Delphi TD4325W Suspension Control Arm Bushing - Rear Upper

OE-Style Rear Upper Control Arm Bushing

Delphi TD4325W is a suspension control arm bushing built for rear upper applications on select Hyundai models. It uses a rubber-steel construction and standard replacement dimensions to support a precise OE-style service fit for Hyundai Sonata and Hyundai XG-series vehicles.

• Rubber-steel construction for controlled suspension movement
• Pressed mounting type for direct bushing replacement
• Black finish with standard replacement grade
• Inside diameter: 10.2 mm; outside diameter: 39.4 mm; length: 40.0 mm
• Rear upper position application
• Delphi TD4325W for OE-style steering and suspension service

Fitment and Application Details

This bushing is engineered for rear upper control arm service on 1999-2005 Hyundai Sonata, 2001-2005 Hyundai Sonata, 2001 Hyundai XG300, and 2002-2005 Hyundai XG350 applications. It also cross-references Beck/Arnley 101-6214 for the same application.

Delphi applies OE dimensional and material analysis to help maintain close compatibility between the original part and the replacement bushing. The design is tested across extreme temperatures and salt exposure to reflect demanding suspension conditions, making TD4325W a practical choice for Hyundai Sonata rear upper control arm bushing replacement and Hyundai XG350 rear upper suspension service.

Common Problems This Part Addresses

• Rear suspension looseness or excess movement at the control arm pivot
• Clunking or knocking from worn rear upper bushings
• Uneven rear tire wear related to suspension bushing wear
• Reduced suspension stability from deteriorated rubber-steel mounts
• Restoring proper control arm location after bushing wear

Installation Notes

TD4325W uses a pressed mounting design, so the old bushing must be removed and the replacement installed with proper suspension service tools. Inspect the control arm, mounting surfaces, and surrounding hardware before installation, and verify rear upper position fitment for the exact Hyundai Sonata or XG-series model year.

Quality Assurance

Delphi builds this replacement bushing using OE-focused engineering and material analysis, with validation that includes temperature extremes below -40 degrees C and above 120 degrees C, plus 720 hours of salt spray exposure. Part number TD4325W is made to support consistent fit and durability in everyday suspension service.
