Abstract: A replacement ball joint assembly (10) adapted to be pressed into a previously used and possibly distorted receiving hole (26) in a suspension component such as a control arm (28). A socket housing (12) of the assembly (10) includes a plurality of generally annular, concentric knurls (36) each having a respective crest portion (38) and separated one from another by intervening relief grooves (40). The crest portions (38) of the knurls (36) may be tapered so as to provide a lead-in feature to minimize misalignment during a press-in installation operation.

Abstract: A construction of a cover for ball joint for application in connections of both angular and rotational movements of automotive vehicles. The cover is constructed with a boss in its outermost circumference so that when assembling the ball joint, the bearing flange that is inserted in the interior of the box, that is closed by the cover, does not burst. Moreover, the bearing is maintained fixed to the assembling place as it is desired, for the perfect operation of the ball joint. The cover constructed in this manner functions as a limiting piece in the assembling process, so that, even if too strongly pressed upon the bearing flange, it may burst only the outermost part of the bearing flange preserving its major part, that will be retained between the recess provided in the interior of the ball joint box and the space immediately posterior to the boss constructed in the outermost circumference of the cover, thus keeping the bearing fixed to its place.
