Common Repair Symptoms

• Front suspension clunking or knocking over bumps
• Excessive play in the radius arm mounting point
• Steering wander or reduced straight-line stability
• Uneven tire wear related to worn suspension bushings
• Visible cracking, separation, or deterioration of the original bushing

Installation Notes and Tips

Verify front suspension fitment by year, model, and position before installation. Inspect the radius arm, mounting surfaces, and surrounding hardware for wear or corrosion, and replace damaged components as needed. Because this is a press-fit suspension bushing, proper removal and installation tools help prevent damage to the arm or bushing bore.

Quality Assurance

Delphi applies OE-focused dimensional and material analysis to support correct aftermarket fitment. This bushing is tested for extreme temperature exposure and salt-spray resistance to reflect demanding undercar conditions, making it a practical replacement choice for Ford E-150, E-250, and E-350 front suspension service.
