Detailed Description
Delphi TC1235 is engineered for front lower suspension service on the Hyundai Sonata, Hyundai XG300, Hyundai XG350, Kia Magentis, Kia Optima, and Kia Amanti. Delphi applies OE-focused dimensional and material analysis to help maintain proper compatibility between the replacement part and the original suspension geometry. The ball joint uses a steel housing, a chloroprene rubber dust boot, and a tapered threaded stud to support secure installation and consistent steering and suspension movement.
Delphi tests steering and suspension components across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding conditions. This part cross-references MOOG Chassis Products K80621 for the same application. Delphi TC1235 is a practical choice when replacing a worn front lower ball joint on a 2001-2006 Kia Optima or a 1999-2005 Hyundai Sonata.
Common Repair Symptoms
- Front-end clunking or popping over bumps
- Loose or wandering steering feel
- Uneven tire wear from suspension play
- Excess movement in the lower control arm area
- Inspection failure due to worn ball joint components
Installation Notes
Verify front lower position, mounting hole spacing, stud taper, and thread pitch before installation. Inspect the surrounding control arm and fasteners for wear or damage, and replace any worn mating components as needed. Because this is a bolt-on design, proper alignment after installation is recommended to restore suspension geometry.
Quality Assurance
Delphi uses OE-based engineering and validation methods for its steering and suspension portfolio, including dimensional and material analysis plus environmental testing for temperature and corrosion resistance. That process supports consistent fit and service performance for the listed Hyundai and Kia applications.
