I have a '95 Blazer 4.3; auto trans; 140K miles. I recently noticed a leak where the front driveshaft comes out of the transfer case. I read somewhere to check the vent on top of the case to see if it or any of the hoses are plugged. My question is, I can see the vent but how the heck can you get to it? Also, does anyone know where the three hoses from the vent go?. Thanks in advance
