Detailed Description

Delphi TC945 is engineered as an OE-style suspension ball joint for front upper use on vehicles such as the 1994-2002 Honda Passport, 1996-2004 Isuzu Rodeo, and 1996-1999 Acura SLX. Delphi applies dimensional and material analysis to help ensure proper OE-to-aftermarket compatibility, and this part is tested across extreme temperature and corrosion conditions for durability in real-world service. This part cross-references MOOG Chassis Products K90685 for the same application.

Use Delphi TC945 when replacing a worn front upper ball joint on compatible Isuzu Axiom, Rodeo, Rodeo Sport, Trooper, VehiCROSS, Amigo, Honda Passport, or Acura SLX applications. The part number TC945 is also useful when searching for an OE-style suspension ball joint replacement with the correct tapered stud and bolt-on mounting design.

What This Part Helps Address

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

Installation Notes and Tips

Confirm the vehicle’s front upper suspension configuration before ordering. Verify stud taper, mounting hole spacing, and bolt-on dimensions against the original part. Because this is a suspension joint, professional installation and a post-repair alignment are recommended after replacement. The TC945 includes mounting bolts and nuts, while castle nut, cotter pin, and grease fitting are not included.

Quality Assurance

Delphi validates this ball joint through temperature exposure below -40 degrees C and above 120 degrees C, plus extended salt-spray testing for corrosion resistance. The brand’s OE-focused engineering approach is backed by dimensional and material checks to support fit and function across the listed applications. Part number TC945 is built to meet standard suspension service expectations for front upper replacement work.
