93 sidekick 4wd help
have a manual 93 sidekick and went to test out the 4wd today and it seems like the transfer case is locked up. Locked front hubs, put it in 4h and the thing won’t budge. Tried 1st gear, reverse, nothing. It feels like it wants to but it’s like it’s bound. Tried rocking it and it felt the same as an automatic in park. I unlocked the front hubs and still the same problem only now it feels like only the rear wheels are in a bind. Jacked up the front end and spun the tires in free, locked the hubs and same issue, tire turns a tiny bit, hear the hubs engage and tires lock. I checked the transfer case fluid and it is full and was changed a couple years ago. Not sure where to go from here and could really use some help
