I dont have any paperwork that tells me this i need this info for custome worksheets for troyer.Where can i find this?Any help is appreciated!

 

Look at the label in the drivers door jam area.
Your axle indicator will be found on the Certification Label
bottom line in the middle labeled AXLE.
Wright in the code you see right under this. He should be able to tell from this what ratio the truck has.

 

Last 2 F-150's I've owned also besides the door sticker there was a metal tab on one of the diff. bolts that had the ratio stamped into it.

On the driver side door pillar down near the bottom on the white tag you’ll find the axle ratio code
