    Which shaft isn't balanced? You made the shaft yourself after removing the pump?

    And yes, the truck will ride rough with no bed no weight:)

    I used to work at a place that had a big chevy like yours, we pulled a heavy gooseneck. It would toss you all over without the trailer.

    No, I had an engine rebuilder build the front section of shaft. I asked about balance. He said he takes great care to keep everything balanced, and has never had a balance issue. This shop has rebuilt several engines for me, I have a lot of confidence in them.

    I cant remember how many drive shafts i built over the years and nun were balanced. I have seen some realy messed up home made drive shafts that ran smooth. We had a truck with a problem like yours it had a bad pinion bearing.
