NOTE:

• We recommend ball joints w/out knurls (# 1355100) as they will not score the inner knuckle and open up the bore.
• We also offer ball joints w/ knurls (# 1355300) for ball joints with 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.
