I need to replace front driveshaft. Repairing mine is not an option. A piece is chipped off the yoke, unfortunately it wasn't on the yoke flange which would have been much simpler a repair.
I bought a used driveshaft from a salvage yard. It's off a newer model then mine and from all the info have read and by physically laying them side by side they are almost identical. Only difference I can see are what I believe are the balancing weights (1x1 in squares) are welded on the driveshaft I bought, unlike on the one from my truck just has somewhat smaller and round what I'm guessing are weights.
Lastly I plan to replace both U joints before I install it.
So my first question is, should I have the driveshaft professionally balanced before installing?
My second question is, do I risk any damage to either the xfer case or front differential by not having it balanced before I install it?
Thank you in advance for any answers, advice or recommendation's.

Welcome to 2CarPros.
The weights on the shaft are for balance. That won't change unless one or more is removed or the shaft is altered by changing the yokes or cutting/welding on it. Then you would need to get it re-balanced. As it is you will be fine. Just be careful replacing the U-Joints, very easy to bend an ear or set the caps wrong.
That said, how large is the chip and where is it? Could you take a picture of it and post it here. Unless it is a large chip that is near one of the caps it may not be anything to really worry about.
