Just a quick question, On a 2000 durango 4x4 with no mods, what is the max amount of water one can safely go through? Im new to the truck scene (had a hyundai accent before this) so I wanna get into off roading. Recently we had a huge rainfall and the roads flooded. Well, like a dumbass I went driving through it (about 1-2ft) acouple times. Today, i realized that may have not been a good idea without knowing about it. I saw that breather tube on someones post coming from the diff. is that something i should do? Im already planning on changing the diff fluids, tranny fluid and adjusting the "transmission bands" since i dont know the last time it had this done. Is there anything else i should add to my list that will help with my off roading adventures? Im slowly building my list of mods to do based on this boards suggestions, but lack of funds means i have to do the important stuff. sorry for this turning into sorta a long post.
