They're manual hubs, one was kinda dry but both looked otherwise totally unworn, practically new. Put them back with lotsa grease. The 4wd lever itself had been removed and replaced, guy who installed my engine said it was in worng. It did shift much better but did nothing for the steering issue. We also checked the shifter action in the t-case, my mech said it shifted fine.

Actually "kinda dry" is better than "lotsa grease" in a manual locking hub. Too much grease can create a suction action preventing the hub disengaging or the grease can prevent it from fully engaging. I use either a very light film of grease or a spray of dry silicone lube in mine.
