Product Details

Delphi TC2320 is engineered for OE-level dimensional and material compatibility in the aftermarket steering and suspension space. Delphi subjects its steering components to extreme temperature testing and extended salt-spray exposure, then validates dimensions and materials to help maintain proper fit and function. This part cross-references MOOG Chassis Products K500225 and TRW JBJ789 for the same application. Use Delphi TC2320 when servicing front lower suspension wear on Audi A5 Quattro, Audi A5, and related Audi platforms listed below.

What It Helps Fix

• Front suspension looseness or play
• Clunking or knocking from the lower control arm area
• Uneven tire wear caused by worn ball joint movement
• Steering wander or imprecise front-end response
• Inspection failure from excessive suspension joint wear

Verify the vehicle build date and suspension configuration before installation, since several Audi applications are date-specific. Pressed-fit suspension joints require proper removal and installation tools to avoid damage to the control arm or joint bore.

Quality Assurance

Delphi applies OE-focused engineering to its aftermarket steering portfolio and validates parts through temperature cycling from below -40 degrees C to above 120 degrees C, along with 720 hours of salt-spray exposure. Delphi TC2320 is built for standard replacement service on Audi front lower suspension applications.
