A vehicle driveline component with a differential case, a cross-pin, a differential gearset, and a retaining member. The differential case is rotatable about a first axis and has an annular wall member that defines a differential cavity. The cross-pin is received in a cross-pin aperture formed through a first side of the annular wall member. The cross-pin extends through the differential cavity along a second axis that is perpendicular to the first axis. The differential gearset is received in the differential cavity and includes a pair of side gears, which are rotatable about the first axis,and a pair of pinion gears that are journally supported by the cross-pin and meshingly engaged with the side gears. The retaining member is welded to the annular wall member and limits movement of thecross-pin relative to the differential case along the second axis in a direction toward the retaining member.
