A warning light, vibration or loss of power can involve more than one system. We consider how the truck behaves, the conditions that trigger the fault and the work already done before recommending the next repair.
Engine, fuel and turbo faults
Hard starting, extended cranking, smoke, poor acceleration or derating can involve fuel supply, pressure, air intake, boost control or engine condition. We investigate the connected mechanical and electrical causes, including restrictions, hoses, sensors and wiring. Fuel, turbo and emissions concerns can be assessed through our heavy diesel diagnostic capability.
Heavy diesel diagnosis and repairs
Starting, charging and electrical faults
A qualified auto electrician supports no-start, charging, lighting, warning-light, sensor and control faults alongside the mechanical team. We assess relevant 12V and 24V circuits, wiring and connections, including intermittent concerns. Tell us whether the fault changes with temperature, vibration or vehicle load, and bring any warning information you have.
Truck auto-electrical repairs
Clutch, gearbox and driveline
Noise, backlash, poor engagement, vibration or movement under load can involve the clutch, gearbox, mounts, universal joints, tailshaft, centre bearing, differential or axle components. We consider connected movement and the conditions that reproduce the symptom. Major component repair or replacement follows the inspection findings, parts requirements and agreed scope.
Clutch repairs and upgrades
Cooling and overheating
Overheating under load can come from coolant loss, radiator restriction, fan control, water-pump condition, belts, hoses, airflow or an engine-related concern. We investigate the system around the symptom, with a dedicated truck cooling and radiator repair service supported by Natrad network capability. Leaks and temperature changes help guide the testing.

Bearings, hubs and wheel ends
Wheel-end heat, noise, movement or lubricant loss can involve bearings, hubs, seals, adjustment, brakes or mounting components. Inspection considers the surrounding condition and evidence of damage. Where a warning light is connected to a wheel-end sensor or wiring concern, our mechanical and auto-electrical capability helps follow the fault across both systems.
Leaks and defects found during servicing
Oil, fuel, coolant and accessible air leaks can need investigation beyond the visible leak point. We also assess defects found during a service or breakdown inspection, separating the immediate fault from related damage and upcoming maintenance. Once the repair is addressed, planned servicing can help keep developing concerns in view.
