What is the difference between Full-Time 4WD and Part-Time 4WD systems?
What is the difference between Full-Time 4WD and Part-Time 4WD systems?
Full-Time 4WD systems utilize a center differential, which enables the front and rear driveshafts to turn at different speeds, thereby allowing engagement on dry surfaces for normal driving conditions. A Part-Time system does not employ a center differential and locks the front and rear driveshafts together. With a Part-Time system, 2WD mode should be used during normal driving conditions and 4WD mode is to be used only when off-road or on wet or slippery surfaces.
