You are NOT going to believe this one. Attached is photo of some sort of clamp or such, stuck in tire, My guess is when tire rotated it hit fender well, or concrete and clanged, would explain faster you went, more noise and in rear. TIER was NOT going down fast, still up till pulled it. NOTE I had jacked up rear wheels, spun by hand, in an out of gear, Then started truck and put in drive at idol, no noise. But noted tired going down and when I looked there was the beast stuck in tire, you can see size. As said NEVER heard a noise like that one, tire in shop and all seems well, will test drive when I put tire on, but strongly suspect this was issue. Old thing about check for obvious but it was on front right and road/truck noise seemed to sound like rear, more so with speed up noise as truck speed'd up. For once glad a nail in tire as lot cheaper fix. Thanks for interest and ideas, guess this one very rare issue like this or at least hope so.
