Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC1666
Steer with confidence and quiet the front suspension with the Delphi Control Arm with Ball Joint TC5025, a front left upper control arm and ball joint assembly. This Ford Fusion control arm installs as a direct-fit replacement for the 2009-2012 Ford Fusion, 2009-2012 Lincoln MKZ, and 2009-2011 Mercury Milan — see the Buyer's Guide tab for engine specifics.
The Delphi control arm positions the wheel and pivots as the suspension travels, while the integrated ball joint lets the steering knuckle swivel through its arc. If a worn control arm or ball joint is behind clunking over bumps, loose or wandering steering, or uneven front tire wear, this assembly replaces the failed part.
