Hi i need a little help i just picked up a 91 rodeo from a guy at work. anyway it has some problems but the biggest one is the 4wd. He said it worked great when he first got it, but he went to use it after not useing it for a while and he said it would feel like it would engage but it would not. so dose anyone have a idea it would be great if you did thanks

 

So i have done some thinking and came up with auto hubs are not locking in. I can hear the transfer case engage, and the drive shaft moves. Has any one changed the auto huns to a manual locker?
