So the other day i changed my rear dif fluid in my 1995 with the 7.5, i used 80w90 gear oil and now its making a whining noise. I didnt not have that noise before i changed it and i rechecked if i had enough fluid and oil came out the fill plug like it should. i dont understand why this is, could it be because i used the house brand gear oil? Any help would be great thanks!
