Effects of dual-pinion drive in spectrum of a ball mill

Ball mill drive system. We measured the vibrations on both sides having a huge spike on the gearmesh frequency (and it's harmonics) as the pinion of one side is at fault (and going to be replaced in a month), but we have an spike on half of the gearmesh frequency, could it come from the fact that it is dual driven?
