Which component primarily enables angular flexibility between drive shaft sections?

• A. Universal Joint
• B. Differential
• C. Torque Converter
• D. Axle Shaft

Answer: (A)

Angular flexibility between drive shaft sections is provided by the universal joint. It connects two shafts with cross-shaped bearings inside yokes, allowing one shaft to pivot relative to the other while still transmitting torque. This lets the driveline bend as the suspension moves or wheels steer, preventing binding from changes in angle. The other parts don’t serve this purpose: the differential simply splits torque to the wheels, the torque converter links the engine to the transmission through fluid, and the axle shaft carries power to the wheel but doesn’t accommodate angular changes between shaft segments.
