Keep your Audi's front end tight and predictable with the Mevotech Supreme control arm and ball joint assembly, MPN CMS70133. This is the front lower forward control arm, and it drops in as a direct-fit replacement for the 2004-2010 Audi A8 Quattro and the 2007-2010 Audi S8 (see the Buyer's Guide tab for engine-level fitment). The arm locates the front wheel and, through its integrated ball joint, lets the steering and suspension move while holding your alignment settings.
This Mevotech Supreme suspension control arm — the Mevotech Supreme lower control arm for these Audis — replaces a worn or failing original. Signs the original may need replacing include clunking over the front end, loose or wandering steering, and uneven tire wear. If a worn control arm or ball joint is the cause, this assembly renews both in a single part.
What vehicles does the CMS70133 fit?
It's a front lower forward direct-fit replacement for the 2004-2010 Audi A8 Quattro and the 2007-2010 Audi S8. Check the Buyer's Guide tab for engine-level details.
Is this a complete control arm and ball joint assembly?
Yes. The ball joint is integrated into the control arm, so you replace both together in one unit, and a part-specific nylon locking nut is included to ease installation.
What are the signs my control arm or ball joint needs replacing?
Common signs include clunking over the front end, loose or wandering steering, and uneven tire wear. Diagnose the cause before replacing, as these symptoms can have other sources.
Should I replace the opposite side too?
Replacing the matching arm on the other side at the same time is good practice for balanced, even front-suspension performance, though it isn't strictly required.
Does this control arm include installation hardware?
It comes with a part-specific nylon locking nut for the ball joint. Consult the vehicle service information for any other fasteners needed and whether they may be reused.
