I have 2005 f150 xlt. Today I had truck stopped and in 4 hi, When I started the truck up and put it in drive it made a little clunk and I noticed the 4x4 light go out. The 4x4 hi light only comes on now when I start the truck. when I put the truck in 4x4 lo everything seems fine. The truck doesnt seem to go into 4x4 hi anymore. I appreciate any help as to what the problem could be Ie elctrical, mechanical etc
Thanks
