Abstract: An articulated chassis work vehicle has an articulation joint rotatably coupling separate engine and equipment frames of the vehicle chassis. The articulation joint can have upper and lower joint assemblies. One or both of the upper and lower joint assemblies are constructed and arranged so that a corresponding bearing assembly is located between a single tab-like lug of each frame. In one arrangement, the articulation joint does away with clevis connections at both the upper and lower joint assemblies such that the available space within the articulation joint defined between the innermost upper and lower lugs is not reduced by additional lug and bearing components of either joint assembly.
