Detailed Description
Delphi TC392 is engineered for front lower suspension service on Nissan Pickup, Pathfinder, D21, and 720 applications listed in the fitment data. Delphi applies OE-level dimensional and material analysis to help ensure proper compatibility between the replacement part and the original suspension geometry. The ball joint uses a bolt-on design, steel construction, and a tapered stud to support secure installation in the front lower position. This part cross-references MOOG Chassis Products K9347 for the same application.
Common Problems This Part Can Address
- Excessive front-end looseness or play at the lower control arm
- Clunking or knocking from worn suspension joints
- Uneven tire wear related to suspension joint wear
- Steering instability or wandering at the front axle
- Visible dust boot damage or contamination at the joint
Installation Notes and Tips
Verify the vehicle’s year, make, model, and front lower position before installation. Confirm stud thread size, tapered stud dimensions, and mounting-hole spacing against the original part to ensure correct alignment. Because this is a bolt-on assembly, inspect the mounting surface, fasteners, and surrounding suspension components for wear or corrosion before reassembly. Professional installation and a post-repair alignment are recommended after suspension work.
Quality Assurance
Delphi tests steering and suspension components across extreme temperature and corrosion conditions, including sub-zero cold, high heat, and extended salt-spray exposure, to support OE-style durability in aftermarket service.
