of your Volvo, UD or Mack truck.

1. Stick to Your Scheduled Servicing

One of the simplest and most effective ways to extend the life of your truck is to follow its recommended service schedule.

Regular servicing helps identify wear and potential issues before they develop into more significant problems. It also helps keep critical systems operating as intended, supporting reliability, roadworthiness and long-term performance.

Routine maintenance may include:

• Engine oil and filter changes.

• Brake inspections and servicing.

• Tyre inspections and pressure checks.

• Fluid level checks and top-ups.

• Engine, transmission and electrical system diagnostics.

• Air conditioning and other essential equipment maintenance.

Every truck has different requirements, so always follow the manufacturer’s recommended servicing intervals for your specific model and application. Trucks operating under heavy loads, in extreme temperatures, in dusty environments or on frequent stop-start routes may require more frequent attention.

WTG offers professional truck servicing through its authorised dealership network, with skilled technicians, factory-standard workshop facilities and modern diagnostic technology to help keep your vehicle performing at its best.

2. Don’t Ignore the Early Warning Signs

Small issues can quickly become expensive repairs if left unchecked. Unusual noises, warning lights, changes in braking performance, fluid leaks or unexpected changes in fuel consumption can all indicate that something needs attention.

Taking action early can help prevent further component damage, reduce the risk of an unexpected breakdown and minimise disruption to your business.

Make vehicle inspections part of your regular routine. Before setting off, take a moment to check for visible leaks, inspect your tyres, confirm that lights are working and look for anything unusual. Drivers should also report changes in vehicle performance promptly so that potential problems can be investigated.

For anything beyond routine checks, consult a qualified technician rather than allowing a minor concern to develop into a major repair.

3. Use Genuine Parts to Protect Your Investment

When it comes to maintaining a Volvo, UD or Mack truck, the quality of replacement parts matters.

Choosing genuine manufacturer parts helps ensure the components are designed for the vehicle, supporting compatibility, durability and dependable performance. Using the correct parts can also help protect critical systems and reduce the risk of issues associated with unsuitable replacements.

WTG stocks genuine Volvo, UD and Mack truck parts, along with a range of all-makes parts and accessories for other makes and models. Our experienced parts team can help you identify the right components for your vehicle and application.

And there’s another benefit to consider: WTG offers a 24-month warranty on both the part and labour when eligible genuine manufacturer truck parts are fitted by our expert technicians, subject to the applicable warranty terms.

Whether you’re replacing filters, brake components, electrical parts or other essential items, choosing the right parts is an important step in keeping your truck working reliably for longer.

4. Keep Your Tyres, Brakes and Safety Systems in Check

Tyres and brakes play a vital role in the safety, efficiency and performance of your truck. Regular inspections help identify wear, damage or developing faults before they compromise your vehicle or your schedule.

Tyre pressure, tread condition, uneven wear and visible damage should all be monitored. Incorrect tyre pressure and poor alignment can contribute to premature tyre wear, while worn braking components can affect stopping performance and vehicle safety.

Your maintenance routine should also include checks of lighting, electrical systems and other essential safety equipment.

WTG’s service team can assist with brake inspections, mechanical repairs, maintenance and the fitting of truck accessories. If a component needs replacing, its parts specialists can help source the appropriate parts for your truck.

Remember, regular checks are not just about avoiding breakdowns – they’re about helping protect your drivers, your cargo and everyone sharing the road.

5. Take a Preventative Approach to Maintenance

When a truck is working hard, it can be tempting to put off maintenance until something goes wrong. However, reactive repairs can lead to unplanned downtime, missed delivery commitments and unexpected expenses.

Preventative maintenance takes a different approach. Rather than waiting for a problem to appear, it focuses on identifying potential issues and addressing them before they escalate.

A good preventative maintenance plan should include:

• Following manufacturer service intervals: Use your truck’s recommended maintenance schedule as the foundation of your plan.

• Keeping accurate service records: Track completed work, upcoming maintenance and recurring issues.

• Monitoring vehicle performance: Pay attention to warning alerts, changing operating conditions and developing faults.

• Planning repairs ahead of time: Schedule workshop visits to minimise disruption to your transport operations.

• Reviewing maintenance requirements: Adjust your approach to suit the truck’s workload, age and operating environment.

For fleet operators, a consistent preventative maintenance program can make it easier to manage vehicle availability, control repair expenditure and plan servicing across multiple trucks.

6. Consider a Service Agreement for Greater Cost Certainty

Maintaining a truck involves more than the occasional workshop visit. For businesses operating one truck or managing an entire fleet, knowing when servicing is due – and what it is likely to cost – can make budgeting much easier.

That’s where a manufacturer service agreement can help.

WTG offers both Volvo, UD and Mack service agreements designed to help operators plan maintenance and manage their ongoing operating costs.

A service agreement won’t eliminate every unexpected repair, but it can help make routine maintenance more predictable and support a more proactive approach to vehicle care.

Contact your local WTG team to discuss which options suit your truck and business.

7. Give Older Trucks the Attention They Deserve

A truck doesn’t necessarily need to be replaced simply because it has accumulated kilometres or spent years on the road. With the right maintenance, repairs and component replacements, an older truck may continue to deliver valuable service.

As trucks age, however, it’s important to pay closer attention to component wear and the condition of critical systems. Regular inspections can help identify which components need attention and where preventative repairs may help avoid more significant problems.

Our Midlife Packages are designed to help protect your investment by combining genuine parts with expert installation to refresh key systems. These packages aim to help operators:

• Maximise vehicle uptime.

• Reduce the risk and cost of unexpected breakdowns.

• Restore performance by refreshing key systems.

• Extend the life of critical components.

• Help maintain the truck’s future value.

WTG also offers genuine parts at everyday low prices for selected older Volvo, UD and Mack models, helping owners maintain trucks that may no longer be in production.

For operators looking to keep an established truck in service, discussing the vehicle’s condition and maintenance requirements with an experienced technician can help determine the most practical next steps.

8. Make the Most of WTG’s Service Network

For trucks covering long distances, travelling through regional areas or working across multiple locations, access to reliable servicing and parts support is an important consideration.

Western Truck Group operates dealerships across Queensland, the Northern Territory and regional New South Wales, including Toowoomba, Darwin, Cairns, Townsville, Mackay, Rockhampton, the Sunshine Coast and Dubbo. WTG is also supported by a network of regional Customer Service Centres.

As part of the broader Volvo Group Australia dealer network, WTG provides authorised sales, parts and servicing support for Volvo, UD and Mack trucks.

This network gives operators access to knowledgeable parts teams, skilled technicians and servicing support across a broad geographic area. For businesses managing multiple trucks, having access to a consistent network can also help simplify maintenance planning and support fleet operations.

Whether you need routine maintenance, mechanical repairs, genuine parts or advice on managing an ageing vehicle, working with a team familiar with your truck’s brand can make maintaining your investment easier.

9. Remember That Maintenance Is an Investment, Not Just an Expense

It’s easy to focus on the immediate cost of a service or replacement component. However, the bigger picture includes the potential cost of a breakdown, lost operating time, missed deliveries and premature component failure.

A well-maintained truck can be more reliable and fuel-efficient, while a structured maintenance plan can help operators manage total ownership costs over the vehicle’s working life.

The key is to be consistent. Follow the manufacturer’s servicing recommendations, monitor the truck’s condition, use appropriate replacement parts and seek professional advice when something doesn’t seem right.

Every truck and application is different, so the best maintenance strategy is one tailored to your vehicle, workload and operating conditions.
