    My turbo 400 is leaking pretty good from the tail yoke. It almost looks like its coming from the inside of the yoke, not the outer seal. Can I fix this, and if so how?
    thanks in advance

    Mine leaks from the transfer case yoke, just haven't gotten around to fixing it yet. Unless it's pouring out of there I wouldn't worry too much about it. Just pay close attention to your fluid levels.

    If at first you don't succeed, failure may be your style...

    Ok you got me confused. If it's a 4x4 then it would be leaking out of the transfer case. Let us know exactly what you have. If it's a fixed yoke transfer case there is a seal in the center of the yoke. You assemble it Yoke, Seal, Washer , Nut. Those seals do get old and do fail. I have had to replace one on both of my trucks. It's a soft rubber washer more or less with grooves for the splines.
    If it's leaking at the adpator from the case to the tranny there are 3 seals that can fail. One is the seal to the adaptor, one is the O-ring to the tranny and one is the oil seal on the output. Haven't mess with a 400 so not exactly sure what way it goes.

    It's not my damn planet monkey boy!

    Yes its a 4x4, yes its coming out of the rear of the 208, and no its not leaking at the adapter from the case to the tranny.
    My fault for saying tranny, I just get into the habit of refering to the tranny and case as a single assembly, although it is not, sorry. So the seal-washer-nut thing is more than likely my fix.
    Thanks for the fix.

    well if it's a 208 it would be a slip yoke. Only seal should be a output seal.

    I just replaced my output seal today - I got fed up with the little ATF spot every time I parked, and I was changing the T-Case oil anyway. It cost the big $4.69 from Napa, and was cake to change.
