- Clunking or looseness from worn rear knuckle bushings
- Irregular suspension movement caused by deteriorated rubber
- Loss of alignment stability from bushing wear
Installation Notes
Verify the exact rear knuckle position for your vehicle before ordering. The listed fitment includes both upper and lower applications, and the correct position must match the application tab for the vehicle. Compare the original bushing dimensions and mounting location before installation.
