I'm saying this because when I first did this installation myself, I reused the shims and put everything back as it was, and after hours of putting everything back together - it whined! So I had to REDO everything again, take everything apart until I had everything setup well, backlash and preload adjusted exactly, and then it was OK.

Third time this was being done, was when I exchanged the final drive, but I was completely uninterested in doing that crap yet AGAIN, so I sent it to the specialist. And yes, it's completely silent.

So, don't be nervous about it, but in case you can really hear it and it kinda whines, then you might wanna have it checked.

Regarding "x-way" of the diff, that's cool. The main difference is that the 1.5 and 2 way especially, will lock up the diff when releasing the throttle and when coasting, which can make the car very tail happy unexpectedly. If you're into drifting, then maybe you really want that behaviour...but for normal LSD purposes, normal LSDs are better.
