Note:

• We recommend ball joints w/out knurls (P/N 3442002) or (P/N 3440000) as they will not score the inner knuckle and open up the bore.
• Also offered w/ knurls (P/N 3442022) or (P/N 3440020) 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.
