ABSTRACT:
A power transmission device includes a housing, a differential assembly having a case and a bearing assembly rotatably supporting the case within the housing. A preload is applied to the bearing assembly along a load path. A shim is positioned in the load path with the bearing assembly. The shim is constructed at least in part from a material having a predetermined coefficient of thermal expansion such that the shim is operable to compensate for different rates of thermal expansion in the components within the load path to maintain a desired bearing preload or a range of operating temperatures.
