4x4 Systems

For vehicles used primarily on-road, every 50,000-80,000 km is typical. For off-road use or towing, we recommend every 30,000-40,000 km. If you frequently cross water or drive in dusty conditions, more frequent changes protect against contamination. We'll check fluid condition during any service and advise if it needs changing.

Warning signs include grinding or clunking when engaging 4WD, vibration in certain drive modes, difficulty shifting between 2WD and 4WD, fluid leaks from differentials or transfer case, whining noises from the drivetrain, and the 4WD indicator light flashing. Don't ignore these - 4WD problems can worsen quickly.

Absolutely. We specialize in building capable off-road vehicles. Popular upgrades include differential lockers (ARB, electric, or auto), upgraded axle shafts, heavy-duty CV joints, and transfer case gearing changes. We'll discuss your intended use and recommend upgrades that make sense for your driving style.

In 4WD vehicles, clicking when turning usually indicates worn CV joints, especially common in vehicles with independent front suspension (IFS). The CV boots may have torn, allowing grease out and dirt in. Caught early, sometimes just the boot or joint can be replaced. Left too long, the entire axle may need replacement.

Yes, we service all types of 4WD and AWD systems including part-time 4WD (like Land Cruisers and Patrols), full-time AWD (like some Land Rovers), and selectable systems. Each type has different service requirements and we're experienced with all of them.
