I swapped it out. Works fine now.

Ok new issue. I swapped in the new transfer case. Same part number etc. Prior to this the old one even in such bad condition would engage 4wd. 4x4 light on instrument cluster would light up as well. Now no light. Not certain 4wd high is engaging. 4 low feels like it engages. Would the switch on...

I will attempt to document the rebuild of this unit. I picked up a low mileage used one to install because its my DD. But plan to rebuild this one as a spare. They are not easily obtained in my area.
