Description

Keep your steering tight and your front suspension safely located with the Delphi Front Upper Suspension Ball Joint TC4277 — a direct-fit replacement for the 1998-2005 Hyundai Sonata, 2001 Hyundai XG300, 2002-2005 Hyundai XG350, 2001-2006 Kia Optima, 2004-2006 Kia Amanti, and 2001-2006 Kia Magentis. This Hyundai Sonata ball joint connects the front upper control arm to the steering knuckle, pivoting to allow suspension travel and steering motion. Worn ball joints may show up as clunking over irregularities, loose or wandering steering, or uneven tire wear.

Forged construction: made with high-quality forgings for increased strength and smooth operation.
Chloroprene rubber boot: improves durability and helps prevent premature failure.
Micron-tolerance machining: Delphi machines to micron tolerances for durable, smooth joint operation.
Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.

Delphi applies its OE steering expertise to this aftermarket part, testing to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray, with dimensional and material analysis for OE-level compatibility. This part installs at the front upper position; sold individually — replace both sides together for balanced steering feel.
