Welded diff help

[zooopreme]

And people really ask why Florida is at the end of almost every joke in Zilvia.

Start using your damn head and retrace your steps and rule everything off.

The only thing that you messed with was the diff. You didn't take it apart from the housing. Your welds sucked and aren't clean. You mixed oil. You haven't opened the cover up to inspect everything.

If you want my honest opinion, nobody is going to be able to answer your question because they probably did their shit correctly: welding it cleanly, not mixing gear oil, etc.
