[Trucker1967]

I remember some of the Ford F-150's having some sort of problem in the rear end and they were "re-indexing" the drive shafts, perhaps the frames in these Tundra's just need a perfect balance or a better one, I have seen they are recalling some of the drive shafts due to a hardness issue, but who is to say if that slipped through perhaps the balance is a problem as well??
