Drive Wheel / Drive Axle
A drive wheel is a wheel in an automotive vehicle that receives power from the powertrain, and provides the final driving force for a vehicle. A two wheel drive vehicle has two driven wheels, and a four wheel drive has four.A steer wheel is one that turns to change the direction of a vehicle. The drive wheel is the end of the axle shaft; it has lugs protruding from it. The lugs are separate pieces that are mounted in the drive wheel. The drive wheel bolts onto the brake drum and the wheel rim of the car itself. It is usually a disc about six or seven inches in diameter. Occasionally the drive wheel and the axle shaft are all one piece.
