Four-wheel drive vehicles, sometimes called 4×4 or all-wheel drive, demand rugged performance, especially when used for off-roading and towing.
And components that have to work extra hard require periodic TLC. Take the transfer case, for example. It helps deliver power from the transmission to the wheels. In four-wheel drive, power from the engine is directed to both the front and rear axles. In all-wheel drive, it shifts power from one axle to the other, depending on conditions. Your transfer case requires lubrication, just like the engine and transmission. It has its own fluid, which should be checked and changed at regular intervals. This is even more important in four-wheel and all-wheel drive vehicles because if the fluid degrades enough, the vehicle might not be able to shift into four-wheel drive.
Similarly, the differential requires regular maintenance. This gear box is located between the drive wheels and allows them to turn at different speeds as the vehicle is taking turns. Over time, the properties of the lubricating fluid inside deteriorate, resulting in improper lubrication of the gears. At Auto Select, we’ll replace the old fluid with fresh fluid, which helps avoid excessive wear on the differential. This is key to saving yourself a costly differential or axle replacement.
