Rod, Thanks for the thought, but the lead truck is a casting. The pivot hole in somewhat bigger than the post that it fits on (.201 vs .205) . There does not seem to be any rough edges on the hole,but I wonder if enlarging the hole by say .010 ( ten thousandths) would be beneficial or should the fit be tighter? It does seem that the binding occurs when the truck rocks to one side.
Thanks for the reply VERY MUCH Appreciated!
