Detailed Description

Delphi TC584 is a standard replacement suspension ball joint engineered for the rear upper position. Delphi applies OE-level dimensional and material analysis to help ensure proper fit and consistent performance, while its testing process includes exposure to extreme temperatures and extended salt spray conditions. This part is built for vehicles that need a precise rear suspension connection, including 1995-1999 Land Rover Discovery, 1997 and 1995 Land Rover Defender 90, 1993-1995 Land Rover Range Rover, and 1993 Land Rover Defender 110. The Delphi TC584 also cross-references Beck/Arnley 101-0289 for the same application.

Common Repair Symptoms

• Rear suspension looseness or play
• Clunking or knocking from the rear upper suspension area
• Uneven tire wear caused by worn suspension joints
• Imprecise rear suspension alignment or handling response
• Visible dust boot damage or joint wear

Installation Notes and Tips

Verify rear upper fitment by year, make, and model before installation. This bolt-on design uses two mounting holes and a tapered stud, so proper torque and alignment of the mounting points are important. Inspect the surrounding suspension components, fasteners, and mounting surfaces for wear or corrosion before replacing the joint. Part number TC584 should be matched to the vehicle application listed for 1993-1999 Land Rover rear upper suspension service.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its aftermarket steering and suspension portfolio. This ball joint is tested for temperature extremes below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray to evaluate corrosion resistance and durability.
