A hub assembly comprising a hub member (10), a flange (4) for wheel attachment, a double row bearing (2), and a constant velocity ratio universal joint (3), wherein the bearing has at least one inner bearing ring (13, 14) which is a separate component received on the hub member, and a connection between the hub member and a further part of the assembly is established by a welding and upsetting operation, and the inner bearing ring is engaged to hold it in position and to set the bearing as a result of such welding and upsetting operation. The welded and upset connection may be provided between the hub member and an outer member (15) of the constant velocity ratio universal joint, or between the hub member and flange. A weld bead formed by the welding and upsetting operation may engage the inner bearing ring either directly or indirectly, or a projection extending from the part welded to the hub member may engage the inner bearing ring. |
