4 wheel drive will not disengage all the way
New to this site. I have a 2004 f-150 four wheel drive. Started to notice a roaring noise in front end. After jacking up the left front end and spinning the tire I hear a clicking noise. Replaced hub assembly same problem. However if I put it in four wheel drive and turn off, the clicking go"s away. When I shut the truck off a few seconds later after spinning the tire the clicking comes back. Even if you do this process while driving you still hear the roaring. Any help would be great.
