Rear End Numbers and Ratio
I am in the middle of servicing the rear diff. on my 64 1/2 ton GMC. It has a tag on it that say "46-13" on the top and "3.54". Now i'm thinking 3.54 gears....What is this thing and whats it doing under my truck?
It has patent #'s on it twice and the only other # was C90294 at the top right rear and 44-1 at the right bottom rear. Its a 3 rib on the driver side and 1 rib on the passeger side of the carrier. Any idea what I'm looking at without seeing a pic?
