Keep the rear wheels tracking true with the Mevotech Supreme Lateral Arm CMS501104, a direct-fit replacement for the 2008-2009 Pontiac G8 (see the "Vehicles it fits" section for engine-level details). This rear-suspension lateral arm locates the wheel and controls its side-to-side movement, helping maintain proper rear alignment geometry and stable, predictable handling. If wear or damage in the original arm is the cause of clunks, uneven tire wear, or wandering alignment, this replaces it.
Inspect suspension arms if you notice clunking over the rear axle on acceleration or bumps, uneven or accelerated tire wear, or alignment that won't hold. Diagnose the cause before replacing, as these symptoms can have other sources.
