Default When in 4X4 it bangs

Hey guys looking for an answer I have a 1999 ZR2 Blazer . My issue is when i put it in 4X4 i get intermittent bang in the front end, like the front end is coming out of 4X4 . Im going to pull the side case apart and look at the gear and shift fork . Has anyone else had this issue, and do i sound like im heading in the right direction by inspecting the front axle shift fork and gear ?
