    Has anyone had problems with their transfer cases leaking? My friend has an 04 with 66,000 on it and he says its leaking from up top.Anyone else ran into this problem and how to fix it?

    Had the same problem

    Had the same problem, check the tranny fluid level, if it is up over normal then you have a seal
    issue and need to pull the T-case, repair the problem, also change the tranny fluid and filters
    as the fluids and not compatable and will harm the tranny.... I also noticed oil spots on my tailgate weeks prior to finding my T-case empty when it went in for service...

    I found a new re-manufactured right from GM, 3/160 coverage, cost me 1800.00 installed...

    Goodluck and let us know what you find out....
