Small, dry bar of soap ... very lightly rub (using pliers to hold it so your hand in not in the belt area) onto the belts one at a time at idle while they are squealing ... if it stops, its a belt. if it has no effect, it is a bearing.

Belts squeal when dirt gets into the grooves of the pulleys.. or if they get polished smooth from sand, etc. ... removing belts and scuffing them up + cleaning groves with an old wire brush can solve a lot of it. Pulleys are also not supposed to be shiny.
