did he drain fluid again and fill correct ? what leaks you video picture ?

Customer: replied 11 months ago.
When it first leaked we checked the fill bolt and some dripped out. But it continues to leak a few ounces after driving

Just trying to figure out what could be causing this. Mechanic installed the used final drive and replaced a filter but he can't say why it's leaking - or venting. Is there something wrong with the used part? It seems to run ok

​it should not leak i cant say if he did anything wrong on install but there is not much you can do wrong if is leaking i think is bad used part i seen it in past
