Detailed Product Information

Delphi TC5039 is engineered as a front upper suspension ball joint for Nissan Titan, Nissan Armada, INFINITI QX56, and Nissan Pathfinder Armada applications listed above. The pressed-in design, tapered stud, and included dust boot help support secure installation and stable joint movement in the suspension assembly. Delphi validates its steering and suspension parts through temperature exposure below -40 degrees C and above 120 degrees C, along with extended salt-spray testing to evaluate corrosion resistance. This part cross-references MOOG Chassis Products K80994 for the same application.

Common Problems This Part Can Address

• Front-end looseness or play from a worn upper ball joint
• Clunking or knocking noises from the front suspension
• Uneven tire wear related to suspension joint wear
• Steering wander or reduced directional stability
• Inspection failure caused by excessive suspension movement

Installation Notes and Tips

Confirm vehicle position before ordering, since this part is for front upper use only. Pressed ball joints require proper removal and installation tools, and the tapered stud should be seated and secured with the supplied castle nut and cotter pin. After installation, a professional alignment is recommended to verify suspension geometry and steering response.

Quality Assurance

Delphi applies OE-level engineering practices to its aftermarket steering and suspension portfolio, including dimensional and material analysis for fitment consistency. TC5039 is tested for temperature extremes and salt-spray exposure to help verify durability in demanding service conditions.
