Bell Never Aligned

I've seen plenty of TF's with one side of the converter/pump bushing worn through and a groove worn in the nose, usually the pump housing and reaction shaft were junk too. A fair number of them didn't make it 20,000 miles. The factory rep would usually OK replacing the case on the hope the error was on the transmission side of things. It's a lot more difficult checking for concentricity of a trans case than it is with a bell, and the rep never asked me to check one. I have no way of knowing how many of those failed again in the same way at a later date.
