Truck Service Cost Calculator
Estimate the cost of servicing a light rigid, heavy rigid or prime mover in Australia, by service level and the wear items that come due with it.
Most fleets run an A, B, C cycle where each level includes everything below it plus extra tasks.
Keep every service record, invoice and defect rectification note for the life of the vehicle. Under the Heavy Vehicle National Law, maintenance is a chain of responsibility obligation, and in an incident investigation the absence of records is treated as an absence of maintenance regardless of what was actually done to the truck.
💰 Ways to save
- Compare a dealer service against a heavy vehicle independent on labour rate and parts source separately, because the gap is usually in labour. Dealer rates commonly run $180 to $260 an hour against $130 to $190 at an established independent, and on a C service running eight to fourteen hours that is a difference of several hundred dollars. Quality independents use the same filters and oils, so ask which brand and specification rather than assuming genuine parts are the differentiator.
- Move to a scheduled maintenance program with fixed intervals rather than servicing on breakdown or when it feels due. Unplanned downtime is the real cost in a truck operation, since a day off the road on a linehaul unit is commonly $800 to $1,500 in lost revenue plus the recovery, which dwarfs the price difference between a planned and an unplanned repair. Fleets that move to condition monitoring with oil sampling typically catch driveline problems a service cycle before they become failures.
- Bundle the wear items into a scheduled service rather than booking them separately. Brake relines, air dryer cartridges, wheel alignments and the annual inspection all require the truck on a hoist and much of the same disassembly, so doing them inside a planned service window saves both labour and a second day of downtime. Ask your workshop to forecast which wear items will fall due at the next two services so you can plan the spend rather than react to it.
- Use oil sampling on any unit past about 400,000 kilometres. A sample costs roughly $30 to $60 and reads wear metals, coolant contamination, fuel dilution and soot loading, which tells you about bearing wear, a weeping head gasket or an injector problem well before it becomes a rebuild. On a fleet, a sampling program routinely pays for itself several times over on a single avoided engine failure.

Understanding truck service costs in Australia
What truck servicing costs in Australia in 2026
A routine A service, essentially oil, filters, lubrication and a safety inspection, runs about $450 to $800 on a light rigid, $700 to $1,100 on a medium or heavy rigid and $900 to $1,500 on a prime mover. A B service, which adds driveline, fuel system and brake attention, is roughly $900 to $1,600 on a rigid and $1,400 to $2,600 on a prime mover. A C service, the major interval where valve lash, coolant, differential oils and a deeper inspection come in, lands at $2,000 to $4,000 on a rigid and $3,000 to $6,500 on a prime mover before any parts that get found along the way. Oil volume alone explains a lot of the spread, since a prime mover engine takes 35 to 45 litres against 12 to 18 on a light rigid, and quality heavy duty diesel oil is $6 to $10 a litre.
The A, B, C service cycle and what each level covers
Most Australian fleets and dealers run a tiered cycle where each level includes everything below it. The A service is the frequent interval, typically every 20,000 to 40,000 kilometres or 250 to 500 hours depending on the make and the duty, and covers engine oil and filter, fuel filters, a greasing round, fluid levels, a brake and tyre check and a general safety inspection. The B service comes at roughly double the A interval and adds air dryer service, transmission and driveline attention, closer brake inspection with measurement, and fuel system checks. The C service is the major, usually annually or every 100,000 to 200,000 kilometres, and adds valve lash adjustment, coolant replacement and testing, differential and gearbox oil changes, injector inspection and a comprehensive chassis assessment. Reading a quote without knowing which level it covers is meaningless.
What actually drives the price
Vehicle class is the obvious driver, through oil volume, filter count, the number of grease points and the physical labour of working on a large vehicle. Duty cycle is the underappreciated one. A truck doing urban stop start, heavy PTO work such as a tipper or a concrete agitator, or long idle periods accumulates engine hours far faster than the odometer suggests, and servicing to distance rather than hours is a recurring cause of premature turbo, injector and DPF trouble. Emissions equipment adds real cost on any Euro 5 or Euro 6 unit, since the DPF, AdBlue dosing system and EGR all need periodic attention and the AdBlue system in particular is sensitive to contamination and crystallisation. Age matters too, because a truck past half a million kilometres will find something at every C service.
Compliance, records and the Heavy Vehicle National Law
Truck maintenance in Australia is not just an economic decision, it is a legal obligation, and the record keeping is as important as the work. Under the Heavy Vehicle National Law, which applies in every state and territory except Western Australia and the Northern Territory which run their own equivalent schemes, maintenance sits within the chain of responsibility framework. That means an operator must ensure the vehicle is safe and must be able to demonstrate it, and in an incident investigation or an audit the absence of maintenance records is treated as the absence of maintenance. Keep every invoice, every defect notice and every rectification record for the life of the vehicle. Operators accredited under the National Heavy Vehicle Accreditation Scheme maintenance module have a documented system for this and gain some inspection concessions in return, which is often worth the administrative overhead for a fleet of any size.
