Was it the worn var causing the problem? I recently started noticing a vibration at 50mph and above. Now it is worse and starts at 40mph and above
Its a woooooooom-wooooooooom-woooooom-wooooooom-woooom-woooom-wooom-wooom-woom-woom-woom-wom-wom-wom

If i accelerate to 40 and hold it there the vibration starts as long woms and shortens to short woms

Hard to explain with woms lol

I know what you mean when you describe the woms. :smile:

Worn belt and rollers cause the woms :thumbwink:

Never did completely explain the thrum. Looking at your Vario Video, it seems the low-tension side of the drive belt does a lot of flapping around. Maybe that's it?
