This car has 102,000 miles and the original factory alternator went out a month ago. I had it replaced with a re-manufactured alternator which lasted 2 weeks and then it went out. I replaced this one with another re-man and it lasted a week before the bearings melted. I have the 3rd re-manufactured alternator on it now and the bearings are squealing and the unit is getting very hot. Can someone tell me what maybe causing this. I can't imagine I have gotten 3 bad parts in a row. Please help. Thanks in advance.
