I had to drill a couple of holes in my carrier to remove the broken retaining bolt. Someone told me that this may ruin the carrier because it is not as strong where the pin (bolt) goes into the pinion shaft. Is this true? there are only two small holes on either side of the pinion shaft. I am using as a daily driver, so it will not recieve any hard wear and tear. I would rather not replace the carrier, but I dont want to reinstall a faulty carrier either.
