My van is waiting at the shop, front diff and axles disassembled, waiting for the correct inner axle seals to be found. The p/n on the parts list from SMB indicates a Ford part number, but the seals were wrong. Getting them from Ford for an F-350 front end were wrong. Dynatrac/Spicer has not returned calls probably because of the virus, but they built the unit. Anyone know what the correct seals are for my front axle? Gotta get that thing out of the shop!
Try Currie Enterprises in Orange or Corona Calif. They'll probably have them in stock! They build axles with all sizes of inner axles available.
