Decided to check fluid in the transfer case on my 91K5 I recently purchased. It was really low, so I filled her up. Next day I notice it is leaking all over the place. It's leaking from the top somewhere and where the main rear output shaft bolts to the main body. I go to check the cause and find this... I am assuming it is easier to get a new (used) case than get a new housing? It is a NP241 from a stock 91K5 with automatic, passenger drop. What other year transfer cases are a direct bolt in? What would you guys do? Any advice is greatly appreciated.
