NOTE:

• These ball joints w/ knurls (# 1355300) are 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.

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