R&R Transfer case - what else to replace?

[masospaghetti]

Hey all

I'm removing and replacing my transfer case with a rebuilt unit from TC Express in Spartanburg, SC. After I drop my old one out, any seals or gaskets that I should be replacing? (Output shaft seal, etc)?

Thanks all

I'd inspect it but I don't know if output seal can be replaced without removing shaft
Maybe consider replacing the u joints mostly for mileage sake and its already off...
Also would be a good time to replace pinion seal if needed...

The only gasket is the one on the extension housing, it is paper, use a thin skim of RTV on the paper if you like. The seals should all be new on your reman unit, so just the paper one at the extension housing.
