Detailed Description
Delphi TC4170 is a suspension ball joint for the front lower position on 1989-1994 Nissan 240SX models.

This part cross-references MOOG Chassis Products K9509 for the same application.
Common Repair Uses
- Restoring front suspension joint integrity on a Nissan 240SX
- Replacing a worn or loose lower ball joint
- Addressing front-end clunking or play during steering input
- Correcting uneven tire wear caused by suspension looseness
- Servicing a damaged dust boot or compromised joint seal
Installation Notes and Tips
Verify the front lower position and left-hand thread direction before installation. Because this is a press-in ball joint, proper suspension service tools are required for removal and installation. Confirm stud taper, cotter pin alignment, and castle nut seating during assembly, and inspect the surrounding control arm and hardware for wear before returning the vehicle to service.
Quality Assurance
Delphi subjects its OE-style steering and suspension parts to temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. The TC4170 is backed by Delphi’s OE-focused manufacturing and validation process for aftermarket replacement use.
