Detailed Description

Delphi TC984 is engineered as a front upper suspension ball joint for 1995-2002 Land Rover Range Rover, 1998-2003 Land Rover Discovery, and 2004 Land Rover Discovery front upper applications through 06/30/2004. Delphi applies OE-focused dimensional and material analysis to help maintain proper part-to-part compatibility, while the component is tested across extreme temperature ranges and salt-spray exposure to reflect demanding undercar conditions. The result is a direct-fit suspension ball joint for Land Rover Discovery and Range Rover service work where precise steering and suspension articulation matter.

What It Helps Address

• Front-end looseness or play from a worn upper ball joint
• Clunking or knocking noises over bumps and rough roads
• Uneven tire wear related to suspension joint wear
• Steering wander or reduced front suspension stability
• Inspection failure caused by excessive ball joint movement

Installation Notes and Tips

Compatible with 2004 Land Rover Discovery, front upper, to 06/30/2004; 1998-2003 Land Rover Discovery, front upper; and 1995-2002 Land Rover Range Rover, front upper. Verify the stud taper, thread pitch, and mounting style against the removed part before installation. Because this is a pressed-style ball joint, proper service tools and alignment procedures are recommended after replacement. Delphi TC984 should be matched to the vehicle’s exact front upper suspension position before assembly.

Quality Assurance

Delphi backs this suspension ball joint with OE-oriented engineering practices, including dimensional and material analysis and environmental testing for temperature extremes and corrosion exposure. Delphi TC984 is built to standard replacement specifications for consistent service on Land Rover Discovery and Range Rover front upper suspension repairs.
