Key Features

• Steel ball joint assembly with silver finish
• Pressed mounting type for front lower suspension locations
• Dust boot included with chloroprene rubber construction
• Standard replacement, non-adjustable, greaseable design
• Mounting hardware, nuts, and mounting hardware included
• Threaded stud with tapered end for secure suspension connection
• OE-focused dimensional and material analysis for fit consistency

Detailed Description

Delphi TC1078 is engineered as a front lower suspension ball joint for vehicles including the 2018-2023 Kia Rio, 2018-2022 Hyundai Accent, 2004-2009 Kia Spectra, 2005-2009 Kia Spectra5, 2003-2008 Hyundai Tiburon, 1997-2001 Hyundai Tiburon, and 1996-2006 Hyundai Elantra. It also covers rear lower applications on the 1999-2005 Hyundai Sonata, 2002-2005 Hyundai XG350, 2001 Hyundai XG300, and 1989-1994 Hyundai Sonata. This part number, TC1078, is built with a steel body, threaded stud, and tapered stud profile to match the suspension geometry used in these applications. Delphi validates parts through temperature extremes below -40 C and above 120 C, along with extended salt-spray exposure, to help maintain performance in demanding conditions. This part cross-references MOOG Chassis Products K500031 for the same application.

What It Helps Address

• Front-end looseness or play in the suspension
• Clunking or knocking from worn lower ball joints
• Uneven steering response caused by joint wear
• Suspension movement issues at the lower control arm connection
• Wear-related handling concerns on Hyundai Elantra, Sonata, Tiburon, and Kia Rio applications

Installation Notes and Tips

Delphi TC1078 uses a pressed mounting design, so proper removal and installation tools are required. Confirm the vehicle position before ordering, since this part is listed for both front lower and rear lower applications depending on the vehicle. Verify stud thread size, taper, and suspension orientation against the original part before installation on Hyundai Accent, Kia Spectra, or related fitments.

Quality Assurance

Delphi applies OE-based engineering, dimensional checks, and material analysis to support fit and function in aftermarket steering and suspension service. The part is tested for temperature extremes and corrosion exposure to reflect real-world operating conditions.
