It was a broken axle. The bad part is the tranny had to be disassembled to get the broken piece out.
Thanks again for letting me run your car in the super challenge.
For those that didn't know it broke on my daughters second run on Sunday at the Packwood Pro. So she missed her last two runs or I should say last 3 as she never left the line and my son missed all of his Sunday runs as he was running in FP after us.
