Abstract
According to the invention, a prestress is applied to the bearing bush (17) to obtain a certain frictional torque between the latter and the spherical pivot while the locking ring (18) is placed on the bush (17); the punching tools (28) comprising a double die (30) are then actuated simultaneously in the direction of the socket (15) so as to deform the latter along two approximately circumferential and parallel zones located on both sides of the ring (18) to surround it without displacing it.
