I know it's metal, I'm just not entirely sure what could have gone wrong with the reassembly to make something destruct itself.
For some reason my fill plug is not picking up any shavings. I have a Solid cover and I can't remember if it came with this plug or if I reused the factory one.
The next day that it's not freezing out I'll have to pull the cover and see what's going on. I was told it's my carrier bearings, but I can't imagine why everything was fine until the seals were replaced. I understand the process of replacing them, and I know that the entire gear setup has to be removed from the housing. I thought it was pretty fool proof.
