I'm not really sure how to. I know there are some how to's online but I get a bit nervous when doing my own maintenance. I change my oil and everything, even changed out the tranny fluid when I first got it, but I'm not to sure about how to drain the fluids on the rest of the car like the t-case, diffs, and so on.

 

Same drain and fill. No bleeding required on the t-case. If you did your transmission, the t-case should be cake

 

I have the same thing but mine is loud and comes from the right back of car i think my pump is about to die or my diff

 

Sounds like the torque transfer side of your rear diff
