Detailed Product Overview

Delphi TC4184 is engineered as an OE-style suspension ball joint for the front upper location. It features a press-in design, a pre-greased assembly, and a rubber dust boot to help protect the joint from contamination. The threaded stud uses a tapered profile, and the included castle nut and cotter pin support a complete service replacement for the specified Hyundai Sonata and Hyundai Azera fitments. Delphi validates its steering and suspension parts through temperature and corrosion exposure testing to help maintain OE-level performance expectations in demanding conditions.

This part cross-references MOOG Chassis Products K500036 for the same application.

Common Repair Symptoms

• Front-end clunking or popping over bumps
• Excessive play in the upper suspension joint

Installation Notes and Tips

Fits 2006-2007 Hyundai Azera, Front Upper. Fits 2005-2007 Hyundai Sonata, Front Upper. Because this is a press-in ball joint, proper removal and installation tools are recommended to avoid damage to the control arm or joint bore. Verify left-hand thread direction, stud taper, and orientation before final assembly. Always confirm alignment after suspension service.

Quality Assurance

Delphi applies OE-focused testing and dimensional analysis to help ensure consistent fit and performance. This includes exposure to extreme temperatures and extended salt-spray testing to evaluate durability in harsh operating conditions.
