So #1 and #2 mains. Any significance to that? Do the front ones fail first?

If mains were failing routinely before rods, I'd be more worried but this situation seems relatively rare so far. Maybe that will change now that the cars are 5-10 years old and miles are going up. Still, though, makes me want to do the mains as preventative maintenance. It's just a massive preventative maintenance project -- bigger than just changing the motor if it breaks but of course you would want to address bearings on the new used motor so it's about the same. Cheaper though if you can DIY the preventative maintenance bearing change.
