An axle housing assembly for a work vehicle is adapted to be mounted in the work vehicle, and includes an axle housing and a disc-shaped member. The axle housing has a recessed portion for press fitting on an end thereof. The recessed portion is opened to a vehicle outer side, the recessed portion having a constant inner diameter. The disc-shaped member is press-fitted into the recessed portion, an outer peripheral surface of the disc-shaped member having a single reference dimension. A first region of the outer peripheral surface is arranged on an inner side in a press fitting direction and processed at a first tight fit tolerance range with respect to the reference dimension. A second region of the outer peripheral surface is arranged outwards of the first region and processed at a second tight fit tolerance range less than the first tight fit tolerance range.
