Delphi TC2684 Front Lower Ball Joint

Delphi TC2684 is a standard replacement suspension ball joint built for front lower and front lower forward applications on select Audi and Porsche vehicles. It uses a pressed mounting design, steel construction, and a dust boot made from chloroprene rubber to support consistent steering and suspension movement.

Engineered with OE-focused dimensional and material analysis, this Delphi ball joint is built for direct-fit service on vehicles such as the Audi A4, A6, Q5, S4, S5, and Porsche Macan. The TC2684 part number is also a useful reference when comparing replacement options for the same application.

Key Features

  • Steel ball joint assembly with black finish
  • Pressed mounting type for front lower suspension service
  • Dust boot included to help protect the joint from road contamination
  • Standard replacement grade for OE-style service
  • Threaded tapered stud with 1.5 pitch and 14.0 mm thread diameter
  • Mounting hardware and nuts included
  • Grease fitting not included; non-greaseable design
  • Part number: TC2684

Detailed Description

Delphi TC2684 is a front suspension ball joint designed for precise fitment in OE-style repair work. Delphi subjects its steering and suspension components to extreme temperature and corrosion testing, including sub-zero and high-heat exposure plus extended salt-spray testing, to verify durability in demanding road conditions. The result is a replacement ball joint intended for vehicles that need accurate suspension articulation and stable front-end geometry.

This part cross-references Beck/Arnley 101-7822 and Mevotech Supreme MS10575 for the same application. It is listed for front lower, front lower forward, and front positions depending on the vehicle, including Audi A4, A4 Quattro, A5, A5 Quattro, A6, A6 Quattro, A7 Quattro, Q5, S4, S5, SQ5, RS5, RS7, allroad, and Porsche Macan applications. Use the TC2684 part number to verify the correct position before ordering.

What It Helps Address

  • Front-end looseness or play from a worn ball joint
  • Clunking or knocking noises from the lower suspension
  • Uneven tire wear caused by suspension joint wear
  • Imprecise steering response or wandering at the front axle
  • Restoration of proper suspension articulation on Audi and Porsche models

Installation Notes and Tips

  • Confirm the exact position before installation: front lower, front lower forward, or front.
  • Match the stud taper and thread specifications to the original part before pressing in.
  • Inspect adjacent control arms, bushings, and fasteners for wear during service.
  • After installation, perform a wheel alignment to verify suspension geometry.
  • For vehicle-specific fitment, check the application details for your Audi or Porsche model.

Quality Assurance

Delphi applies OE-focused engineering and extensive testing to its aftermarket steering and suspension portfolio. TC2684 is built with dimensional and material analysis to support compatibility with the original equipment design and to meet standard replacement expectations for front suspension service.
