Help keep the rear wheel properly located with the Dorman - OE Solutions Lateral Arm 905-503, a direct-fit suspension lateral arm for the rear lower forward position. It fits many vehicles, among them the 2000-2013 Chevrolet Impala, 2008-2009 Buick LaCrosse and 2014-2016 Chevrolet Impala Limited. See the "Vehicles it fits" section for the full list.
A lateral arm links the rear suspension to the chassis and controls side-to-side wheel movement. This helps hold the wheel's position and alignment as the suspension travels. Dorman lists this arm for both the rear left lower forward and rear right lower forward positions.
- Direct replacement: Built to install and work like the factory arm on the listed vehicles.
- Reliable fit: Precision-engineered to mirror the original part's design and dimensions.
- Durable construction: Manufactured to strict standards from sturdy, safe materials.
- Rigorously tested: Backed by thorough quality control measures.
A lateral arm may need replacing if you notice clunking or rattling from the rear over bumps, uneven or early tire wear, loose or wandering handling, or an alignment that won't stay in spec. Because the arm is listed for both the left and right sides, replacing both together is recommended for even handling. Have the wheel alignment checked after installation.
