Detailed Description

Delphi TC1619 is engineered as a front lower suspension ball joint for vehicles including the Chevrolet Cavalier, Pontiac Sunfire, and Oldsmobile Alero. Delphi applies OE-level dimensional and material analysis to help ensure proper compatibility between the original part and the aftermarket replacement. The ball joint uses alloy steel and carbon steel construction, a tapered threaded stud, and a protective dust boot to support dependable steering and suspension articulation in everyday driving.

This part cross-references Mevotech Supreme MK5273 for the same application. It is a direct-fit style replacement for front lower suspension service on many GM platforms from 1982 through 2005, including Chevrolet Malibu, Buick Skylark, and Pontiac Grand Am applications.

Common Problems This Part Can Address

• Front-end looseness or play from a worn lower ball joint
• Clunking or popping noises over bumps and turns
• Uneven tire wear caused by suspension joint wear
• Steering wander or reduced directional stability
• Inspection failure related to excessive suspension movement

Installation Notes and Tips

Verify the vehicle’s front lower suspension configuration before ordering, since fitment varies by year and model. Confirm stud thread size, mounting style, and position against the original component on Chevrolet Cavalier, Pontiac Grand Am, Pontiac Sunfire, and related applications. Professional installation and a post-repair alignment are recommended after suspension component replacement.

Quality Assurance

Delphi tests its OE and aftermarket steering components under extreme temperature and corrosion conditions, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. That validation process supports consistent service quality for TC1619 across its listed front lower applications.
