The alternator on my car is beginning to whir & whine a bit. What is the best option ? - I can buy a brand new one - costs £££s; or, I can get a 'refurbed' one from online. I can send it away to get it re-built . . . . . . . surprisingly, this is about half the price of getting one which has been 'refurbed'. Has anyone ever repaired one ? I suspect that what is required, is a set of new bearings and I'm tempted to have a go myself, when I've some spare time over Christmas - anyone fixed an alternator ? Which option, might be your choice and why ?
