Abstract
A limited slip differential for vehicular applications that eliminates chattering noise from the differential while maintaining seal integrity. This is accomplished by the use of a differential casing that includes at least a pair of fluid seals isolating a first chamber for bathing the respective differential components in a fluid lubricant appropriate to the contained components. A fluid lubricant, such as one containing a friction modifier is particularly suitable for the array of friction plates and pads of a disk pack, but can be detrimental to sealing elements, such as about the pinion gear. The separate chambers allows for the use of different fluid lubricants.
