Locate the front wheel and let it travel and pivot for steering with the Mevotech Supreme control arm and ball joint assembly (CMS70145). This front left lower rearward unit installs as a direct-fit replacement for the listed applications: the 2008-2009 Audi A5 Quattro, 2008-2009 Audi S5, 2009-2010 Audi A4, 2009-2010 Audi A4 Quattro, 2009 Audi Q5, and 2010 Audi S4.
As a Mevotech Supreme suspension control arm, this Audi A4 control arm carries the lower ball joint that ties the knuckle to the chassis, positioning the wheel while allowing suspension travel and steering movement. If your Audi S4 control arm or its ball joint is worn, clunking over bumps, loose or wandering steering, or uneven front tire wear can be signs it may need replacing — and if a failed arm is the cause, this assembly replaces it.
