Couple months ago I felt four or five clunks or bumps through the steering wheel when backing up and turning out of a parking space, kind of like I was backing over a small object. It now happens when turning forward from a stop. Just a bit like I was in 4wd on pavement but not as severe. (Yeah, I know what that feels like) Ideas? '02 F-350D 7.3, 4wd

 

How did this end up so far from the F350 and Powerstroke Diesel forums up above?
