Detailed Description

Delphi TC413 is engineered as a front lower suspension ball joint for Volkswagen Cabrio, Golf, Jetta, Passat, and Corrado models listed below. It uses a bolt-on mounting style with three mounting holes, a steel housing, and a protective dust boot to support consistent suspension articulation. The assembly is a standard replacement design with no tapered stud, no grease fitting, and no adjustability.

Delphi’s aftermarket steering and suspension portfolio is built from OE safety technology and validated through extreme temperature and salt-spray exposure testing. That OE-based approach helps support dimensional consistency between the original part and the replacement component. If you are replacing a worn front lower ball joint on a Volkswagen Golf, Jetta, or Passat, Delphi TC413 provides a direct-service option for the specified chassis applications.

This part cross-references MOOG Chassis Products K9603 for the same application.

What This Part Helps Address

• Front-end looseness or play from a worn lower ball joint
• Clunking or knocking noises from the front suspension
• Uneven tire wear caused by suspension joint wear
• Steering wander or imprecise road feel
• Restoration of proper suspension articulation at the front lower position

Installation Notes and Tips

Verify the vehicle’s chassis break point before ordering, especially for 1988-1992 Volkswagen Golf and Jetta models noted as “From Chassis Serial Number 17J010565.” Confirm the front lower position and compare mounting dimensions before installation. Because this is a bolt-on assembly, inspect the mounting surface, fasteners, and surrounding suspension components for wear or damage before reassembly.
