Keep your front suspension located and steering tight with the Delphi control arm (P/N TC5019), a front left lower control arm and ball joint assembly that anchors the wheel to the chassis, lets the suspension travel, and uses its integrated ball joint to handle steering and ride motion. It fits many vehicles as a direct-fit replacement for the listed applications, among them the 2000-2012 Chevrolet Impala, 2005-2009 Buick LaCrosse and 2005-2009 Buick Allure — see the Buyer's Guide tab for the full list and engine-level fitment.
- Extreme-condition testing: tested below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- 100% inspected: every arm receives crack detection and ultrasonic flaw detection so materials match OE specifications.
- Micron-tolerance ball studs: studs machined to micron tolerances for durability and smooth joint operation.
- Robot-welded and protected: robotic welding for consistent quality, plus anti-corrosion protection for corrosion prevention and enhanced appearance.
Worn arm bushings or a loose ball joint can show up as clunking over bumps, uneven front tire wear, or wandering steering. If the original front left lower arm or its ball joint is the cause, this assembly replaces both in a single part.
