Detailed Description
This Dorman suspension ball joint, part number 533-343, is made for front lower suspension service where OE-style fit and steering articulation are required. The steel body, rubber dust boot, and threaded stud construction support a direct replacement approach for vehicles that use this specific front lower joint design. It cross-references Delphi TC659 for the same application. Use 533-343 when servicing front lower suspension wear on 1991-1994 Mercury Capri, 1986-1989 Mazda 323, and 1987-1989 Mercury Tracer.
What It Helps Fix
- Front-end looseness or play from a worn lower ball joint
- Clunking or knocking from the front suspension
- Uneven tire wear related to suspension joint wear
- Steering instability caused by excess joint movement
- Inspection failure from a damaged or worn front lower joint
Installation Notes and Tips
Verify vehicle year, make, model, and front lower position before installation. This part uses a bolt-in mounting type with a threaded stud and cotter pin hole, so confirm the original hardware layout and wrench size match the application. Because the grease fitting is not included and the joint is not greaseable, no periodic lubrication point is provided. For best results, inspect related suspension components during replacement on Mazda 323, Mercury Capri, or Mercury Tracer applications.
