Abstract
Abstract A differential housing support assembly includes a pivot pin which projects from an end of the housing and is pivotally received in an annual ring of a support bracket which is bolted to a vehicle frame member. A cover plate is bolted to an end fact of the ring and includes a central portion which is directly engageable with an end of the pivot pin. Free play between the pivot pin and the cover plate is adjusted by controlling the number of annular shims placed between the annular ring and the cover plate.
