generaly a bearing will whine on power and coast, while the gear set can be just one or the other.
could have caused damage on the initial failure.
the mufflers are on either side of the pinion yoke on your car, aren't they? if so, that can contribute to some of the heat.
i have installed gear sets that were noisy, sure that some thing was wrong, i opened them back up, took a tooth pattern and back lash, had my boss double check. they left that way, and the customer is happy.
i would recomend a doubble check of tooth pattern and backlash, maybe a test drive at your local drive line shop, or a second opinion from someone you trust..
then run them untill you have time, money, or need to replace them.
i personaly would be concerned as to their structurial integrity after their first failure.
maybe not wasted, could just be paying for education. we all have done that!
