A dual disconnect differential assembly for four-wheel drive (4WD) vehicle is disclosed. This disconnect differential assembly connects/disconnects both output shafts of a differential assembly simultaneously from the respective universal joints of the drive assembly. Both output shafts are interconnected to provide simultaneous sliding along an axial direction. A clutch mechanism associated with the inboard side of each universal joint (which may be a constant velocity joint) and with the output shafts is provided for simultaneous connection and simultaneous disconnection of the output shafts from the outboard side of the universal joint. The dual disconnect differential assembly herein is simple, compact, and reliable. It overcomes the disadvantages associated with single axle disconnect mechanisms presently in use. It also provides a simpler, more compact, and more reliable dual disconnect differential mechanism than any such mechanism presently known.

The inline lubricator according to claim 3, wherein said handle engages said outer surface to limit the movement of said actuator. 5. The in-line lubricator according to claim 2, wherein said actuator extends through said first bore and includes a second end having a greater diameter then said first bore for retaining said actuator therein. 6. The in-line lubricator according to claim 5, wherein said spring biases said second end against said port in said first position. 7. The in-line lubricator according to claim 2, wherein said body has a third bore formed therein extending from a second outer surface of said body to said working passageway and a plug disposed in said second bore. 8. The in-line lubricator according to claim 7, wherein said actuator is axially aligned with said plug and said spring is operably disposed between said actuator and said plug for biasing said actuator toward said first position. 9. The in-line lubricator of claim 1 wherein said actuator further comprises a manually-operable actuator having a first portion extending from said body and is supported in said body for relative movement in response to manual manipulation of said first portion from said first position to said second position. 10. A pneumatic tool system comprising: a source of compressed air; a pneumatic tool selectively powered by said source of compressed air; a pneumatic line providing fluid communication between said source of compressed air and said pneumatic tool; and a lubricator including: a body having a working passageway formed therethrough, a fluid reservoir formed therein and a first bore formed therein to provide fluid communication between said working passageway and said fluid reservoir, said first bore having a first end terminating at said fluid reservoir to define a first port and a second end terminating at said working passageway to define a second port in fluid communication with said working passageway; an actuator having a transfer cavity formed in an outer surface thereof between a first seal and a second seal, said actuator extending through said bore and supported in said body for relative movement between a first position wherein said transfer cavity is positioned within said first port and at least partially disposed within said fluid reservoir, said second seal seals said second port to prevent fluid communication between said transfer cavity and said working passageway and a second position wherein said transfer cavity is positioned within said second port and at least partially disposed within said working passageway, said first seal seals said first port to prevent fluid communication between said transfer cavity and said fluid reservoir; a spring biasing said actuator towards said first position; and wherein movement of said actuator from said first position to said second position transports a predetermined amount of lubricating fluid in said transfer cavity into said working passageway. 11. The pneumatic tool system according to claim 10, wherein said body of said lubricator includes a second bore extending from an outer surface of said body through said fluid reservoir and terminating at said first bore, said actuator being slideably supported in said second bore. 12. The pneumatic tool system according to claim 11, wherein said actuator of said lubricator extends outwardly from said second bore and includes a handle coupled on a first end thereof for coordinated movement with said actuator. 13. The pneumatic tool system according to claim 12, wherein said handle engages said outer surface to limit the movement of said actuator. 14. The pneumatic tool system according to claim 12, wherein said actuator includes a second end having a greater diameter then said second bore for retaining said actuator in said second bore. 15.
