Yes, balancing can make it worse or better. If the heavy spot of the tire and the drum were opposite each other, balancing will make it worse. If you never checked your drums for balance, you have no idea and shouldn't jump to conclusions.
That depends..
The drum has a much smaller diameter AND MASS than the tire.
Car drums and rotors ARE "balanced", pretty easy to check to see if the drums have been balanced. Typically balancing on drums consists of the manufacturer either drilling /counter sinking into the heavy spot or adding a permanent weight (spot weld) to the light side.
Balancing drums on a trailer is not going to DRAMATICALLY change anything with the trailer due to the small diameter and MAS of the drum,
Balancing the tire on the other hand may or may not make any noticeable change since you are not RIDING in the trailer.
I have run trailer tires balanced AND unbalanced and FOUND NO DIFFERENCE in how the trailer tows or feels. How ever with that said, balancing CAN potentially add some life to the trailer tires since it will REDUCE the BOUNCING of the tires if they are far out of balance.
