Shopping for a DELPHI control arm to replace a worn rear suspension link? The Delphi Suspension Control Arm and Ball Joint Assembly TC7388 is cataloged for the rear right position and installs as a direct-fit replacement for the listed 2009-2012 Infiniti FX35, 2009-2013 Infiniti FX50, 2013 Infiniti FX37, and 2014-2017 Infiniti QX70. It locates the wheel and, through its integrated ball joint, lets the suspension travel while helping keep alignment and tire contact consistent.
By combining both wear items in one control arm and ball joint assembly, it replaces the arm and joint together. Signs the original may need replacing include clunking or knocking from the rear suspension over bumps, loose or wandering steering, and uneven tire wear; diagnose the cause before replacing.
