Default Drive Shaft knowledge please..

Anyone had there drive shaft balanced? My vibration is back again when I'm under heavy load and I'm hoping this might be the reason.
What are the signs of a drive shaft being out of balance?
I have replaced the flex disc, csb,and trans and diff fluids recently so those are out as far as poss culprits.
There Isn't much left to fix in the drive train so this is next.
Thanks in advance

I have a set of E46 motor mounts.

They're for sale if you want them.

vibration from the driveshaft could be at certain speed too(but the vibration will be more severe at some speeds due to how unbalanced it is), when you took the driveshaft apart for csb did you mark it properly? there is only one way that i know of to fix it, replace it. should be pretty cheap thru cls, bmf, etk.

However can you elabarate on when and what speed exatcly you feel the vibration? also how bad is it? when the driveshaft is out of balance the vibration is rather severe. there are dozens of things that could give viration under a load

and Jeremy did you buy a new Stang???

VS did it so......
Its not a really a speed thing, its when i'm below
4k rpm and I give it a good amount of peddle I feel it coming from my rear floorboard area, its like rolling over a small rumble strip.
