Delphi TD4479W Suspension Control Arm Bushing - Front Upper

Delphi TD4479W Front Upper Control Arm Bushing

Delphi TD4479W is a front upper suspension control arm bushing built with steel and rubber for OE-style replacement performance. It is a press-in bushing with standard replacement grade construction for service on select Isuzu i-280, i-290, and i-370 applications.

Key Features

• Steel and rubber construction for controlled suspension movement
• Press-in mounting type for front upper control arm service
• Black finish
• Inside diameter: 14.5
• Outside diameter: 42.7
• Length: 45.1
• Standard replacement grade
• Delphi OE-focused dimensional and material analysis for fit consistency

Application Details

This Delphi suspension control arm bushing is engineered for front upper placement and matches the OE-style dimensions needed for proper suspension geometry. It fits 2006 Isuzu i-280, front upper; 2007-2008 Isuzu i-290, front upper; and 2008 Isuzu i-370, front upper. The TD4479W part number is also a useful reference when comparing replacement options for these Isuzu models.

Delphi applies OE-level testing to aftermarket steering and suspension components, including exposure to extreme temperatures and extended salt-spray testing. That approach supports material durability and dimensional accuracy for vehicles that rely on precise bushing fitment. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive play in the front upper control arm
• Clunking or knocking from worn suspension bushings
• Imprecise steering response caused by bushing wear
• Uneven suspension articulation from deteriorated rubber
• Fitment issues when replacing an OE-style front upper bushing

Installation Notes

TD4479W is a press-in bushing, so proper removal and installation tools are required for service. Verify the front upper position and confirm dimensions against the original part before installation on Isuzu i-280, i-290, or i-370 models. Clean the control arm bore thoroughly and inspect the arm for wear or deformation before pressing in the new bushing.

Quality Assurance

Delphi uses OE-focused engineering, dimensional analysis, and material validation to support consistent aftermarket fit and performance. The part is tested for temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure, to evaluate durability under demanding conditions.
