A vehicle transfer case is where power in an all-wheel-drive or a four-wheel-drive vehicle is moved to the back wheels. Most vehicles have front-wheel drive, you need a device to send some energy to the back wheels to give it a drive. This is where the transfer cases are used to connect the propeller shaft to both the engine and the wheels. It also helps to switch between four-wheel drive and a two-wheel drive from time to time. Due to this it usually comes under a lot of pressure, hence it is vital to have a good understanding of the working principle of the case and maintain it in a good shape.
Working of a Transfer Case
If you ever think of opening up a transfer case, you will find three shafts, gears, and a differential. One of the three-shafts will be an input shaft, which is connected to the engine. The shaft is responsible to take the transmission and transfer it to the two separated output shafts. The output shafts are connected to the front-wheel-drive and the second wheel drive system. This means that the case is a vital component that drives the vehicle.
The system also contains a differential system that helps to maintain different speeds. One of the output shafts will spin at a higher rate than the other one. This is done so that you can avoid the driveline bind when driving on a hard surface.
Common Problems Associated With the Transfer Case
The most well-known issues are crushing or grinding that occurs in the gears. You can identify it when you hear sounds coming from the vehicle when you switch gears. Sometimes you may see smoke from the vehicle that may come from a broken case. Additionally, in case if the alignment is not done properly, then you may hear some sounds while driving.
There are some cases where the case may be broken and liquid spills out. It is important to repair the case as soon as possible in this case, as any debris can further damage the case. If you run a faulty case in your car, then it may lead to much more problems in the future.
Can You Replace The Case?
Yes, it is highly advised to replace a broken or a faulty transfer case. Before you do anything on your own, it is vital to consult with a mechanic. They will help you to identify the perfect case for your car. You can either purchase an original factory case or go to the aftermarket for some good cases for your vehicle.
The transfer case is one of the most important parts of a vehicle. It is important to take good care of the case so that your car can have a healthy life. Make sure you opt for a regular check-up of the car after every milestone is completed. This makes sure that all the parts of the vehicle are checked regularly.
