Delphi TC184 Suspension Ball Joint - Front Lower

Delphi TC184 Front Lower Ball Joint

Delphi TC184 is a front lower suspension ball joint built as a standard replacement for select Audi and Volkswagen applications. It uses a steel body, a dust boot, and bolt-on mounting hardware to support a precise OE-style service replacement for the front suspension.

Compatible with 1988-1991 Audi 80 and Audi 90, 1982-1985 Volkswagen Quantum, 1980-1983 Audi 4000, and 1981-1983 Audi Coupe in the front lower position, Delphi TC184 is a direct-fit option for common suspension wear repairs. This part number, TC184, is also referenced for related OE-style applications where the same fitment is required.

Detailed Description

Delphi TC184 is engineered for the front lower suspension position and built to match OE dimensional and material requirements for proper fitment. Delphi applies OE-focused testing and analysis to its aftermarket steering and suspension portfolio, including exposure to extreme temperatures and salt spray, to help verify durability in demanding road conditions. The ball joint assembly includes a dust boot and uses a bolt-on mounting design with a 2-hole pattern and 48.0 mm distance between mounting holes.

This suspension ball joint is a practical replacement for worn front lower joints on 1988-1991 Audi 80, 1988-1991 Audi 90, 1982-1985 Volkswagen Quantum, 1980-1983 Audi 4000, and 1981-1983 Audi Coupe. Delphi TC184 is a standard-grade replacement intended to restore suspension articulation and maintain consistent steering response in the specified applications. This part cross-references Mevotech Supreme MK9079 for the same application.

What It Helps Repair

• Front-end looseness caused by worn ball joint joints
• Clunking or knocking from the lower suspension area
• Uneven tire wear related to suspension play
• Steering wander or imprecise road feel
• Inspection failures tied to excessive joint movement

Installation Notes and Tips

Verify the vehicle chassis breakpoints listed for Audi 4000 and Audi Coupe before ordering, since those applications are limited by chassis number. Confirm the front lower position and compare mounting dimensions, including the 10.0 mm bolt shank diameter, 17.0 mm wrench size, and 28.0 mm thread length, against the removed part before installation. Professional installation and a post-repair alignment are recommended after suspension service.

Quality Assurance

Delphi uses OE-based dimensional and material analysis to support fit and function, and its steering and suspension parts are tested across extreme temperature and corrosion conditions. That OE-focused validation helps ensure the TC184 meets the expectations of a standard replacement suspension ball joint for the listed Audi and Volkswagen applications.
