Moog K5335 Ball Joint Moog split bearing Problem Solver technology eliminates excessive radial deflection often experienced with high lateral loads, which are caused by taller ride heights and vehicles with a higher center of gravity. 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. The ball joint assembly maintains maximum ball to bearing contact for greater load carrying capability. Moog engineered steel composition results in a stronger component Full ball metal stud provides 36 degrees of smooth, consistent, rotational movement resulting in more responsive steering. 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 Use on 1997 - 1999 S10 trucks Use on 4-wheel drive vehicles Ball joint is greasable Dust boots included Improves chassis performance and durability
