Hey Don, good to see you on the board!
Anyway, one this I thought I might add as I think its on topic...I have been noticing lately that I have a creeking noise in the front end...Took it to a local front end shop to have it checked out. EVERYTHING checked out ok (Ball Joints, Drop Bracket Bolts, Tie Rod Ends, Engine Cross Member Etc....)
Guy took the truck back off the rack and had me get in and start it...Without moving at all I turned the wheel back and forth (not much) while he listened....it was creeking slightly as I went back and forth. He told me that about a week ago he had an F-350 in the shop and found that the frame was cracked behind gear box...I had never heard of that before, but thought it MIGHT be just another to check out if you have th box off anyway. My steering is great but I am going to pull the box this weekend and see what I see.
