Detailed Description

Delphi TC1689 is engineered for the rear upper position on 1986-1989 Honda Accord models. Delphi applies OE-focused dimensional and material analysis to help ensure proper fit and consistent suspension performance, and the part is tested across extreme temperature and corrosion conditions to verify durability. The Delphi TC1689 also cross-references Dorman - OE Solutions 520-646 for the same application.

Built as a press-in ball joint assembly, this component uses an alloy steel ball and carbon steel housing with a protective dust boot to help maintain joint integrity in everyday driving conditions. The threaded tapered stud, included cotter pin hole, and supplied castle nut support secure installation in the rear upper suspension location.

Common Repair Uses

  • Restoring rear suspension joint movement on a Honda Accord
  • Addressing looseness or play in the rear upper suspension
  • Correcting clunking or knocking from worn ball joint components
  • Replacing a damaged dust boot or corroded joint assembly
  • Recovering stable alignment and suspension control

Installation Notes and Tips

Fits 1986-1989 Honda Accord, rear upper. This is a press-in suspension ball joint, so proper removal and installation tools are required. Inspect the surrounding control arm and mounting bore before installation, and verify stud taper, thread pitch, and hardware fitment during assembly. Because this part is non-greaseable, routine inspection of the dust boot and joint condition is important during service intervals.

Quality Assurance

Delphi uses OE-based engineering practices and validates parts through temperature cycling and salt-spray exposure testing to support long-term durability. The TC1689 is built to standard replacement specifications for the rear upper suspension position on select Honda Accord applications.
