Bring firm, precise steering and a settled ride back to your 2014-2020 Chevrolet Impala with the Mevotech Supreme control arm and ball joint assembly (CMS501250). This front left lower unit is a direct-fit replacement for the listed Impala applications, pairing the lower control arm with a pre-installed ball joint so you replace both worn parts in one step.
Engineered in-house with application-specific upgrades and Labor Saver designs, this Mevotech Supreme suspension control arm is built for high-usage passenger vehicles, SUVs, fleets and working trucks. A worn control arm bushing or a failing ball joint can bring on clunking over bumps, uneven tire wear, and loose or wandering steering; if a worn front lower control arm or ball joint is the cause, this assembly replaces it.
