Hello all! 
 I've encountered a really annoying issue – there's a noticeable vibration at speed, and I discovered that it's due to the driveshaft. It's especially bad at certain speeds, like around 80-90 km/h. After reading through some forums, it seems like it's probably an imbalance problem.  
I'm considering the best method to solve this:  
Remove the driveshaft and have it balanced with a machine. It appears to be the most reliable way, though it's a lot of hassle – removal, transport, waiting, and reinstalling. 
Balancing it directly on the vehicle. This approach involves special equipment to balance it on the car.  
Has anyone faced a similar driveshaft vibration issue? How did you solve the driveshaft vibration problem, which method did you choose, and why? 
I want to buy a device like this for
