Tighten up loose, wandering steering and quiet a knocking front end with the Mevotech Supreme control arm, part number CMS70109. This Mevotech Supreme suspension control arm is a direct-fit replacement for the front left upper forward position on the 2006-2011 Audi A6, 2005-2011 Audi A6 Quattro, 2003-2010 Audi A8 Quattro, 2007-2011 Audi S6, 2003 and 2007-2009 Audi S8, and 2004-2006 Volkswagen Phaeton. It locates the wheel knuckle and allows the suspension and steering to move through their travel; the integrated ball joint is included, so the arm and joint are replaced together as one unit.
If a worn control arm or ball joint is the cause of clunking over bumps, imprecise steering, or uneven front tire wear, this Audi A6 suspension arm replaces the failed part. Diagnose the cause before ordering.
