A transfer case isn’t a ubiquitous component. Transfer cases are typically only on four-wheel-drive (4WD) and all-wheel-drive (AWD) vehicles. You may own a truck or SUV with either of those systems and want to know what this part does. So read this guide to understanding the purpose of a transfer case.
How a Transfer Case Works
You only find transfer cases, or T-cases, in 4WD and AWD vehicles because their main goal is to distribute power from the transmission between the front and rear axles. They work in tandem with the transmission, driveshafts, axles, and differentials to ensure that power disperses evenly between the wheels.
The power goes through the output shaft to a set of chains or gears that operate the transfer case. Most modern cars will utilize chains since they’re quieter and lighter than gears. Even though gears are more common in older vehicles, some people prefer to have a T-case that uses them since they’re more reliable for heavy amounts of torque. This quality makes them perfect for off-road usage.
The Difference Between High and Low Gear
T-cases also utilize a high and low gear system depending on the situation. Typically, they will be in low gear for normal road speeds. However, they can also help vehicles crawl up rocks or hills while off-roading. Most off-roading will require high gear to utilize the extra traction. Newer cars will change between them automatically, but some will need the driver to control them manually.
What To Do if Yours Stops Working
Whether you love to drive down the unbeaten path or simply use your car to get to and from work every day, your T-case can give out on you after a while. That’s this guide on understanding the purpose of a transfer case goes over what to do if your transfer case stops working.
Fortunately, if it breaks down, that doesn’t mean the whole thing needs a replacement. Instead, you can switch out the parts that malfunctioned on you.
