Holy mackerel, I don't recall the last time I had an alternator rebuilt. I think 25-30 years ago. For these trucks they're cheaper to buy than to rebuild and then you just exchange them if they are bad. But that's my opinion.

It seems like you still have something wrong with the alternator. If it's getting hot and tightening up on you enought to want to slip the belt, I would say the rotor or bearing is causing this. I just can't see where the regulator would cause a bind in your alternator.

See if they can find the problem. But, the new regulators and rebuilt auto parts alternators are not very expensive. I'd keep the old regulator if it's working though, just because it's original...
