Notes:

• Teraflex recommend ball joints w/out knurls as they will not score the inner knuckle & open up the bore.
  
• Teraflex offered w/ knurls for ball joints w/ a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past.
