I have a hairline crack going down the back half of my transfer case housing. I know a lot of people use JB weld for a quick and sometimes long term fix, but instead of messing with that i just want to replace the back housing (the side with the drain plug).

Besides the transfer case housing, what other parts will i be needing? In some kits i've seen an output shaft seal, what else?

this is for a 2009 GMC Yukon, 4wd, TC is MP 3023/3024-NQH
