Yesterday (6/17/2023) I installed a front differential pinion seal. (Mileage 147,643)
This had been leaking for quite some time, and I had topped off the fluid once to keep it from self destructing .
I used this factory pinion seal installer and it worked flawlessly. I obtained this tool when I put 4.88 gears in my supercharged 98 Explorer.
Ford's service manuals have a list of tools used to do certain things at the top of the procedures, so I search those tool numbers and find them on Ebay and other online places.
New seal installed, I did clean the front differential with brake clean after this picture was taken.
