Moog K6696 Ball Joint Moog instruction sheets contain specific information about press in ball joint orientation, where applicable. 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. Problem Solver patented cover plate design allows for tighter tolerances vs traditional cover plate designs, providing a more durable and extended life part. Full ball metal stud provides 36 degrees of smooth, consistent, rotational movement resulting in more responsive steering. 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. Greaseable socket design allows new lubricant to flush contaminants from the assembly, reducing corrosion and wear
