If your car has “4x4” written on the side, that means it’s a four-wheel drive vehicle. Transmission systems on 4x4 cars distribute power between the front and back wheels. You can choose to drive with two wheels or four.

There isn’t too much difference in the basic transmission structures of two- and four-wheel drive vehicles, except that on a 4x4 system, the power is split using a transfer case, which sends the power to the front and rear wheel sets. Your four-wheel transmission will also be able to handle more of a load than a two-wheel drive car.

Common Repairs On 4x4 Transmissions

• Lubrication – Your mechanic will check the lubrication and transmission fluid levels. Low fluid levels can damage the transmission system.
• Leak Checks – Even tiny fluid leaks can have catastrophic consequences. So, make sure you repair minor damage before you have to replace parts or completely rebuild the system.
• Transfer Case – The transfer case transfers power from the transmission to the front and rear wheels. Depending on your car model, this happens mechanically or electrically. Transfer cases are used in both two and four-wheel vehicles, and they need to be serviced regularly.
• Hub Service – Locking hubs on the front wheels are another part that can break on your 4WD vehicle. Locking hubs power the front wheels and provide the maximum grip and traction that improve fuel consumption.
