    Hey, well ever since the last time i replaced my rear u joints my transfer case has been leaking atf fluid. Its not coming out of the main rear seal though because it seems to be dripping off of where the u-joint is. The rear seal is perfectly dry and dusty but all over my u-joint is soaked in fluid and drips on the ground over night. Is there anyway the fluid can get out there? Thanks Mike

    What kind of t-case is it? What year is your Blazer? If you have a 241, I know mine has always had a little leaking from around the slip yoke. Totally normal from what I can figure. Is it alot of fluid?

    Check the pressed in plug on the actual slip yoke. GM makes the slip yoke by making the splines through the entire shaft and then seals one end of it with a pressed in plug that can start leaking. Mine was, took it off and took it to a driveshaft shop, $25 later they had welded around the plug and haven't had a problem since.
