Chevybruce, I know you mentioned every component replaced but were all the items as mentioned by 52Carl addressed"Before I even think about touching the steering box, I remove and inspect the tie rod ends and the drag link ends. Then I check for play in the king pins"? On my 51 I pretty much did all the things Carl suggested including new kingpins and the old '51 3600 drives great.

I am running radial tires now which made a significant improvement especially on less than perfect paved country roads. If you're running bias ply tires and drive country roads they may well be the culprit.

Good Luck,

RonR
