Four-wheel Drive - Systems By Design Type - Part-time

Part-time

These are vehicles that have no center differential. Since there is no center differential to allow for speed differences between the front and rear wheels when turning, a small amount of tire slippage must occur during turns. When used on slick surfaces, this is not a problem, but when turning on dry pavement, the tires grip, then are forced to slip, then grip again, and so on, until the turn is completed. This causes the vehicle to exhibit a 'hopping' sensation. Using part-time 4WD systems on dry pavement is not recommended, as damage to the drive-line eventually occurs.
