Delphi Suspension Control Arm P/N:TC9519
Help keep the rear suspension located with the Delphi control arm TC951, a direct-fit replacement for the 1996-2002 Audi A4 Quattro and 2000-2002 Audi S4. It installs at the rear lower rearward position, locating the wheel and pivoting on its ball stud so the tire tracks correctly through suspension travel. See the "Vehicles it fits" section for the full engine-level applications.
Delphi builds this arm on its OE expertise, with dimensional and material analysis to match the OE part:
Worn control arms and their joints can show up as clunking on bumps or over uneven pavement, wandering steering, or uneven tire wear. If a failed arm or ball joint is the cause, this replaces it. Replacing both sides together is recommended for balanced suspension geometry, and have the alignment checked after installation.
