Hey guys!

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

Now I'm trying to decide the best way to fix this:

Remove the driveshaft and have it balanced with a machine. This seems like the most reliable and precise method, but it's a lot of hassle – removing, transporting, waiting, and reinstalling it.
Balancing the driveshaft without removing it. Some folks manage this with special equipment without removing the driveshaft.

Has anyone used this method for balancing the driveshaft ? Let me know how it worked for you. I appreciate any advice in advance!
