Differential Fluid Service | Huntington Beach
How does differential oil work in my vehicle?
As you cruise down the road, the gear oil splashes about lubricating gears, bearings and clutch packs. The differential oil lubricates the ring and pinion gears that transfer power from the driveshaft to the wheel axles. If your car is fitted with a limited-slip differential, it also keeps all the moving parts in that assembly healthy. The purpose of the differential fluid is to cool and lubricate your differential. Without the oil your differential would overheat due to the metal-to-metal contact and burn itself out.
How often do I need to change the differential oil?
Unless the gear oil has been contaminated with water, you should change the differential oil at the time recommended by the owner’s manual of your vehicle. If you don’t have the owner’s manual, we have access at Great Canadian Oil Change to all manufacturers’ recommended service intervals.
Why is it important that I have it changed when recommended?
Changing this oil is just as important as changing your engine’s oil, and for the same reason. Metal-to-metal contact wears down surfaces and creates heat from friction, which inevitably weakens the gears and leads to failure. To keep your differential in optimum condition and to avoid costly repairs, it is best to follow the manufacturer’s recommendation on when to change the differential oil.
