Delphi TC1271 Front Lower Forward Ball Joint

Delphi TC1271 is a standard replacement suspension ball joint built for the front lower forward position on select Honda Prelude and Acura Legend applications. It combines a steel body, pressed mounting design, and included dust boot, castle nut, cotter pin, and mounting hardware for a direct-service replacement.

Key Features

  • Steel construction with gray finish
  • Pressed mounting type for front suspension service
  • Standard replacement suspension grade
  • Dust boot included with chloroprene rubber material
  • Castle nut, cotter pin, cotter pin hole, and mounting hardware included
  • Threaded stud with tapered ends for secure steering and suspension connection
  • Grease fitting not included; non-greaseable design

Detailed Description

Delphi TC1271 is engineered as an OE-style suspension ball joint for the front lower forward position, with fitment for 1997-2001 Honda Prelude and 1991-1995 Acura Legend models. Delphi applies dimensional and material analysis to help maintain OE-to-aftermarket compatibility, and the part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. If you are replacing a worn front lower ball joint on a Honda Prelude or Acura Legend, Delphi TC1271 provides the correct pressed-in service format and the hardware needed for installation.

This part cross-references MOOG Chassis Products K500215 for the same application.

Vehicle Fitment

  • Fits 1997-2001 Honda Prelude, Front Lower Forward
  • Fits 1991-1995 Acura Legend, Front Lower

What It Helps Fix

  • Front suspension looseness or play
  • Clunking or knocking from the lower control arm area
  • Uneven tire wear caused by worn ball joint movement
  • Steering wander or imprecise front-end response
  • Inspection failure related to excessive suspension joint wear

Installation Notes

Delphi TC1271 uses a pressed mounting design and is intended for the front lower forward position on listed applications. Verify stud thread size, taper, and suspension orientation before installation, and inspect the surrounding control arm and related hardware for wear. Because this ball joint is non-greaseable, routine service is not performed through a fitting.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its steering and suspension portfolio. TC1271 is evaluated for temperature extremes and corrosion exposure, with dimensional and material checks used to support fit and function on the specified Honda Prelude and Acura Legend applications.
