Oh man, just looking at that disconnect reminds me of when I replaced mine!
It took me quite a while to remove the old one from my transfer case.
Within one year:
Between needing a new disconnect, replacing trans lines and a fuel neck, ongoing issues with the radiator fan, having to completely rebuild the trans, and the frame beginning to severely rust, I got tired of it "nickle and diming" me and traded it in for an Acadia. I do miss my Envoy, but seriously needed something more reliable. Strange, but I now find myself being bored at times and kinda wished I had something to work on...
