Read this thread on offroadtb about the Awd disconnects and how it has issues cuz of the extra bending load on a lifted CV shaft seems to tend to fail the outside bearings rather quickly. To fix it they are doing the awd sleeve mod, my main question about this is, how quicky do you think the awd disconnect system might fail? Im a tiny bit worried about the current state of mine, mainly cuz most of the miles on the truck are not from me. So i dont know how many times the previous owner switched to 4x4 while moving, i know its bad to switch it while moving. Before i knew that i switched it into auto4 while driving, maybe two or three times. I do test my 4x4 system once a month to make sure its all good, everything feels good so far. Just a little paranoid i guess. Especially after all the BS we been thru lately.
