the problem with this site is that 90% of the people on here are keyboard mechanics who aren't capable of replacing the starter anyway. But they sit around all day reading things on the net, & "if you read it on the internet, it must be true" so they post what they read, NOT real world experience.
don't believe me? search for the dozens of threads discussing wiper blades & headlight bulbs, oil weights, etc.
Back on topic......whenever I've had an electrical part (starter, alternator) go bad, I've always gone to my local rebuild shop & had them rebuild my part. I always ask for the bosch or other top internal parts & have never had a problem......I don't think I've ever paid more than $100 for a rebuild....Pat
