i just took a look at the rear axle code on my 86 bronco and wanted to see if someone can tell me what it reads i know it has a 9" rear but i really cant figure out what the ratio is or what the 6E stands for so here is what i got from it thanks for the help!! S31 50 9 6E
well i just double checked the numbers on the rear and they are S31 50 9 6E thats weird because ive done research on here and i see alot of ones with the ones you have listed. im just wondering if the rear might of been swapped out for some other one but i dont know what other ones would have them numbers.
Sorry about this, I go in and out of the 73-79 truck forum and bronco forum, and I thought I was in the truck forum.
Every Bronco I've seen has come with 3.50 gears(78 79), and 3.54 and 3.55 gears(80-96).
