What is a consequence of operating a 4WD vehicle for extended periods on paved roads in 4H mode?

Operating a 4WD vehicle for extended periods on paved roads in 4H (four-wheel high) mode typically leads to specific consequences. One prominent issue is the potential for abnormal tire wear. This occurs because the front and rear axles are driven simultaneously, which can lead to a difference in tire speed and ultimately result in uneven wear, especially on hard surfaces where the tires do not have the necessary slip that would occur in off-road conditions.

On the other hand, using 4H mode can make shifting in and out of the transfer case more difficult if the system is not being used as intended. Therefore, operating a 4WD vehicle primarily on paved roads does impose certain stresses on the drivetrain that can contribute to these types of wear and shifting difficulties.

In this case, recognizing the impacts of extended 4WD operation on pavements indicates that both tire wear and transfer case functionality are affected. Thus, the most accurate assessment would include both aspects as potential consequences when using such a mode improperly.
