Tighten up your Audi's front suspension geometry with the Mevotech Supreme control arm and ball joint assembly (CMS70189). It installs as a direct-fit replacement in the front right upper rearward position on the 2011-2018 Audi A8 quattro and 2013-2018 Audi S8 — see the Buyer's Guide tab for engine-specific coverage.
The control arm locates the wheel and hub through the suspension's travel, while the integrated ball joint provides the pivoting connection to the steering knuckle. When the original arm or its ball joint wears, you may notice clunking over bumps, steering wander, or uneven tire wear — if a worn arm or joint is the cause, this assembly replaces it.
As a Mevotech Supreme suspension control arm, it's built for high-usage passenger vehicles, SUVs, fleets and working trucks.
