Reply to "Bump and leak from zf rear case"

No safety wiring of ring gear bolts.
Bolt comes loose, the bolt head shears off, and damages ZF case and or internals.

Do not drive pull trans and remove bottom cover to inspect before damage is done. The pencil hole and crack can be welded.

The hole is not in the area you haved pictured is it? Broken bolts usually damage the bottom cover of the ZF with the two cross bolts
