1. A vehicle differential assembly, comprising:

  • a differential housing rotatable about an axis;

    a first output assembly including a first side gear and a first output member, said first side gear disposed within said differential housing and being rotatable about said axis, said first output member coupled to said first side gear for rotation therewith;

    a second output assembly including a second side gear and a second output member, said second side gear being disposed within said differential housing and rotatable about said axis, said second output member coupled to said second side gear for rotation therewith;

    a helical pinion gear pair disposed within said differential housing and having a first helical pinion gear engaged with said first side gear and a second helical pinion gear engaged with said second side gear and said first helical pinion gear; and

    a first coupling assembly engaged with said first output assembly and including a coupling mechanism and a biasing member, said coupling mechanism extending through an opening in said first output member and being displaceable relative to said differential housing in a direction generally parallel to said axis, said biasing member engaged with said coupling mechanism and urging at least one of said first side gear and said first output member into frictional engagement with said differential housing.
