Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC1946

$159.99

Description

Keep the front suspension tight and precisely located with the Delphi control arm and ball joint assembly, MPN TC1946. This front lower forward unit is a direct-fit replacement for the 2003-2010 Audi A8 Quattro, 2007-2009 Audi S8, and 2004-2006 Volkswagen Phaeton — see the Buyer's Guide tab for engine-level fitment.

The control arm locates the wheel and links it to the chassis, while the integrated ball joint allows the steering and suspension to move through their range. Clunking over bumps, imprecise steering, or uneven tire wear can be signs a worn arm or joint may need replacing; diagnose the cause before ordering.

OE-level testing: Delphi tests to the extreme, with parts withstanding temperatures below -40°C and above 120°C plus 720 hours of salt spray, backed by dimensional and material analysis for OE-to-aftermarket compatibility.
Verified materials: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
Machined ball studs: studs machined to micron tolerances for durability and smooth joint operation.
Robot-welded: consistent performance and quality, with anti-corrosion protection applied to each part.
