Detailed Description

Delphi TC1645 is engineered for front lower suspension service where ball joint wear can affect steering response, tire wear, and front-end stability. 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 is tested across extreme temperature ranges and salt-spray exposure to support durability in demanding road conditions. This part cross-references MOOG Chassis Products K7069 for the same application.

For Chrysler Fifth Avenue, Chrysler Imperial, Chrysler New Yorker, and Dodge Charger front lower suspension repairs, Delphi TC1645 provides a direct replacement option with the correct pressed-in format and serviceable grease fitting. It is also listed for Chrysler LeBaron, Newport, Town & Country, and Dodge Aspen, Magnum, and Monaco front lower positions.

What This Part Helps Address

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

Installation Notes and Tips

Verify the vehicle’s front lower position before installation and confirm stud thread size, taper, and pressed-in mounting requirements against the original part. Because this is a pressed ball joint, proper removal and installation tools are recommended to avoid damage to the control arm or surrounding suspension components. After installation, inspect alignment and suspension fasteners, and grease the joint if required by the service procedure.

Quality Assurance

Delphi uses OE-focused testing and dimensional analysis for its steering and suspension portfolio. TC1645 is evaluated for temperature extremes and corrosion exposure to support consistent performance in service.
