I got mine done at Bennett, and you can't even tell in terms of noise levels. I've heard some people complain about whine after gear installs but I have none. I would also think about switching your rear end fluid to Royal Purple or Mobil 1 when they do the swap. Bennett is the only Royal Purple distributor in Saskatchewan. Go to talk to Steve (part's manager), tell him Graham sent you and he should hook you up with a good deal on the Royal Purple.
