Moog K7467 Ball Joint Problem Solver powdered metal gusher bearing design enables grease to flow through the bearing to the stud for reduced friction and enhanced strength and stability. An enlarged ball joint receptacle in the control arm can cause a loose ball joint fit. Moog Problem Solver design includes an oversized housing for a more secure fit. Full ball metal stud provides 36 degrees of smooth, consistent, rotational movement resulting in more responsive steering. Moog engineered steel composition results in a stronger component Greaseable socket design allows new lubricant to flush contaminants from the assembly, reducing corrosion and wear Loose or worn chassis parts can lead to premature tire wear
