Should this be changed or do I just live with the whining noise? It doesn't bother me that much, I'm just worried if there's something that could break because of it.
The contact patch of the teeth is also excellent, I checked and I had nice full engagement. Also to say - I didn't change final drive ratio, pinion gear wasn't touched at all.

Edit - after reading online more about LSD whine + backlash - I'm quite sure I have exactly this problem. However, the backlash was good. Is it possible that the oil isn't good? I used OS Giken oil that I got with the LSD, and added per spec quantity in the diff housing.
