Description
Snap-On / John Bean 40211 Rear Slip Plate Ball (Plastic) for Alignment Racks
The rear slip plate balls are the small plastic bearing balls that sit beneath the rear floating slip plates on 4-post alignment lifts. Over time these balls crack, flatten, or go missing, causing the slip plates to drag or bind during rear toe and camber adjustments. Replace them when the plates no longer slide freely. Verify the ball diameter and quantity needed for your specific Snap-On or John Bean model before ordering.
