Those of you that perform this yourself, is there a pump available that could suck most of the old fluid out through the hole? I know of the pump that can pump fluid in. I'm trying to avoid pulling the diff cover off as you can probably tell.

I had valvoline do the fluid change the last time & I believe they just use the hole.

Yeah there's a pump that suckks it out, but take cover s off so you can check gears and such.
