Guys, help me out! The driveshaft vibration at speed is driving me crazy.

[Josephrop]

Hello everyone!

My driveshaft is vibrating at high speeds, and it's becoming a real headache. Has anyone dealt with this before?

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

Remove it and take it to a balancing machine. It seems more reliable but involves a lot of hassle and costs more. I've also heard it can be balanced right on the car. This is done using special devices on a lift.

Has anyone faced a similar driveshaft vibration issue? How did you fix the driveshaft vibration, what method did you use, and why?
I want to buy a portable balancer Balanset-1A, like this for Electric Motor Balancing In this store https://www.ebay.com/itm/395459584162



Are there any tips or things to watch out for? I’d be thankful for any advice and recommendations!
