Detailed Product Description

The Delphi TC1515 suspension ball joint is a complete assembly designed to replace worn or damaged ball joints in vehicles such as the Lexus RX330, RX350, RX400h, ES300, ES330, and Toyota Camry, Highlander, Sienna, and Solara. Its steel construction ensures structural integrity under normal driving conditions, while the included dust boot helps prevent dirt and moisture intrusion, extending the life of the joint. The part features a threaded stud with a 0.551 inch diameter and 0.728 inch thread length, secured with a castle nut and cotter pin for safety and reliability. This ball joint is a standard suspension grade type, meaning it is designed to meet original equipment specifications without adjustability or grease fittings.

Common Applications and Problem Solving

• Restores proper steering control and suspension articulation
• Eliminates clunking or knocking noises from worn ball joints
• Prevents uneven tire wear caused by suspension misalignment
• Improves vehicle handling and ride comfort
• Addresses excessive play or looseness in front suspension components

Installation Notes and Tips

Installation of the Delphi TC1515 ball joint requires basic suspension knowledge and appropriate tools. Ensure the vehicle is securely lifted and supported before removal of the old ball joint. The included mounting hardware, castle nut, cotter pin, and washers simplify installation and help maintain factory safety standards. Since this ball joint is non-greasable, no additional lubrication is necessary beyond the factory-sealed dust boot. Verify torque specifications for the castle nut and mounting bolts according to the vehicle manufacturer’s guidelines.
