This set basically handles how power gets distributed to the front and rear wheels, especially in four – wheel drive. It's a collection of gears, chains, and sometimes a viscous coupling or clutch pack. It manages the split – how much power goes where – and lets you switch between two – wheel drive, four – wheel high, and four – wheel low. It also allows for different speeds between the front and rear axles when you're in four – wheel drive, which is critical for off – roading or slippery conditions. Think of it as the central distributor for power when you engage four – wheel drive. The engine sends power to the transmission, and then the transfer case takes that power and directs it to both the front and rear driveshafts. It’s a really crucial part of the drivetrain, sitting right between the transmission and the axles. It’s what makes your vehicle four – wheel drive capable. Well, if this set fails, you lose your four – wheel drive capability, plain and simple. You might notice grinding noises when you try to engage four – wheel drive, or it might not engage at all. Sometimes it’ll engage intermittently. If a chain breaks inside, you’re definitely going to notice. The transfer case itself acts like a shield protecting those internal parts, but the set inside is what’s doing the work. If you regularly use four – wheel drive – or if you’ve started to notice issues with it – getting this sorted out is important. Fixparts Online has a good range of these, and we can check if this Secure Set fits your specific vehicle if you give me your make and model. It's one of those things you don’t really think about until it goes wrong, but it's vital for a lot of vehicles, especially trucks and SUVs.
