Four-wheel drive oil operates in a tough environment. The multi-plate clutch wears the oil over time and so it needs replacing to maintain efficiency. Clean oil ensures the components in the four-wheel drive system are always in peak operational condition.
Four-wheel drive oil works very hard to maintain the lubrication of the multi-plate clutch. If this oil is left unchanged it becomes dirty and worn out, which means it can't lubricate the clutch correctly eventually leading to system failure.
We remove the oil from the system and replace it with fresh oil of the correct grade to the correct level.
