NOTE:
• We recommend Ball Joints w/out Knurls (# 3442002 or # 3440000) as they will not score the inner knuckle & open up the bore.
• We also offer Ball Joint w/ Knurls (# 3442022 or # 3440020) 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 in the past.
