Driveshaft without weight

[jown]

I've seen a lot of different adverts with some including weights on the driveshaft and other without

I was getting a vibration from my drivers side and I replaced the driveshaft (both dont have weights)

My passenger side has a weight but the other side to the pair I purchased does not

I am guessing this is the reason I am getting a vibration when sitting at 70mph?

Wheels are balanced

Thanks

Would like to also add that the vibration only started happening 2 months ago from what felt like the driver's side

The driver's side never had a weight on it and I never had these issues