Inspections, roadworthies and brake testing
Annual or periodic heavy vehicle inspection requirements vary by state, with New South Wales requiring an annual inspection for heavy vehicles, Queensland operating a certificate of inspection regime, and other jurisdictions with their own arrangements, so check what applies where the vehicle is registered rather than assuming. Budget $250 to $500 for the inspection itself, and understand it is an inspection, not a service, so anything it finds is quoted separately. Roller brake testing is increasingly used both at inspection and as a fleet diagnostic, and it is genuinely useful because it measures actual braking effort per axle and exposes imbalance that a visual check misses. That imbalance is why relining a single axle is generally false economy, and why most operators do axles in pairs.
Dealer versus independent, and regional availability
Dealer labour rates commonly run $180 to $260 an hour against $130 to $190 at an established heavy vehicle independent, and on a C service running eight to fourteen hours the difference is meaningful. Dealers hold the deepest parts stock, the manufacturer diagnostic software and the factory technical bulletins, which matters most on late model emissions equipped units and anything under warranty. Independents are usually better value on routine work and on older trucks, and quality operators use the same filters and oil specifications. Regionally, availability rather than price is the constraint. Major freight corridors and mining and agricultural centres are well served, while a breakdown in a thinly serviced area means waiting on parts freight, so many regional operators carry critical spares themselves and build a relationship with a workshop rather than shopping every job.
Planning the spend rather than reacting to it
The single biggest cost lever in truck maintenance is not the hourly rate, it is downtime. A linehaul unit off the road is commonly $800 to $1,500 a day in lost revenue before any recovery cost, which dwarfs the difference between a planned repair and an unplanned one. Operators who run a fixed interval schedule, forecast wear items two services ahead and use oil sampling on higher kilometre units consistently spend less in total than those servicing on failure, even though their invoice line looks higher. Ask your workshop to project the next two services including likely wear items so brake relines, tyres and inspections can be bundled into a planned window. Oil sampling at $30 to $60 a shot is the cheapest early warning available and routinely pays for itself on a single avoided engine failure.
Frequently asked questions
How much does a truck service cost in Australia?
An A service is about $450 to $800 on a light rigid, $700 to $1,100 on a rigid and $900 to $1,500 on a prime mover. A B service runs $900 to $1,600 on a rigid and $1,400 to $2,600 on a prime mover. A C service, the major interval, is $2,000 to $4,000 on a rigid and $3,000 to $6,500 on a prime mover before any parts found during the work.
What is the difference between an A, B and C truck service?
Each level includes everything below it. An A service is the frequent interval covering oil, filters, greasing, fluid levels and a safety inspection. A B service adds air dryer service, driveline and transmission attention, measured brake inspection and fuel system checks. A C service is the major, adding valve lash adjustment, coolant replacement, differential and gearbox oils, injector inspection and a full chassis assessment.
How often should a truck be serviced?
An A service typically falls every 20,000 to 40,000 kilometres or 250 to 500 hours depending on the make and duty, B services at roughly double that, and a C service annually or every 100,000 to 200,000 kilometres. Service to hours rather than distance on any unit doing urban stop start, heavy PTO work or long idle periods, because those accumulate engine hours far faster than the odometer suggests.
Do I have to keep truck maintenance records?
Yes. Under the Heavy Vehicle National Law maintenance sits inside the chain of responsibility framework, so an operator must ensure the vehicle is safe and be able to demonstrate it. In an incident investigation or an audit, missing records are treated as missing maintenance regardless of what was actually done. Keep every invoice, defect notice and rectification record for the life of the vehicle.
Is a dealer or an independent better for truck servicing?
Dealers charge $180 to $260 an hour against $130 to $190 at an established heavy vehicle independent, and hold the deepest parts stock, the manufacturer diagnostic software and factory technical bulletins. That matters most on late model emissions equipped units and anything under warranty. Independents are usually better value on routine work and older trucks, and quality operators use the same filter and oil specifications.
How much does a brake reline cost on a truck?
Roughly $700 to $1,200 per axle depending on the class of vehicle and whether drums or discs, plus the labour to do it. Most operators reline axles in pairs rather than singly, because relining one axle creates a braking imbalance that shows up on a roller brake test. Bundle it into a scheduled service window, since much of the disassembly overlaps and you save a second day of downtime.
