Getting ready to change the rear diff fluid and discovered I do NOT have a fill hole/plug!  The only plug on the rear diff is a plug on the differential cover.  If that is where to drain the fluid, where do you fill it?
 
You have to remove the cover or take out the plug and siphon as much as you can out.
I would remove it and clean it up.
 
Thanks for the reply!  I removed the cover and plug and just refilled the diff until the oil started to seep out of the plug hole and screwed it back on.  (put a new gasket on as well!  Thanks!!
 
I run mobile 75w-90 synthetic.
I have limited slip G80 locker.
No chatter or slip
