Propeller shaft balance

[reses]

I got all the parts for the AWD conversion but in my propeller shaft the last section (or first, the one that connects to the transfer case) got the last u-joint shot, there is no movement in one direction, I was thinking of swapping that section with a good one that I found from another part out (same 5 spd one), but my question (sorry if its too dumb), can be made, those are balanced as a whole or by sections? (I don't want to put that part and unbalance the driveshaft)

it sometimes works, sometimes vibrates.

Call the drive line shop you would have do it.

I replaced the front section on my 5 gear, didn't add any vibes- just make sure you get it clocked properly with the opposite end.
I think the rear 2 sections would be more critical to be balanced together, due to the lobro. If you end up with slight vibes, you could always try turning it 180* to the rest of the shaft.
