摘要：A replacement ball joint assembly (10) adapted to be pressed into a previouslyused and possibly distorted receiving hole (26) in a suspension component such as acontrol arm (28). A socket housing (12) of the assembly (10) includes a plurality ofgenerally annular, concentric knurls (36) each having a respective crest portion (38) andseparated one from another by intervening relief grooves (40). The crest portions (38) ofthe knurls (36) may be tapered so as to provide a lead-in feature to minimizemisalignment during a press-in installation operation. The knurls (36) are preferablysofter than the control arm material so that they yield during press-in rather than furtherdisfiguring or enlarging the receiving hole (26). Displaced material from the crestportions (38) of the knurls (36) flows into the relief grooves (40).
