Hi Scotty, long time viewer, thanks for all of your work! Question: I have a 2013 VW Jetta TDI Sportswagen. For the past year now I have had a really bad vibration that can be felt most strongly in the passenger seat. I have had the car checked by a mechanic multiple times and they said everything looked fine. The only thing that may be causing it they said would be that one of the rims is a little bent. They showed me it, but I don't think that is it. The vibration is really bad at 60mph - 70mph. Sometimes it feels like the tires will fall off! Bolts are good, new tires have been put on, and I have tried using different wheels/rims, but the issue still persists. What is your take on this?

often worn motor or transmission mounts do that, or bent drive shafts

Thank you for your answer! Going to have those checked out
