I have a 8 3/4" cone posi. rear axle that is making noise, so I pulled it out to find out what is going on. I used the 80W90 oil with the Mopar additive.
That is not my question, I have a question on what oil to use and what additive to use if any.
I am using Valvoline's 80W90 oil. Do I use a additive? If so which one? the Mopar or Ford.
If so, I have a bottle of the Mopar, but what is the Ford's part number.
The internet is great but sometimes it creates more question that answers.
