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. MOOG engineered steel composition results in a stronger component. Full ball metal stud provides 360 degrees of smooth, consistent, rotational movement resulting in more responsive steering. Belleville washer preload provides lower torque and stud articulation with minimal axial clearance.
