Delphi Suspension Ball Joint TC5255 Overview

The Delphi Suspension Ball Joint TC5255 is engineered for reliable performance in suspension systems requiring durable and precise components. Designed with high-quality materials, this suspension ball joint supports smooth steering and stable vehicle handling for various automotive applications.

• Ball material constructed from SAE 5140 alloy steel for strength and durability
• Housing made of carbon steel ensuring structural integrity
• Black finish for corrosion resistance and long service life
• Includes a dust boot made from chloroprene rubber (CR) to protect internal components
• Bolt-on mounting type with three mounting holes spaced 37.0 mm apart
• Tapered stud design with dual diameter ends for secure fitment
• Mounting hardware and nuts included for installation

Technical Details and Specifications

The Delphi TC5255 suspension ball joint features an 80 mm length, 100 mm width, and a height of approximately 104.3 mm (4.106 inches). The stud thread diameter measures 14.0 mm (0.551 inches) with a stud thread length of 22.0 mm (0.866 inches). The tapered stud ends have diameters of 16.2 mm (0.638 inches) and 19.5 mm (0.768 inches), providing a precise and secure connection to the suspension components. The dust boot is made from durable chloroprene rubber, which helps prevent dirt and moisture ingress, extending the life of the ball joint. This assembly is not greaseable and does not include bushings or washers.

Applications and Problem Solving

This suspension ball joint is suitable for vehicles requiring a bolt-on replacement part with specific mounting hole spacing and tapered stud ends. It is commonly used in applications where the original equipment requires a non-adjustable, non-greaseable ball joint assembly.

• Eliminates excessive play or looseness in the suspension system
• Reduces uneven tire wear caused by worn ball joints
• Restores proper steering response and vehicle alignment
• Prevents suspension noise related to damaged ball joints
• Protects suspension components from contaminants with the included dust boot

Installation Notes and Tips

Installation of the Delphi TC5255 ball joint requires a bolt-on mounting approach using the included mounting hardware and nuts. Ensure the mounting holes align correctly with the vehicle’s suspension arm, and verify the tapered stud fits securely into the knuckle. Since this ball joint is not greaseable, no additional lubrication is necessary beyond factory specifications. Proper torque specifications should be followed to maintain safety and performance.

Quality Assurance and Warranty

Delphi suspension components are manufactured to meet or exceed OEM standards, using high-grade materials such as SAE 5140 alloy steel and carbon steel housings. The TC5255 ball joint assembly includes a durable chloroprene rubber dust boot to protect against environmental damage. While specific warranty details are not provided, Delphi products typically come with a limited warranty covering defects in materials and workmanship.
