Ok so this might sound dumb. I have an 07 Larait 4x4 5.v 17200 miles. I did have the rattling sound coming from the front end in April while I was on Leave. Thought it was the IWE's. Ford said at the time they could find no problam. I put the truck in storage when I went back. So when I got home in Aug the truck does not make the noise anymore. My wife had a leveling kit put on from 4Whell Parts. Ok thats the background. So now when I put the truck in 4x4 the light comes on, and I can tell the transfercase is working, but when I turn hard left or right I don't get the typical jerk from the tires. Can I get a 4x4 light if my hubs don't lock in. Thanks
