Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS30121
Firm up a loose front end with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly CMS40171 — a direct-fit F-150 control arm that installs in the front right lower position on the 2009-2013 Ford F-150, 2007-2013 Ford Expedition and 2007-2013 Lincoln Navigator. This control arm and ball joint assembly locates the front wheel and lets the suspension pivot through its travel, while the integrated ball joint carries the steering and ride motion. If a worn arm or ball joint is behind clunking over bumps, steering wander or uneven front-tire wear, replacing it addresses that cause.
Engineered in-house as part of the Mevotech Supreme line, this Mevotech Supreme control arm drops in for the listed applications. See the Buyer's Guide tab for engine-level fitment.
