4WD Switch

The 4WD switch is a device that lets you change from two-wheel to four-wheel drive depending on the road conditions.

4WD switch significance

The 4WD switch is typically found in vehicles with 4WD capability and is fundamental for letting drivers alter to a different mode. When you select the 4WD mode, you are essentially linking both the front and rear driveshafts so that they rotate together as one. Without the switch, the car would not be able to go from 2WD to 4WD. Also, you must be driving at a certain speed or be required to stop to engage in 4WD mode.

Common problems with a defective 4WD switch

A faulty 4WD switch can lead to the 4WD getting stuck permanently which can wear out certain parts.
