    I've got a slip yoke TH350/Np205 combo and have developed a bad leak. It looks to be running down the driveshaft and slinging everywhere under the rig. Would replacing the tcase tailshaft seal fix this or is there something else I need to check that may be causing the problem?

    It will help , but even when I did my old slip yoke transfercase it still got some atf coming out later . I think its what they do , seen it on many trucks with slip yoke rears :k5: :k5:

    I re-sealed my whole t-case and it does that too, I think my rear bearing may possible have some play in it, so that could cause the seal to leak.

    Pauly the thing is it really just started. Before it was a little damp and now its everywhere on the underside. I didn't know if I had done something to cause it or not.

    They will get worse after time , I know I need to do mine now ...again . I am sure theres a hard part reason for it , like a bearing or bushing , or worn slip yoke splines . But the new seal will work for a spell .... if ya don't want to tear into it . Grease teh slip inside and out before you slide it in :k5: :k5:
