Doing quite well, I have almost 3K miles on it now. The reman unit is just hard to beat in the easiness department... it even comes with a new axle nut. Install from start to finish it took me about 35 minutes and I barely even got dirty.
My only concern about a reman unit is that it may not be as strong as an OEM unit. Of course this is just 100% speculation. I don't really ever launch my car and I've never had wheel-hop (major axle killer) in any 'low traction' situation. Given the way the AWD system is setup in this car (equal length axles front and back) and the fact that my car will never see more than much over 350awhp it's not too much of a concern.
