Detailed Description

Delphi TC379 is built for front lower suspension locations on Acura Integra, Honda Civic, Honda CRX, Honda Prelude, and Honda Accord applications listed above. The ball joint assembly uses a threaded, tapered stud with a pressed-in mounting design to match the original suspension layout. Delphi applies OE-focused dimensional and material analysis to help maintain proper compatibility between the replacement part and the vehicle’s suspension geometry. The part is tested for temperature extremes and salt-spray exposure to support durability in demanding road conditions. If you are replacing a worn front lower ball joint on a 1990-1993 Acura Integra or a 1988-1991 Honda Civic, TC379 provides a direct-service solution for restoring suspension articulation and steering response.

This part cross-references MOOG Chassis Products K9385 for the same application.

What It Helps Fix

• Front-end clunking or knocking from worn suspension joints
• Excessive play in the lower control arm connection
• Uneven tire wear caused by loose suspension geometry
• Steering wander or imprecise road feel
• Inspection failures related to ball joint wear

Installation Notes

Press-in installation is required for this front lower ball joint. Verify the vehicle’s year, make, model, and suspension position before installation, and inspect the surrounding control arm and hardware for wear or damage. Because this is a non-greaseable design, it is intended for sealed-service use rather than periodic lubrication.

Quality Assurance

Delphi uses OE-based engineering and validation methods for its aftermarket steering and suspension components. TC379 is evaluated for dimensional accuracy, material consistency, temperature resistance, and corrosion exposure to support dependable service in front lower suspension applications.
