Pinpoint Test B: Driveline Clunk Or Ting - Occurs As The Vehicle Starts To Move Forward Following A Stop

  1. 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 right CV joint is locked in the intermediate shaft by a snap-ring. The left CV joint is locked in the differential by a snap-ring.
