Claim 14:
15. A tandem wheel assembly for a work vehicle having a chassis and wheels, the tandem wheel assembly comprising:
a tandem wheel housing defining a center opening extending along a pivot axis and wheel end openings extending along associated wheel end axes, the tandem wheel housing being pivotally mounted to the chassis about the pivot axis, the pivot axis and the wheel end axes being parallel to each other, and each said wheel end axis being spaced longitudinally on opposite sides of the pivot axis, the tandem wheel housing having an exterior inboard wall configured to be closer to a fore-aft centerline of the work vehicle when mounted to the work vehicle, wherein the tandem wheel housing includes a cover fixedly attached to the exterior inboard wall thereof;
a center drive member disposed within the tandem wheel housing and rotatable with respect to the tandem wheel housing around the pivot axis;
first and second wheel end assemblies, each said wheel end assembly disposed at one of the wheel end openings, each said wheel end assembly including:
an input shaft mounted for rotation within the tandem wheel housing and extending through an opening in the exterior inboard wall,
a wheel end drive member mounted on the input shaft for rotation therewith,
a wheel end gear train coupled to the input shaft,
an output shaft coupled to the wheel end gear train and rotatable along the wheel end axis, and
a wheel end hub coupled to the output shaft for supporting one of the wheels;

a coupler between each wheel end drive member and the center drive member, wherein each wheel end drive member is driven by the center drive member; and
a brake assembly coupled to the tandem wheel housing and to the input shaft of at least one of the first wheel end assembly or the second wheel end assembly, the brake assembly being mounted to the input shaft between the exterior inboard wall and the cover.
