Detailed Description

Delphi TC1343 is engineered for the front lower forward suspension position and is built to match OE fit and material expectations for European vehicles. Delphi applies dimensional and material analysis to help ensure proper compatibility, and the part is tested across extreme temperature ranges and salt-spray exposure to support durability in demanding road conditions. This part cross-references MOOG Chassis Products RK80556 for the same application. Fits 2004-2005 Volkswagen Passat, front lower forward. Fits 2002-2004 Audi A6, front lower forward. Fits 2001-2004 Audi A6 Quattro, front lower forward, with 17in or 18in wheels. Fits 2003 Audi A8 Quattro, front lower forward, from chassis serial number 4D-X-005-501. Fits 2002-2003 Audi S6, front lower forward. Fits 2001-2003 Audi S8, front lower forward. Fits 2003 Volkswagen Passat, front lower forward, from chassis/VIN # 3B-3-072 001. Fits 2000-2002 Audi A8 Quattro, front lower forward. Fits 1998-2000 Audi A6 Quattro, front lower forward. Fits 2000 Audi A8, front lower forward. Fits 2000 Audi S4, front lower forward, to chassis # 8D-Y-080 000.

What It Helps Address

• Front suspension looseness or play from a worn control arm assembly
• Clunking or knocking noises from the lower front suspension
• Uneven tire wear caused by worn bushings or ball joint wear
• Steering instability or wandering at highway speeds
• Restoring proper suspension geometry after OE part wear

Installation Notes and Tips

Verify the vehicle’s chassis number, wheel size, and model year before ordering, since several applications have chassis-specific notes. Inspect adjacent suspension components, alignment settings, and mounting points during replacement. Because this assembly is not pre-greased and is not greaseable, it is installed as a sealed service part. Professional alignment is recommended after installation.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its steering and suspension parts. TC1343 is subjected to temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure, to support corrosion resistance and long-term service performance.
