Abstract
A clam-shell shaped differential housing including a lower portion for receiving the input shaft and the differential gearing, and an upper portion for enclosing the same within the differential housing. The clam-shell shaped differential housing allows for easy insertion and adjustment of the differential components. In addition, a lubricant reservoir may be formed in the area of the input shaft and pinion bearings to retain the majority of differential lubricant. The clam-shell shaped housing allows a pump to be easily positioned in the reservoir between the inner and outer pinion bearings to pump the lubricant from the reservoir to the differential components through channels formed in the housing. In this manner, the sump of the differential housing remains substantially dry. The pump may also be used to provide hydraulic pressure to a limited slip clutch assembly for the actuation thereof in conjunction with a valve control assembly.
