87 D21 - 4x4 will not engage

Alright, I have a 1987 Nissan D21 4x4, 3.0L v6, and just recently I went mudding and soon realized my front tires would not engage into 4 wheel drive. I made sure the hubs were locked and made sure i was in either 4H or 4L, but the wheels still wouldn't turn. The gears changed to low and everything but just the tires weren't spinning. If anyone has had this problem and know what it is please get back to me in this thread...or if you have any clue to what it could be, please also respond.

Just recently I have noticed a really high pitch noise come from the front of the truck, I think, that occurs every time I increase the rpm's of the engine. However, once the vehicle warms up a little, it goes away. It doesn't make the noise when I drive regularly, but when I drive aggressively and put the rev's up there, it makes it.

The noise may be coming from the Front Axel but I'm not sure, as I haven't had enough time to jack of the truck and run it on the jacks to see the front axle's issues.
