• Wheel play or looseness from worn hub and bearing components
• Rough rotation or vibration from a deteriorated rear hub assembly
• Water intrusion or contamination affecting bearing service life

Installation Notes and Tips

Verify rear position fitment before installation on the Toyota Prius or Prius Plug-In.
