James, I own a 95 Blazer S-10 with 170,000 miles. It is a Great truck and
has been well taken care of! Recently there has been a slight growling
sound coming from the truck. My guess is the transfer case. My wife drives
the truck most of the time. She uses the push button 4W when needed. My
question, is there a possibility that it is hanging up between 2W to 4W?
If so, how do I fix it? One other question, my Chilton book said to use
Dexron III fluid in the transfer case. Is this true? I have never heard
of such a thing? The Chilton book said to check the fluid because it may
be low, which may explain the growling. I will check it tonight. I did
a visual and did not see any leakage from the transfer case.
Please answer ASAP!!!
Todd
Yes, Dexron III is used in the transfer case. I don't think it is hung between
gears. I think 175,000 miles without being serviced may have killed the transfer
case.
Please have a professional listen to it. It may not be what you think it
is! It is hard for me to “hear a problem” via email!:o)
Best wishes and thanks for the question.
