Hello all!

My driveshaft is vibrating at high speeds, and it's causing a lot of frustration. Has anyone had this problem before?

What's the best approach?

Remove the driveshaft and have it balanced with a machine. This method seems the most accurate but involves a lot of hassle – removing, transporting, waiting, and reinstalling.
Balancing the driveshaft without removing it. This approach involves special equipment to balance it on the car.

Has anyone encountered a problem like this? How did you solve the driveshaft vibration problem, which method did you choose, and why?
I want to buy a portable balancer Balanset-1A, like this for Turbine Rotor Balancing In this store https://www.ebay.com/itm/395385809563



Are there any recommendations or things to be aware of? I’d be thankful for any advice and recommendations!
