My 4WD doesn't work on my 08 Superduty
I recently bought a 2008 Super-duty 6.4 Diesel. I tried out the 4 WD from the
buttons in the cab and my back tires started spinning when i tried to go
forward as if the front drive was in a bind. I then locked the manual hubs up
front and the truck moved in 4WD but makes a loud clunking noise as if
something is flopping around. I had the hubs redone but the problem is still
there. I'm pretty disappointed. Any ideas?
