See Figure 1
The front drive axle uses a conventional ring and pinion gear set to transmit the driving force of the engine to the front wheels. The halfshafts are completely flexible, consisting of an inner and outer constant velocity (CV) joint connected by an axle shaft. The inner CV joint is a TRI-POT design, which can move in and out. The outer CV joint is an RZEPPA design which is also flexible, but can not move in and out.
