Notes:

• We recommend ball joints without knurls as they will not score the inner knuckle and open up the bore.
• We also offer ball joint with knurls for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed previously.
