Detailed Description

Delphi TD1478W is a suspension control arm bushing for the rear lower forward inner location on select Kia and Hyundai vehicles. It is built from rubber and steel to provide the material balance needed in a suspension pivot point, helping maintain control arm alignment and reduce unwanted movement under load. This part is a direct-fit, press-in style replacement for vehicles including the 2004-2006 Kia Amanti, 2001-2006 Kia Magentis, 2001-2006 Kia Optima, 1998-2005 Hyundai Sonata, 2002-2005 Hyundai XG350, and 2001 Hyundai XG300.

Delphi applies OE-level dimensional and material analysis to aftermarket steering and suspension parts, and this bushing is tested across extreme temperature ranges and salt-spray exposure to verify material stability and corrosion resistance in demanding service conditions. If you are replacing a worn rear lower forward inner bushing on a Hyundai Sonata or Kia Optima, Delphi TD1478W provides the correct fitment profile for the listed applications.

What This Part Helps Address

• Excessive play in the rear lower control arm mounting point
• Clunking or knocking from worn suspension bushings
• Uneven tire wear caused by suspension movement
• Loose or unstable rear suspension feel
• Alignment drift related to deteriorated bushing material

Installation Notes and Tips

Delphi TD1478W uses a press-fit mounting design, so removal and installation typically require proper suspension service tools or a hydraulic press. Inspect the control arm, surrounding hardware, and adjacent bushings before installation, and verify the rear lower forward inner position matches the vehicle application before pressing the new bushing into place. Because mounting hardware is not included, reuse or replacement of related hardware should be confirmed during service.

Quality Assurance

Delphi tests suspension components for OE-style performance under extreme temperatures and extended salt-spray exposure. The brand also uses dimensional and material analysis to support fit consistency between OE and aftermarket parts.
