Transfer Case Leak Help *PICS*

    2004 Silverado 4x4, 4.3, 5 speed.

    I have what was a small leak from the transfer case. After driving it would drip a little bit until a say 3-4 inch stain formed. Months back I added fluid because I noticed the drip and i wanted to ensure the case was full. Fast forward to now and the leak seems to be a little worse, not sure though as I was driving at about 70mph for about an hour, and the 3-4 inch stain is from city driving.

    To me the fluid looks to be coming from the case bolt(s), and not the gasket seam itself. A friend said to back one bolt out at a time and apply grey rtv silicone to the threads, not sure about this. I dont really want a temporary repair just to have it start again when theres 2 feet of snow on the ground.

    If a shop visit is recommended, what do I call the repair, and what ballpark price am I looking at? (Im a college student)

    As promised, here are some pics to show what im talking about.

    Thread sealer on the bolts will probably only be a temporary fix. I would take it to a shop just to be on the safe side. Tell them that your transfer case is leaking fluid from the bolts, as for price, I'm not really sure but I would bet under $250.

    It looks like you may have the problem where theres a internal bearing that rides against the transfer case and wears a hole threw the case. There are kits out there to stop this from happening but once it has worn threw time for a t/case repair/replacement housing.

    Well for what its worth, I had RadAir take a look at it. They said that rear seal is indeed the cause of the leak. So it looks like ill take that rear cover off and apply RTV myself, rather then paying them to do the same thing.

    Okay guys another question. The bulk of the leak is coming from the 4x4 linkage. I was told by one place its an easy fix from the outside and no need to split the case. Yet another place says the gears will need to be pulled and the truck will be there for 2-3 days. Anyone know?
