Keep your front suspension tight and predictable with the Mevotech Supreme control arm and ball joint assembly (CMK80524), a direct-fit replacement for the 2002-2010 Audi A4, 2002-2010 Audi A4 Quattro, 2004-2009 Audi S4 and 2007-2008 Audi RS4. It installs in the front lower forward position, locating the wheel and carrying the integrated ball joint that lets the knuckle pivot as you steer and travel over the road.
Worn control arm bushings or a failing ball joint can show up as clunking over bumps, wandering or loose steering, and uneven front tire wear. If a failed lower arm or ball joint is the cause, this Mevotech Supreme suspension control arm replaces the whole assembly in one step. Sold individually; order two for a complete left-and-right replacement.

Where does this Audi A4 control arm mount?
It installs in the front lower forward position, locating the wheel and pivoting on its integrated ball joint as the suspension moves and steers.
Is the ball joint included with this control arm?
Yes. This is a one-piece assembly with the ball joint built in, so you replace the arm and ball joint together rather than pressing in a separate joint.
What are the signs this Audi S4 control arm may need replacing?
Clunking over bumps, wandering or loose steering, and uneven front tire wear can indicate a worn arm bushing or ball joint. Diagnose the cause before replacing.
Does it come with mounting hardware?
It includes the part-specific nylon locking nut to speed installation. Consult the vehicle service information for the correct fasteners and whether any may be reused.
