Known issues

Rust is a major enemy, particularly in coastal areas of NZ. Check cab corners, rocker panels, and the chassis. Steering boxes often develop play, and ball joints and suspension components wear due to the trucks age and usage. Engine oil leaks from gaskets and seals are common. Carburetor issues can plague older models, impacting fuel economy and drivability. Wiring harnesses can become brittle and prone to shorts.

WOF tips

Check for excessive rust, especially around structural points like the chassis and suspension mounts. Steering play is a common WOF failure point, as are worn suspension components. Ensure all lights are functioning correctly, and that the brakes are in good working order, including the parking brake. Pay close attention to exhaust system leaks, as these can lead to a WOF failure.
