I have a 1999 Silverado Ext Cab 1500 Z-71 pickup that has been working just fine until recently when I was driving and went to put it into 4 low and I could hear when the xsfer case kicked but then I could feel there was no power in the front axle. What could cause this? I don't want to jump into this until I have some idea of what it could be thats causing this. Any advice on this matter would be greatly appreciated guys. Is this a common problem?How would I go about finding out. If there are any details on what you would need to get a better idea I'm at your disposal I just really want to get my chevy workin right. Thank you very much!
