I bought a MW aluminum shaft when they used to pay contingency it is 3.5 or 4" can't recall but it is bonded, with their yoke, been in car over 15 years now. I kept the steel one I made as a spare. I remember that it was no gain whatsoever. but if you have a vibration now, what is there to loose? Maybe some $ but you will have a spare!
