Which technology helps prevent jerky steering wheel motions while turning?

The correct choice, which is CV joints, refers to Constant Velocity joints that play a crucial role in the smooth operation of a vehicle's drive system, particularly when it comes to maintaining consistent torque transfer to the wheels during turning. These joints are specifically designed to allow for a flexible connection between the axle and the wheels while accommodating the up and down movement of the suspension and the changes in angles that occur during steering.

When a car turns, the outside wheels travel a longer distance than the inside wheels. CV joints are engineered to handle these variations in distance and angle, ensuring that both wheels can turn smoothly and without interruption. This technology significantly reduces the potential for jerky or harsh steering motions, allowing for a more comfortable and controlled driving experience.

Other components listed, such as the transmission, clutch, and differential, contribute to a vehicle's overall performance, but they do not directly address the stabilization of steering motions during turns. The transmission mainly manages gear changes, the clutch disengages and engages the engine from the drivetrain, and the differential allows for differences in wheel speed during turns but does not directly address the smoothness of the steering itself. Therefore, CV joints are specifically important for minimizing jerky motions when navigating turns.
