Detailed Description

This MOOG suspension ball joint, part number K5331, is engineered for front lower use on vehicles such as the Chevrolet Impala, Chevrolet Equinox, Buick LaCrosse, Pontiac Grand Prix, and Saturn Vue. It is a bolt-on replacement that uses a greaseable, powdered-metal gusher bearing design to promote grease penetration across the bearing surfaces, helping maintain smooth articulation in daily driving conditions. The K5331 is a practical choice when servicing worn front suspension joints on GM crossover, sedan, and minivan platforms.

This part cross-references Centric Parts 610.62013 for the same application.
