* Increased wear and tear: 4WD systems are designed for off-road use where traction is compromised. On paved roads, the drivetrain components experience unnecessary stress, leading to premature wear on the transfer case, axles, and differentials. This will significantly shorten the lifespan of these components and lead to expensive repairs.
* Reduced fuel economy: Engaging 4WD increases drivetrain resistance, resulting in noticeably lower fuel efficiency.
* Binding and damage: On dry pavement with good traction, the wheels can bind, creating stress and potential damage to the drivetrain components. This is particularly true during turns.
* Steering difficulties: The increased resistance from the 4WD system can make steering harder and less responsive, particularly at lower speeds.
The Jeep Grand Cherokee Limited's 4WD system is designed to be engaged only when needed, such as in snow, mud, or other low-traction conditions. It should be disengaged when driving on normal, dry pavement. The system usually has different settings (like Auto, 4H, 4L) and should be used according to the conditions, with 2WD (or Auto, which defaults to 2WD when conditions permit) being used for normal paved road driving.
