Jim, your thoughts....just live with it, or worry about it (or maybe fix it some day)?
I've never heard a noise like that from my car's LSD while backing up and turning so I don't know what to say on that.
The LSD internals look like they would work the same way in forward or reverse. Rotational torque would just be working on the oposite side of the helical cut ring and pinion gear teeth, and the small spider gears straight cut tapered teeth.

Sure it isn't a CV joint making the noise?
