HELP... 4x4 Hub Problem

[ZachSyndy]

I'm in a 1991 ford ranger 4.0 v6, When i put my 4 wheel drive in and start going i hear a buzzing in the front drivers side hub, and it wont' lock in. but when i put it in reverse the 4 wheel will work. Then i go back to forward and i hear a big clunk and it still won't work and the buzzing goes when i go foward. It souds like per turn of tire there there is a few clicks, making it when i go faster the buzzing goes faster. Any ideas? thanks

Most people ditch the auto hubs and put the far more reliable manual units on. Look at this link for some troubleshooting tips:
