CARDONE New 66-7261 front right CV axle for the 1998-2004 Audi A6 Quattro and other vehicles carries drive torque from the transmission to the wheel. Its two flexing joints let the wheel steer and move with the suspension.
- Neoprene boots with extra bellows where needed to resist bellow stress and cracking, the leading cause of boot failure
- CV axle shafts individually verified for straightness, for vibration-free performance at all speeds
- Measurements validated after assembly to confirm proper fit
- Boot clamps pneumatically crimped to seal the boot to the housing
- Grease that withstands high temperature and high torque demands
- Precision-rolled splines and threads for fit in the hub, the transmission and the axle nut

What can clicking when I turn hard and accelerate mean for a front CV axle?
