Normal Operation and Fault Conditions
Halfshafts transmit rotary motion through constant velocity joints in a uniform manner. The outer CV joints use balls, have no length compensation and engage in the wheel hubs. The intermediate shaft (right side) is correctly positioned and secured in the differential by the intermediate shaft center bearing. The left CV joint is locked in the differential by a snap-ring.
