![]() ![]() Depending on the type of wheel, the transfer case may be selectable (as in a four-wheel-drive vehicle) or not selectable (as in an all-wheel-drive vehicle). To control the transfer case, you need an electronic switch. Depending on the driver, you can convert the transfer case into either four-wheel or two-wheel mode, using the drive. The transfer case can be designed from gear or chain drive, so it can be driven by either of the two materials. Essentially, it harmonizes the front and rear wheels with the rotation between them. As the name suggests, the transfer case is responsible for receiving power from the transmission and transfer it to the (front and rear) wheels, using the drive shafts. What is Transfer Case Fluid?Ī transfer case refers to one of the components of the drive train in an all-wheel or four-wheel vehicle. Transfer cases are also called power take-off units (PTU), and these PTU’s come in different types: the 4WD low, transfer CA’s shift type, housing type, etc. The transfer case is not found in all vehicles it is present only in multi-powered axle vehicles like all-wheel and four-wheel-drive vehicles that use both front and back axles. It divides the power from the transmittance amongst all four wheels in your vehicle. And by the time we are through, you would be well informed enough to make effective decisions.Ī transfer case is a somewhat rectangular box that functions as a component of the drive train (a part of the vehicle that is not the engine but conveys power produced by the engine). This article shall be taking you through some very intricate points that concern the transfer case and its fluid. Some of these containments will work their way into the transfer case over time, diluting the transfer case fluid.If you aren’t familiar with the term transfer case fluid, do not fret. In off road driving it will therefore be exposed to all sorts of containments such as dust and mud on the road surface to being submerged as the vehicle passes through pools of water or fords rivers and streams. This is simply because the transfer case is mounted beneath vehicle with no protection. Off Road driving can also result in more frequent fluid changes being required.If you use your truck or SUV to regularly tow a hitched load, then you should keep an eye on the transfer case fluid and be prepared to change it more regularly. Towing will place extra strain on the transfer case mechanism, simply because the vehicle is working harder to pull an additional load.In addition to sheer mileage there are a couple of other factors that can affect the lifespan of transfer case fluid, and require you to make more frequent changes – they are towing and off road driving. Either way, this really highlights the fact that you should find out the typical mileage range for whatever vehicle you own and drive. Why the big difference? No idea, but probably it has something to do with the transfer case mounted in the Ford being more efficient, and putting less wear and tear on the fluid. If you drive a Ford F150 truck on the other hand, then Ford recommend checking and replacing the fluid every 60,000 miles. In a Toyota RAV4 for example, Toyota recommends checking and replacing the fluid every 15,000 miles. ![]() It also helps to protect the inner workings of the transfer case, again from damage caused by excess heat. Again, this will increase mileage by reducing wasted energy, this time in the form of excess heat. Its secondary function is to the cool the moving parts of the transfer case.This both prolongs the lifespan of the transfer case machinery and also increases your miles per gallon by reducing wasted energy. It does this to ensure a maximum transference of power from the transmission to the rear wheels by minimizing friction between all the moving parts. It primarily job is to lubricate the moving parts found within the transfer case.This is transfer case fluid, and it serves a number of purposes. What is Transfer Case Fluid – Part Deux?īecause the transfer case is full of moving parts, it also needs to be filled with plenty of lubricating fluid. ![]() It is therefore a very important component on any 4 wheel or all wheel drive vehicle because quite frankly, without a transfer case you don’t have a vehicle with power in all four wheels. ![]()
