Rich,
What I should have said, was that prior to installing the new drums and
rotors,I had them trued.
They were almost 100% on the money.

I am going to flip flop the drums tomorrow, and see if the problem
switches sides.

If not---oh well, back to the drawing board.

It's the pulsation thing that has me scratching my head.
If nothing is out of round, how come all the thump, thump, thump?

Now it is a me or it kind of thing. :>)
