NOTE
We recommend ball joints w/out knurls (# 1353100) as they will not score the inner knuckle & open up the bore. Also offered w/ knurls (# 1353000) 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.
