How long does it take to change differential fluid

Differential fluid, even on cars that stress their differentials, doesn't need nearly as regular a change as something like engine oil.

Based on mileage alone, engine oil should be inspected or changed every 7,500 to 10,000 miles, depending on your car manufacturer's specifications. However, the recommended checkpoint to change differential fluid varies depending on the manufacturer and your car's drivetrain.

Ford's 2009 Scheduled Maintenance Guide (PDF), for instance, recommends that you change the differential fluid at 150,000 miles for 4x4s.

The mileage checkpoint varies depending on just how much stress you put on your vehicle.

For example, Toyota mechanics would tell you that 30,000 miles is enough time to start looking at your differential fluid. The first 30,000 miles is an important checkpoint because that has given the new differential gears enough time to "break in," and there's likely to be a lot of metal shavings from it.
