Truck Mechanic Gladstone | Heavy Vehicle & Trailer Repairs
Workshop and mobile mechanical support for trucks, heavy commercial vehicles, semi-trailers and transport fleets across Gladstone and Calliope.
When a truck is off the road, the cost extends well beyond the repair bill. Missed deliveries, delayed jobs, lost production and disrupted schedules can quickly affect an entire transport or commercial operation.
Total Mobile Mechanical Services provides truck servicing, heavy vehicle repairs, diesel diagnostics and semi-trailer maintenance for owner-drivers, transport operators, contractors and commercial fleets throughout Gladstone, Calliope and surrounding Central Queensland areas.
Our trade capability covers heavy commercial vehicles, mobile plant, light vehicles, auto electrical and automotive air conditioning. This allows our team to investigate mechanical, diesel, electrical, cooling and driveline faults through one business rather than immediately sending the truck between several repairers.
Complete Truck and Heavy Vehicle Repairs Gladstone
Heavy vehicle faults rarely remain confined to one system. A loss-of-power concern may involve fuel pressure, air supply, turbocharger control, wiring, sensors or internal engine condition. Uneven tyre wear may be connected to steering movement, worn suspension or wheel-alignment settings.
Our truck mechanics inspect the connected systems and explain what testing or repairs are required before additional work proceeds.

Truck Servicing Gladstone & Calliope
Regular truck servicing is one of the most effective ways to identify developing faults before they cause a breakdown, roadside delay or larger repair.
Our truck servicing is based on the vehicle’s kilometres, engine hours, operating conditions, loads, service history and manufacturer maintenance requirements.
Depending on the truck and service interval, maintenance may include:
- Engine oil and filter replacement
- Fuel-filter replacement and fuel-system inspection
- Air-filter and intake-system inspection
- Cooling-system and coolant-condition checks
- Belts, hoses, pulleys and tensioner inspections
- Brake and air-system inspections
- Suspension and steering checks
- Wheel-bearing, hub and seal inspections
- Tyre condition, pressures and wear-pattern checks
- Battery and charging-system testing
- Transmission, differential and driveline fluid checks
- Greasing of applicable service points
- Inspection for fluid, air and coolant leaks
- Warning-light and stored fault-code checks
- Reporting of immediate and upcoming repair requirements
Any additional problems identified during the service are reported before further repairs are carried out.
Businesses operating several vehicles can combine truck servicing with our commercial fleet maintenance services for cars, utes, vans, trucks, trailers and mixed fleets.
Heavy Diesel Truck Diagnostics & Repairs
Replacing diesel components without confirming the cause can waste time and money. Modern heavy diesel engines rely on fuel, air, boost, emissions, cooling, electrical and electronic systems working together.

Heavy diesel problems we investigate include:
- Hard starting and no-start conditions
- Loss of power and engine derating
- Excessive smoke
- Uneven running and misfires
- Fuel-pressure and fuel-supply faults
- Injector-related fault symptoms
- Turbocharger and boost-pressure concerns
- Air-flow and intake-system faults
- Sensor, wiring and communication problems
- Engine warning lights and stored fault codes

Truck and Trailer Brake Repairs
Truck and trailer brakes must operate correctly under load. Air leaks, worn components, brake imbalance and adjustment problems can affect stopping performance, tyre wear and vehicle safety.
Our heavy vehicle brake services can include:
- Air-brake system fault diagnosis
- Hydraulic brake diagnosis and repairs
- Air-line and fitting leak detection
- Brake chamber inspection and replacement

Truck Suspension, Steering & Driveline Repairs
Worn steering, suspension or driveline components can cause poor handling, vibration, unstable braking, uneven tyre wear and driver fatigue.
Our truck mechanics can inspect and repair:
- Leaf springs, bushes, shackles and pins
- Air-suspension components
- Shock absorbers
- Steering joints and linkages
- Tie rods and drag links
- Wheel bearings, hubs and seals
- Suspension mounting components
- Tailshafts and universal joints
- Driveline vibrations
- Differentials and axle concerns
- Clutch and transmission-related faults
- Uneven tyre wear and alignment concerns
By handling steering, suspension, driveline, tyres and alignment-related checks through one business, we can investigate the underlying cause rather than simply replacing worn tyres.
Related services include our suspension and steering repairs and tyre and wheel-alignment services .
Truck Auto Electrical Repairs & Diagnostics
Heavy vehicles rely on electrical and electronic systems for starting, charging, engine control, braking, lighting, climate control and communication between control modules.
Truck auto electrical work can include:
- Battery testing and replacement
- Starter-motor and alternator diagnosis
- Charging-system testing
- Wiring and connector repairs
- Lighting and trailer electrical faults
- Sensor and control-circuit diagnosis
- Warning-light and fault-code investigation
- Auxiliary power and accessory faults
- Intermittent electrical problems
- Vehicle-network and communication concerns
A fault code provides direction, but further testing may be required before the failed component or wiring concern can be confirmed.
