No there's no oil filter on it that's involved the differentials

There is a 3/8 square plug the is removeable with a rachet. Located on the passenger side of the rear differential. This is where you refill it.

You got a refill and drain plug-drain it and replenish it and see what happens

Alright, Where can I find a gasket for a Z71? I'm not finding anything really.
