Common issues with the Toyota Hiace D-4D often revolve around wear and tear of suspension components due to its use as a commercial vehicle.

It's important to be aware of diesel fuel contamination issues that might affect injectors and fuel pumps.
During a Warrant of Fitness inspection, your Hiace D-4D will be scrutinised for: Suspension components (bushes, ball joints, shocks), Steering system play, Brake hose condition, Brake performance including wheel cylinders, Glow plug function (especially in colder months) which can affect emissions. A worn universal joint represents an immediate failure.
Maintaining your Hiace D-4D is all about understanding its key components and addressing them promptly. Common parts that often require attention include the universal joints and couplings, which are essential for efficient power transfer. Inspect these for wear regularly to avoid any unexpected troubles on the road. The steering rack is another crucial area; keep an eye out for leaks or play that might compromise your handling. As autumn approaches, don't forget about the glow plugs, essential for smooth starts in colder weather—replace them to prevent issues during those brisk mornings.
For those accustomed to commercial use, the suspension components, especially the suspension bushes (front control arm - lower, rear control arm - upper), require regular checks to maintain optimal handling. It's recommended to review these parts during service intervals to catch any deterioration early on. Remember to examine your rear shocks for comfort and stability, and ensure the front brake hoses are free of cracks and wear.
The cooling system stands out as a critical area—usually requiring inspection around the 150,000km mark. Parts like the water pump, thermostat, and radiator hoses should all be thoroughly checked to prevent overheating and maintain engine performance.
