Can you turn 4wd off while driving?

In general, it is not recommended to turn 4WD off while driving, especially at high speeds. While some newer vehicles may have electronic systems that allow for switching between 2WD and 4WD on the fly, it's important to refer to the owner's manual for specific instructions and precautions. Some older vehicles and vehicles without advanced electronic systems may require coming to a stop before disengaging 4WD, as driving in 4WD on dry pavement can put stress on the vehicle's drivetrain and potentially cause damage. Always consult the owner's manual or consult with a qualified mechanic to determine the safe operation and limitations of your specific vehicle before attempting to switch between 2WD and 4WD while driving.
