TrakMotive AD-8091 front left CV axle shaft for the 2004-2009 Audi S4 and other vehicles sends drive torque to the front left wheel. It keeps power flowing as the suspension moves and the wheel steers.
A clicking or popping noise on turns, grease thrown from a torn boot, or vibration while driving can mean this CV axle shaft is worn, though a worn wheel bearing or an out-of-balance tire can be behind some of the same signs. This listing is one CV axle shaft for the front left, which takes one; the front right is a separate part, ordered separately.
This CV axle shaft fits the 2004-2009 Audi S4, the 2002-2008 Audi A4 and the 2007-2008 Audi RS4.
