Detailed Description
Delphi TC5255 is engineered for front upper suspension service where a worn ball joint can affect alignment, steering response, and tire wear. Delphi applies OE-level testing and material analysis to its aftermarket steering and suspension portfolio, with parts evaluated across extreme temperature ranges and salt-spray exposure to help verify durability. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It also cross-references OE-style part number 5C3Z 3049-BB and MOOG Chassis Products K500087. Compatible with Ford F-250 Super Duty and Ford F-350 Super Duty front upper applications where this part number is specified, including 5C3Z 3049-BB and K500087 interchange references. The Delphi TC5255 is a direct-fit suspension ball joint for service work that requires a bolt-on, front upper OE replacement.
Common Problems It Can Help Address
- Front-end clunking or popping over bumps
- Excessive play in the upper suspension joint
- Uneven tire wear caused by looseness in the steering and suspension
- Steering wander or reduced directional stability
- Inspection failure from worn suspension components
Installation Notes and Tips
Verify the mounting style, stud taper, and thread specifications before installation. This part uses a bolt-on design with three mounting holes, a tapered stud, and included mounting hardware and nuts. Because it is a non-greaseable assembly, routine lubrication is not required. Always inspect related suspension components and perform a wheel alignment after replacement.
Quality Assurance
Delphi tests this ball joint for OE-style performance under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt-spray testing. The brand’s OE engineering background supports dimensional accuracy and material consistency for aftermarket steering and suspension service.
