I have an 05 TB. Just recently I have noticed the transfer case leaking. most noticable when I am towing my waverunner. It's very odd because it only leaks occasionally, meaning I can tow to the lake and it won't leak but return home several hours later and it will leak. I notice a leak because the is oil on my back window and on the waverunner. But like I said may show up sometimes but others not. I was told by a local shop that the transfer case seal was bad. But if this were the case wouldn't it leak all the time? Also when it was checked he said the oil was full, I ran it for several days and had someone else check it out, during those days it never showed a sign of leaking but when the 2nd person checked it he said that it needed oil and he put 2 qts in it. I trust the first shop I took it too, and have for years. Any suggestions on what this problem may be, before making the desicion to have the TC pulled and resealed?
