Help keep steering and handling under control with the Delphi control arm and ball joint assembly, MPN TC5817. This is the front left lower unit, engineered with Delphi's OE expertise, and it is a direct-fit replacement for many vehicles, among them the 2001-2003 Oldsmobile Aurora, 2000-2005 Buick LeSabre and 1998-2005 Buick Park Avenue. See the Buyer's Guide tab for the full list and engine-level fitment.
- Tested to the extreme: validated for OE performance below -40°C and above 120°C, plus 720 hours of salt-spray exposure.
- 100% inspection: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: machined to micron tolerances for durable, smooth joint operation.
- Robot-welded for consistent quality, with anti-corrosion protection applied to each part.
The lower control arm locates the wheel and, through its integrated ball joint, allows the steering and suspension to pivot. If a worn arm or ball joint is the cause of clunking over the road, loose or wandering steering, or uneven tire wear, this assembly replaces it. It is sold individually, and replacing both sides together is recommended.
