Reading up on the water pump and the transfer case issues this generation suffered, it seems the water pump is less likely to be an issue around 2012-2013 and on, as it is a double sprocket. I would still probably replace the water pump around 100k miles anyway but I was wondering if people have found that to be the case. As far as the transfer case, is that an issue that is more isolated to certain years or is it prevalent across all gen 1s? I'm looking at 2013-2015 model years but if they all have these issues I'll probably stay away.
