tranny fluid in transfer case

[Snafu]

I drained about 5 quarts of tranny fluid out of my d-20 tonight! What seals do I need to replace? Do I need any special tools? Do I have to remove the tranny from my Bronco or can I just drop the transfer case?

if you got 5 quarts out of your t-case, i'm assuming you have a C-4, right? you'll need to pull your t-case. there's a seal on the input shaft of the t-case, it's probably bad. there's a o-ring seal on the outside of the bearing retainer, you may as well replace that too.

i don't have a pic i can post, but i'm sure somebody does that'll help you.

as far as tools, simple hand tools are all you need. have a friend near by, that t-case is heavier than it looks!

Not to hijack , but is it best to split the adaptor section at the front or rear to reach the seal ?

at the rear, right at the t-case.

Hey 73 Stallion,Thanks for the info. It sounds easy enough

Hey Snafu, since you didn't say, did you get gear oil out too? Or was it only ATF?
Have you ever changed the gear oil before? The reason I ask is that over the years the Ford fluid recommendations have been all over the scale, from 50wt non-detergent engine oil, to gear lube, to ATF. So if you haven't checked it before, perhaps the P.O. just decided to use ATF on a recommendation?
I don't know if this is the case this time, but I just wanted to bring that up. Sorry if you've already gone through all that.

If that was the case, he shouldn't have had 5 quarts in the t-case. I think spec is something like 2.75 pints.
