Common Repair Symptoms

• Front-end clunking or knocking over bumps
• Loose or unstable steering feel
• Uneven tire wear from worn suspension geometry
• Excessive play from a failing ball joint or bushings
• Noise during braking, turning, or suspension travel

Installation Notes and Tips

Install Delphi TC3790 on the front left lower position only. Because the ball joint is press-in and mounting hardware is not included, verify the condition of related fasteners and service parts before installation. After replacement, a professional wheel alignment is recommended to restore suspension geometry on the Mazda 2.

Quality Assurance

Delphi subjects its OE-style steering and suspension parts to extreme temperature and salt-spray testing, along with dimensional and material checks to support consistent fit and durability. Part number TC3790 is built to align with OE expectations for the 2011-2014 Mazda 2 front suspension application.
