Delphi TC5040 Suspension Ball Joint - Front Lower

Delphi TC5040 Front Lower Ball Joint

Delphi TC5040 is a front lower suspension ball joint built as a standard replacement for select Nissan applications. It combines a steel body, pressed mounting design, grease fitting, dust boot, and included mounting hardware to support OE-style service on the front suspension.

Compatible with 1981 Nissan 810, 1982-1984 Nissan Maxima, and 1984-1988 Nissan 200SX in the front lower position, this Delphi ball joint is built for direct-fit replacement work. The TC5040 part number is also a useful reference when matching suspension components for these Nissan models.

Detailed Description

Delphi applies OE-focused dimensional and material analysis to its aftermarket steering and suspension portfolio, and the TC5040 follows that approach with a front lower ball joint engineered for fitment consistency. The pressed-in design, tapered threaded stud, and included dust boot help support proper suspension connection at the lower control arm location. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For Nissan 200SX, Nissan Maxima, and Nissan 810 front lower service, Delphi TC5040 provides a direct replacement option that aligns with OE-style dimensions and materials. The part number TC5040 is commonly used when sourcing a front lower ball joint for these specific Nissan fitments.

What This Part Helps Address

• Front-end looseness from a worn lower ball joint
• Clunking or knocking from suspension movement
• Uneven tire wear related to suspension joint wear
• Steering play caused by excess joint clearance
• Restoring proper lower control arm articulation

Installation Notes and Tips

Verify vehicle year, model, and front lower position before ordering. Because this is a pressed ball joint, installation typically requires proper suspension service tools and careful removal and installation procedures. Inspect the surrounding control arm, fasteners, and related steering components during replacement, and confirm the tapered stud and cotter pin hole alignment during assembly.

Quality Assurance

Delphi tests steering and suspension parts across extreme temperature ranges and extended salt-spray exposure to evaluate durability in demanding conditions. The TC5040 is backed by Delphi’s OE-oriented engineering process and material verification for aftermarket replacement use.
