I've developed a pretty severe leak from the front seal on my transfer case. In prepping to replace it I was doing a little research and am finding different sources some saying to use gear oil and some saying ATF. What fluid should I run??


I did put a new/used case in last fall and I do remember topping it off with ATF which it already had in it. I just want to use the right oil if I have to replace it any how.
