How Does Four-Wheel Drive Work? Four-wheel drive is similar to all-wheel drive in that it sends torque to the four wheels of a vehicle to increase traction as needed, Instamotor explains. HoweverFull-Time 4WD (Full Time 4WD) This is a four-wheel-drive system that can be operated continuously on all surfaces. It powers all 4 wheels at all times. A full-time 4WD system may include the option of part-time operation (allowing you to shift into 2WD on dry pavement, for example) and may or may not have Hi and Lo speed ranges.
Transfer case is the part connected after the transmission box of 4 wheel drive/ All wheel drive vehicle, which transfers the power from the transmission to the front wheels and rear wheels. In other words, the transfer case connects the front propeller shaft and the rear propeller shaft to the transmission output shaft.
4LOW, you can shift into 4LOW on the QTII and QDII systems. Check your Owner's Manual, I'm pretty sure that locks the center differential will require wheels to slip on loose surfaces in turns. i.e. do NOT engage 4LOW on-road and make turns, it will bind up and can damage the drivetrain.
An all-wheel drive (AWD) vehicle is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand. As the name implies, all-wheel-drive systems power both the front and rear wheels all the time. But in practice, there are actually two types of drivetrains that are called AWD.
