What would make a transfers engage 4wd in reverse but not drive? Is it junk?

 

anyone??? what kind of fluid so i need to get for the transfer case??

 

I'm pretty sure ATF but double check in the manual. And mines been doing it for a while an haven't had a problem

 

Your 4wd is not working like mine? I pull a trailer almost everyday right now with snow its a lot harder

 

Sorry to start this up again. But now with good snow i can better figure this out. When the 4wd disengages in forward motion i hear a clicking noise front what sounds like the tcase. In reverse it it makes a click a thud and its locked in still no 4low. Any idea on clicking noise
