2009 6.7L Electric 4x4 - I got stuck and put it in 4wd and the front tires did not spin. I put it in 4low and the front tires started pulling. when i gave more fuel the front drive shaft ujoint failed and broke the drive shaft. I have replaced the drive shaft and know the 4wd high does not engage. I can here the TC motor move and the light comes on and stays on. but the front tires don't pull. engage 4low and the front tires pull. if the truck is on a hill, i can go from 4 low to hi and the front tires stay engaged, but once the truck starts free rolling the front disengages. I am on a budget and can not afford a new TC trying to see if anyone else has had the same problem, so that way i know where to start before tearing it down and not having a truck to drive. Thanks
