hey guys not a BMW noob, but maybe a x5..

couple of questions...

i get the debate on the tranny fluid to change or not...not sure there...


but the rear diff fluid...mobile 75-90?? can i put in 75-140 due to some mild towing?? what do we need for my front transfer case? i have 2001 x5 4.4

also thre seems to b a small leak on my transfer case as well?? any ideas?

brakes will be flushed with BMW dot 4

PS looks good..

Green coolant...not good..will get flushed. Any thing i am missing?? thanks for the help.
