Abstract: The present invention relates to a vehicle component support carriage for maneuvering heavy engines, transmissions, or vehicle rear end differentials while those components are being serviced. The apparatus includes a wheeled carriage that supports an enclosed drive apparatus used to incrementally rotate the heavy component for servicing, replacing parts or cleaning the component. The apparatus support apparatus is arranged so that a removable portion of it is aligned and secured to the first engagement member before the heavy component is assembled to the wheeled carriage on a journaled shaft that is operatively connected to the drive apparatus. The removable portion of the support apparatus is pre-disposed with a pattern of mounted apertures or hardware that will present a balanced assembly when loaded on the carriage support apparatus. A second variation enables servicing of two engines at once, both engines being balanced and supported similarly.
