Ford Differential Service
In most Ford vehicles, it takes several stops before engine power makes it to the tires and to the ground so you can move. Power is developed in the engine and sent through the transmission. In front-wheel drive and rear-wheel drive vehicles, power is distributed by differential gears to the axles, wheels, and tires. In all-wheel drive and four-wheel drive vehicles, the transfer case or PTU distributes power to front and rear differentials.
What is Ford Differential Service?
Some Ford front differential gears are simply part of the transmission, so they don't get a separate service, but all rear differentials, and some front differentials need periodic service. Differential gears are bathed in heavy oil to prevent wear and promote smooth power transfer. When you ask for a Ford differential service, one of our factory-trained technicians will drain the differential and refill it with fresh oil. Some vehicles might require additives, such as for limited-slip differentials.
Why should I get a Ford Differential Service?
Differential oil doesn't heat up as much as engine oil or transmission fluid, but it's still a factor in how long it lasts. Your Service Advisor at Bickley Ford will tell you when you should have the service done, but it depends much on how and where you drive. Driving habits, towing and hauling heavy loads can increase wear, and off-roading can introduce water into the oil, reducing protection, as well as any submersion in water from loading and unloading boats into the water.
What happens if I don't get Ford Differential Service?
Over time, most oils and oil additives tend to break down. If you put off a Ford differential service for too long, this might lead to excess wear in the differential gears or bearings. Just like a missed Brake Replacement Service, clunking and whining noises could result. In extreme cases, limited-slip differentials might fail, and even the heavy gears of the differential could break under stress. Because the differentials are hidden, it can be difficult to tell how worn the oil has become, so it's a good idea to change it before any wear becomes obvious.
