this is my first time posting so excuse me if I make some mistakes, so here is the problem the front tires spin wont spin when I put the truck into a4wd, 4hi or 4lo, I do not have a 4x4 service light and I can hear the 4x4 engaging underneath the truck, so the first thing I tried was I replaced my 4x4 front actuator and that didn't no fix the problem then I tried pulling fuse #8 under then hood then I jacked the front end of my truck up and put it into 4hi and 4lo and both of the front tires spun freely and I heard that no supposed to spin when doing so, I don't know what else to try and my truck doesn't make any grinding or scraping noises when driving
