Below is a pic of my Dana 35 rear end and custom cover, (not sure what brand or who put it on, some PO). I believe the top hole is the fill hole. I believe the lower Allen bolt is the "full" or inspection hole. However when I take that bolt out, lub comes out like crazy. I worry that means it is over filled. I am having some noise coming from the rear end and I do not know what the damage or harm is for an overfilled Dana 35 pumpkin. Can any one help with info.
