Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS86142
Locate and position the suspension while keeping a solid steering connection with the Mevotech Supreme control arm and pre-installed ball joint (MPN CMS501096). This front left lower forward unit is a direct-fit replacement for the 2008-2009 Pontiac G8, combining the arm, bushings and a serviceable ball joint into one assembly.
Forged steel construction built to OE-level tolerances gives this Mevotech Supreme suspension control arm the strength for high-usage passenger vehicles, fleets and working trucks. As a G8 control arm wears, worn bushings or a failing ball joint can produce clunking over bumps, uneven front tire wear, or wandering steering; if a worn front left lower forward arm is the cause, this assembly replaces it. It covers that one corner, so inspect the opposite side and replace as directed by the service procedure.
