My rear axle code is 37 what is it? Can't seem to find a list of codes for my 2012 f250. Will need to identify my front axle also but haven't looked at the axle yet.

 

top of this page... under "Tools" is Vin decode.

enter vin.. will tell you what your truck was built with.

Gas had 3:73 and 4:30 and 4:30 is very rare.
Diesel had 3:55. and I do not remember the second one.

 

Using the app I don't see a tools option. I've tried pulling up the window sticker using the vin on various web sites with no luck. just looked at the tools on the computer and it pulled it up. I know i have the 3.73 gears but im looking to see if i have the limted slip or open diff in the rear.

 

If you don't have the elocker it's open unless it's a dually as those were the only trucks offered with limited slip since the elocker came out unless I'm missing something. You can enter your vin here for your as built info.
