The problem was that an overwhelming majority of Families from all walks of life had to have an SUV because an SUV meant 4WD. The SUV craze that took the American auto marketplace by storm in the late 1980's and well into the 1990's is likely responsible for this. Over the years, most 4WD auto makers have done away with manual hubs and made a switch to automatic hubs.
These were undesirable because the constant 4WD made them suffer from excess wear and stress on all the drivetrain components from the front axle to the rear axle and everything in between, poor gas mileage, and bad street driving characteristics especially on dry pavement. Until then, the typical 4WD vehicle was "full-time" 4WD. Manual locking hubs were invented by Arthur Warn in 1948. Doing this will allow the front axle drive components to stop spinning, saving unnecessary wear and tear on those parts and helping to improve the fuel economy. When four wheel drive is not in use, the locking hubs are used to disconnect the front wheels from the front axle drive components (differential, half-shafts, and driveshaft).
When driving your 4WD vehicle on a slippery, icy, or muddy road, you may care for little else except that each tire has power and is fighting for every bit of traction. On the outside, they appear simple, but on the inside they perform something extraordinary. They are the small dials found in the middle of the two front wheels. Manual locking hubs are located on the front axle of a 4WD vehicle.
