Swapped to wolverine hubs,something slipping/grinding

[dmartin1]

1978 k20 longbed camper special 350 small block turbo 350 automatic tranny.

it had the full time 4x4 front end,and after swapping it out for another front end with locking wolverine hubs,the only way it will grab into gear is in 4x4(hubs locked).
it wont ****ft into gear with hubs unlocked at all.

after getting into gear with the hubs locked,you can unlock them and drive 2wd for a short distance and it randomly slips out and starts making a slight grinding noise.

while trying to shift into gear in 2wd it makes the grinding noise and wont grab in gear and move.


whats going on?

any advice would be great,believe its a np205 transfer case
