Hey guys!

I've come across a frustrating problem – there's a noticeable vibration at speed, and I've figured out it's coming from the driveshaft. The vibration is worse around 80-90 km/h. Based on some forum posts, it looks like an imbalance issue.

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

Take it off and balance it with specialized equipment. It seems more reliable but involves a lot of hassle and costs more. Some say you can balance it directly 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 device like this for Vibration Analyzer In this store https://www.ebay.com/itm/395459557061



Are there any tips or things to watch out for? I'd really appreciate any advice and recommendations!
