A hub assembly for a motor vehicle, comprising a hub member 1 rotatable in an outer bearing 3 race by balls 4, a constant velocity ratio universal joint 5 for driving the hub member and having an outer member 7 connected for torque transmission to the hub member by interfitting projection and recess formations such as circumferentially spaced teeth 16, is characterised in that the interfitting formations are provided on the respective components 1 and 7 by an incremental deformation (rotary forging or orbital pressing) process. The hub member and universal joint may be provided as separate units corrected by a bolt 19, having its head in a recess 20 in the hub member for easy access. The components 1 and 7 may be made from steel having a carbon content of 0.4% to 1.2%. <IMAGE>
