Electronic limited slip coupling having bolt on configuration

An electronic limited slip coupling comprising:

• an axle shaft that extends along an axle axis and is configured to meshingly engage a side gear of a differential assembly;
• a sleeve having a first set of splines projecting inwardly and meshed for engagement with the axle shaft;
• a support shaft having a second set of splines configured to mesh with a first housing of the differential assembly;
• a hydraulic control unit having:
• an accumulator housing portion that houses a biasing assembly and an accumulator piston, the accumulator housing portion forming an accumulator chamber with the accumulator piston, wherein the fluid pumped into the accumulator housing portion at least partially collapses the biasing assembly and introduces a pre-charge into the hydraulic control unit, wherein the biasing assembly is configured to expand and urge the accumulator piston in a first direction resulting in fluid being communicated from the hydraulic control unit and into the clutch assembly;
• and
• a motor that is configured to pump fluid into the accumulator chamber of the accumulator housing portion;
• a clutch assembly that receives fluid from the hydraulic control unit, the clutch assembly having a clutch pack operable to selectively interlock the sleeve and the support shaft;
• and
• a case that supports the electronic limited slip coupling as an assembled unit, the case having a flange that defines apertures for receiving fasteners that threadably couple the electronic limited slip coupling to one of a front transfer case and a front transmission.
