December 21, 2010Hi All - I`m hoping someone can help me out. I tried to put my truck in four wheel drive last week after the snow storm. I heard it engage, the light on the dash turned on and I thought all was good. That is until my rear end started sliding all over the place. Turns out everything worked but the actual four wheel drive. I have done some searching around the net and it sounds like the problem is a broken/worn shift fork. Has anyone else had this problem? Can you give me an idea on how much this is going to cost to fix? Or does it sound like something else to you?? Thanks!
