4x4 issue

Hey folks, I have a 4x4 issue here. I have a 96 F350 7.3 4x4 manual trans with warn manual locking hubs. I just replaced all ball joints and decided while i was doing that I would drain and replace gear oil up front. So i did as well as putting a tube of friction modifier in as well. Now when i lock the hubs and pull the stick into 4x4 nothing happens in high range or low lock. wondering if this may be related? also a little more background is when 4x4 is engaged and truck moving the front driveshaft does turn as it should. the snow is coming so I would like to figure this thing out soon. thanks in advance.
