Think of like a washing machine. The barrel spins freely when unloaded. When loaded, all the clothes dissipate evenly and keep the barrel spinning on an even path. If something becomes lodged though and shifts all the clothes to one side, the barrel begins to rotate off axis, thus making noise. even if you put the washing machine on an uneven surface, the barrel finds a way to center itself when loaded.
