Friends, I need ass

Hey everyone!
 
My driveshaft is vibrating at high speeds, and it's becoming a real headache. Has anyone had this problem before? 
 
Now I'm trying to decide the best way to fix this:
 
Remove the driveshaft and take it to a balancing machine. This seems like the most reliable and precise method, but it's a lot of hassle – removing, transporting, waiting, and reinstalling it.
Balance the driveshaft directly on the car. This approach involves special equipment to balance it on the car.
 
Has anyone tried  balancing their driveshaft  this way? Share your experience and results. I appreciate any advice in advance!
