Transfer case rebuild, (How tough?)

I have a MK-100 T/C I'd like to re-bearing reseal it, how hard are they to do? Not much I have not done on a truck just never got into trans/ T/C type of stuff.

There not to hard. If you want to avoid the pit falls look for the posts by moparJa. He walks you through some of the things to look for.

Thanks will look that over!
