76 dart 225

So driving home it felt like a flat tire. Pull over and drum was smoking. Thinking maybe it was to tight. So I let it cool down a bit. Hit 20-25 mph and it starts up again. Pull over at a school go-to remove drum and I feel like the outer bolt is stripped. Looked at the bearing notice it's blown out. Go-to AutoZone pick up some new bearing to replace again. I just replaced em a few months ago.
Sure enough I get the bolt off and it's stripped. To top it off drum won't come off. Outer bearing froze on.
Junk yard said they would wait for me 45 min after they close for me. Hopefully they do.
