Hello all, I filled up my transfer case last night and it seemed like it just came right out the rear output(by morning). Is that the slip yoke? If so is there a seal that needs to be replaced? It's an NP208. It has been leaking a little, but when I came out this morning there was a puddle of ATF under my truck. I thought I read something here about this problem, but when I did a search I found nothing. '84 K5 Chevy in my blood.
