Locate the rear wheel and keep it tracking through its intended arc with the Mevotech Supreme Lateral Arm and Ball Joint Assembly, MPN CMS861056. This rear upper rearward unit drops in as a direct-fit replacement for the 2011-2012 Lexus IS F, 2006-2015 Lexus IS250, 2006-2015 Lexus IS350, 2006 Lexus GS300, 2007-2011 Lexus GS350, 2006-2007 Lexus GS430, 2007-2011 Lexus GS450H, and 2008-2011 Lexus GS460 — see the Buyer's Guide tab for engine-level details.
- A faster fit: ships with a part-specific nylon locking nut to speed ball joint installation.
- Forged steel construction: built to OE-level tolerances for the load the arm carries.
- Resists corrosion: a protective surface treatment helps guard against rust build-up.
- Rigorous testing: extensive in-house and third-party durability testing backs its performance.
The lateral arm links the wheel knuckle to the chassis and, together with its integrated ball joint, controls wheel movement and helps hold suspension geometry. Premium materials are used on all components. If worn arm bushings or a loose ball joint are the cause, common signs include clunking or knocking over bumps, uneven tire wear, and loose or wandering steering — diagnose the cause before replacing. Install as directed by the vehicle service procedure and have the alignment checked afterward.
