What drive train component connects the transaxle to the drive hubs?

The axle half shaft is the component that connects the transaxle to the drive hubs. In front-wheel drive vehicles, the transaxle is located at the front of the vehicle and combines the functions of the transmission and the differential, simplifying the drivetrain layout. The axle half shaft transmits power from the transaxle directly to the wheels, allowing them to rotate and propel the vehicle forward.

In a typical configuration, there are usually two axle half shafts in a front-wheel-drive vehicle—one for each wheel on the front axle. These half shafts can be designed with constant velocity joints (CV joints) at both ends to accommodate the up-and-down movement of the suspension while maintaining a constant rotational speed, which is crucial for smooth power delivery to the wheels without vibrations.

The drive shaft refers to components found in rear-wheel-drive vehicles, where it transmits power from the transmission to the rear differential. U-joints are used in drive shafts to allow for angle changes during suspension movement, but they do not directly connect the transaxle to the drive hubs. The steering rack is part of the steering system and is not related to drivetrain functionality.
