Detailed Description

Delphi TD4366W is designed for rear upper control arm service where the original bushing has worn, cracked, or lost its ability to isolate suspension movement. Delphi applies OE-focused dimensional and material analysis to help ensure the aftermarket part matches the original application closely. The bushing is built from rubber and steel and is tested for temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure for corrosion resistance validation. This part cross-references Ford 5L8Z55000A for the same application.

Common Repair Symptoms

• Rear suspension clunking or knocking over bumps
• Excessive play in the rear upper control arm
• Uneven tire wear related to suspension movement
• Loose or unstable rear-end handling
• Visible cracking or deterioration in the original bushing

Installation Notes

This is a pressed bushing, so removal and installation typically require suspension service tools or a professional press setup. Inspect the control arm, surrounding bushings, and mounting points before installation, and verify rear upper fitment against the vehicle application before service. Delphi TD4366W is used on 2001-2008 Ford Escape, 2001-2006 and 2008 Mazda Tribute, and 2005-2008 Mercury Mariner in the rear upper position.

Quality Assurance

Delphi validates this suspension bushing through OE-oriented dimensional and material analysis, plus environmental testing that includes extreme temperatures and salt-spray exposure. That testing supports consistent fit and durability expectations for rear upper control arm replacement service.
