Or if you change ujoints and don't mark the yoke (you can put it on 180* out) you should re-ballance.
........ changing just the ujoints WILL change the ballance of a shaft. Especially if using a precision or house brand ujoint. Once you shim all of the endplay out of the joint and set the keepers properly the joint won't be centered in the yoke or at least not in the exact same spot as the ujoint that was in the shaft when it was ballanced.

If you paint/get undercoating on your driveshaft it can upset the ballance of the driveshaft.

pretty much any time you modify a driveshaft it needs to be reballanced.
