  • What are the most common truck repairs needed?

    Common truck repairs include brake system overhauls, clutch replacements, suspension repairs, electrical diagnostics and cooling system fixes. Heavy vehicles experience wear and tear faster due to load and mileage, making preventative checks important. Early signs of trouble, like uneven tyre wear, strange engine noises or delayed braking, should never be ignored. Staying ahead with scheduled servicing can help avoid emergency repairs and reduce downtime on the road.

  • How often should a heavy truck be serviced?

    The ideal service interval depends on truck type, usage, and manufacturer guidelines. On average, trucks should be serviced every 10,000 to 20,000 km, or every 3–6 months for heavily used vehicles. Some trucks may require more frequent inspections, particularly if they’re used for long hauls, towing, or construction work. Regular servicing ensures safety, fuel efficiency and helps detect problems before they become major issues.


  • What’s included in a full truck service?

    A full truck service generally includes an oil and filter change, inspection of brakes, suspension, cooling systems and tyres, and checking lights, fluid levels, and belts. Some workshops, like RTA-authorised stations, can also carry out roadworthiness inspections. Depending on mileage, more in-depth checks, like valve adjustments or fuel system cleaning, may also be included. Servicing is essential for maintaining compliance and avoiding expensive breakdowns.
