(Your vehicle may have more than one differential in it depending on the drivetrain.) As you can imagine, it's important that the lubricant in those differentials do its job. Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often. Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km ... read more
