7/12/2023 0 Comments Differential fluidIt accomplishes this goal by distributing torque across both left and right turning forces, allowing them to act on the ground separately.Ī differential also provides a mechanical advantage by taking advantage of the gear ratio.įor example, a single-speed axle will have higher leverage on one side than on the other, thus providing more torque on one side instead of another. A differential’s primary function is to reduce the effort needed to turn the wheels so the vehicle can move. This Is What Happens If You NEVER CHANGE YOUR DIFFERENTIAL OIL!ĭifferentials are an essential part of every vehicle equipped with axles, basically any car with wheels. Must Read Transfer Case Leaking Oil Explained and Fixed. This is by far the scariest problem with front differential fluid. Unfortunately, these friction modifiers and anti-oxidants may not be enough to protect the metal in the gears and bearings from corrosion after a while.Īs you drive your vehicle, metal particles are constantly being ground up by the gears, which have high contact pressures in areas where metal-to-metal contact occurs. Most vehicles use gear lube containing some friction modifiers and anti-oxidants. In several cases, people were told their front differential was fine and then found out it had failed after taking it off-roading. Unfortunately, this is a fairly common failure. Over time, this corrosion can make the fluid unsuitable for use. Due to the performance of your vehicle’s engine, temperatures can rise in the differential fluid, eventually causing corrosion. Your front differential fluid needs changing every 40-60k miles for best performance and long life.Ĭorrosion is a gradual deterioration that accelerates when the fluid gets hot and cools down. Unfortunately, it’s also one of the most expensive parts of your car, so it’s essential to take good care of it. How Often Should I Change Front Differential Fluid?Īs you know, the front differential is the part of your vehicle that divides up power so it can be applied to both wheels. Is It Necessary To Change Your Car’s Differential Fluid?.Benefits Of Changing Differential Fluid.Whining Noise From Transmission Or Differential.How Often Should I Change Front Differential Fluid?.Also, everyone can’t change the fluid by themselves at home.īecause they do not have the proper gears or the tools for it, that is why it is suggested to take care of your car to a good mechanic shop instead of wasting your time and effort on it. Thus it is better to take your car to a professional or the mechanic shop to get the fluid changed. Moreover, sometimes it can be messy and dirty while changing the fluid, which would increase your workload. The whole process of replacing the differential fluid is a little bit challenging. You have to lift the car with the help of a jack and then have to remove the drain plug to change the differential fluid. This is because it is not a single person’s task. It is recommended that you never change the differential fluid by yourself.
