I have sent mine back also.  He did do all the work under warrenty and shipped
the driveshaft back for free.  According to his machines the driveshaft is
fine.  His tests and everything may show it fine now but I wonder if it'll
start vibrating again once another 2-3k hit.  Well i'll be on the road then so
guess i'll just have to take it out if it does.  TODD AND PROVEN FORCE ARE
GOOD PEOPLE.  THEY DO GOOD WORK ITS JUST THAT ARES SEEM A BIT TRICKY FOR HIM.
THEY HAVE ALWAYS BEEN NICE AND HELPFUL WITH PROBLEMS.
