Will this cause vibration?

I found those scratches on rear drive shaft. This is from last weekend's Off-roading in Snow. No, snow didn't do this. Rocks under the snow did this.

I visually checked the shaft and didn't find any big dent or damage. Will those scratches cause the shaft to be out of balance??

It looks as though there may be a missing counter weight to the far right (rear), just ahead of the Ujoint. Those scratches appear to be made by a rock as you crossed it. Any chance that had the full or much of the weight of the vehicle was on the drive shaft at any point?
That would do your shaft a great deal of benefit.
I'd have to concur that the missing weight alone should trigger a rebalance.

I've been worrying about this a bit on my own truck. It spent 6 salty years on German roads. The shaft balance weights have rust between the individual plates. The rust is pushing them away from the drive shaft. This has got to have an effect on the balance, though I haven't noticed it yet. Should I be worried?
