Detailed Description

Delphi TC393 is engineered as a front upper suspension ball joint for 1980-1986 Nissan 720, 1986-1994 Nissan D21, 1987-1995 Nissan Pathfinder, and 1995-1997 Nissan Pickup models. It is built from steel and uses a bolt-on mounting design with a threaded, tapered stud for secure suspension connection. Delphi applies OE dimensional and material analysis to help maintain proper compatibility between the replacement part and the original suspension geometry. The part is also tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. This part cross-references MOOG Chassis Products K9022 for the same application.

What It Helps Address

• Front-end looseness or play from a worn upper ball joint
• Clunking or knocking noises from the upper suspension area
• Uneven tire wear related to suspension joint wear
• Steering wander caused by excess joint movement
• Restoring proper suspension articulation on Nissan Pickup, Pathfinder, D21, and 720 models
