A Full-Time 4x4 system operates by default in four-wheel drive and can travel safely and securely on all surfaces. The system uses either a clutch or a center differential to allow the front and rear driveshafts to turn at varying speeds. Whether the road is covered in snow or as dry as dirt, this system can be utilized confidently.
Part-Time 4WD operates by default as a two-wheel drive vehicle. Unlike the full-time system, part-time 4WD doesn’t use a center differential. The system instead locks the front and rear driveshafts, making it better for use exclusively during off-road travel or challenging road conditions. When on dry pavement or under normal driving conditions, the driver should switch to the vehicle’s two-wheel-drive mode. If drivers use Part-Time 4WD excessively, they may experience driveline noise or binding that can lead to overheating or early part failure.
