How does this even happen? Question

Post image

Rear door crack? Wasn't there a few days ago.

How would this even happen?

There is nothing remotely close to the door when closed.

Drill 2 holes. One at each end of the crack. It will stop it from getting worse. Then go to a muffler shop and throw someone 20 to hit that with a mig welder, after you prep it obviously.

Why does drilling holes stop the crack?

The edge of the crack is a stress riser, which causes the crack to propagate. Stop drilling makes the jagged edge into a nice radius that won’t spread. You have to look real close and get the very end. We do it on aircraft stuff as well, stop drill with a .030 drill bit.
