Detailed Description

Delphi TC588 is engineered for the front upper suspension location and built to match OE dimensional and material requirements. Delphi applies dimensional and material analysis to support fitment consistency between original equipment and aftermarket replacement parts, while the assembly is tested across extreme temperature and corrosion conditions. This part cross-references Beck/Arnley 101-3895 for the same application.

Compatible With 1986-1987 Mazda B2000, front upper; 1987-1993 Mazda B2200, front upper; and 1987-1993 Mazda B2600, front upper. If you are replacing a worn front upper ball joint on a Mazda B2200, Mazda B2600, or Mazda B2000, Delphi TC588 provides a direct-service suspension component for the listed applications.

Common Problems This Part Can Help Solve

• 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 instability or wandering caused by excess joint movement
• Inspection failure from damaged or deteriorated suspension components

Installation Notes and Tips

Verify the vehicle’s front upper suspension configuration before installation and compare the original joint, stud taper, and mounting pattern to the new part. Inspect the control arm, mounting surfaces, and surrounding hardware for wear or damage before assembly. Because this is a bolt-in design, proper torque and alignment checks after installation are important for correct suspension geometry.

Quality Assurance

Delphi tests steering and suspension components under severe temperature and salt-spray exposure conditions to support OE-level durability expectations. The brand’s OE engineering background and dimensional analysis help ensure the part matches the intended application for Mazda B2000, Mazda B2200, and Mazda B2600 front upper service.
