Ok guys. The rear pinion seal went out on one of my e350s. After pulling the seal there are no part numbers on it. Its not the typical ujoint style yoke. Its the converted round plate. After pulling the tag and going to ford and five other parts houses, i am yet to be able to find the correct seal. We tried one that was close but after we drove it again this morning it started leaking again. I know the manufacturer is national because of the nak on the gasket. There is also a letter number combo and then the diminsions of the seal. I have emailed them but no support really cause its in taiwan. The rear end is from 94 and its a dana 60 29 spline. 9.75 gears. There are no crush plates and the pinion nut is torqued to 150 lbs. Any ideas??
