The LS chunk has spring packs and clutches. The spring pack pushes the gears against the clutches that are attached to a cage assembly. Both gears in the cage spin equally when both wheels are moving at the same speed. The clutches aren't really needed then. When they spin at a different speed the clutches and spring pack are slipping. They are designed to slip a little under low torque situations.

By running a different sized tires on the rear the clutch material may have worn out or the anti-friction additive is shot. Get the same size tires on it and service the rear adding the anti-friction additive and the LS might start working again.
