I finally got a copy of a Ford manual. In it, it gives three different 4:10 ratio rear axles, with 6250, 7400, and 8250 max trailer ratings. What is the difference between these three axles? It isn't anything like being limited slip either. The limited slip codes are c5, d5, and F5. I thought that maybe it had something to do with SRW vs DRW, but that isn't it either. So, what's the difference? BTW, 1992 F350 ZF5 SRW Crewcab. Thanks.
