Leaking Transfer Case

So at my 5k service, I asked for them to check my drive line and lube if necessary as I've been experiencing a slight clunk upon coming to a full stop and sometimes on takeoff. I got a call from the dealer saying the service was done but that they noticed my transfer case seemed to be leaking fluid.

I've had my truck stuck pretty good once, midway up my right front wheel in a creek. Guessing I should I get my truck out of dealer custody ASAP and have this problem investigated elsewhere?

 

???WHY???

 

well...if its leaking and they are going to fix it under warranty, don't say anything about you wheeling and just let them fix it?
If they won't do so under warranty I guess take it elsewhere. Unless you want to line the dealers pockets some more.
