Guys, help me out! I'm dealing with driveshaft vibration when driving fast.

No eBay APP ID and/or Cert ID defined in Kunena configurationHi everyone!

I'm dealing with a frustrating problem – 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. From what I've read online, it's likely an imbalance problem.

What should I do?

Take the driveshaft off and have it balanced at a shop. It might be the best solution, but it's inconvenient and pricey. I've heard it can also be balanced while still on the car. This is done using special devices on a lift.

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 Grinding Machine Balancing In this store



Are there any recommendations or things to be aware of? I'd really appreciate any advice and recommendations!
