It cushions the shaft to absorb road shock and vibration, helps maintain proper alignment of steering components, and reduces friction to prevent premature wear. Over time the rubber material can degrade, causing steering play, clunking, or excessive vibration, so mechanics replace it during steering system overhauls or when these symptoms appear. This is a genuine Paccar part sold through Kenworth dealers, primarily intended for Kenworth Class 8 trucks.
