A transfer case is the part of a four-wheel-drive system that transfers power from the engine to the axles while driving around Mystic, CT. If you've ever driven a car with four-wheel drive, you're familiar with what happens when you engage it. As soon as you put your foot on the gas, one wheel turns faster than the other.
This is because there are two differentials between them. One for each axle, and they allow each wheel to turn at its speed.
But getting power from one differential to another isn't as simple as just connecting them with a long chain or cable. It wouldn't work because they'd be spinning at different speeds. Instead, there needs to be some sort of mechanism that can transfer power from one differential to another smoothly and reliably over time. That's where a transfer case comes in.
A transfer case has gears inside it that allow it to engage with both differentials at once. Power can be transferred from one side of the vehicle to another without making any noise or causing extra strain on components like belts or hoses.
