Determine gear ratio from PN on ring gear?
While I was flushing the fluid in my front diff, I believe I have the stock 3.73 gears still but was trying to confirm. I wrote this number down off the ring gear:
10 02 04 Dana T47918F8L806 41 11
Then a little further away is printed 3 99.
Is there any place that can decode the part number or cross reference it to a gear ratio? I think the fact that it says Dana and is such a long part number means that its the original gear set, because I think most aftermarket rings are stamped with the ratio?
