What is the easiest way to tell what gear ratio you have, short of jacking the truck up and spinning the driveshaft ????

 

Just check the axle code on the sticker

Expy
19-3.55 non-limited slip
17-3.31 non-limited slip
H9-3.55 limited slip
H7-3.31 limited slip
H6-3.73 limited slip

Additional Others
19 — 3.55 non-limited slip (Econoline, F-150)
18 — 3.08 non-limited slip (F-150)
17 — 3.31 non-limited slip (Econoline)
H9 — 3.55 limited slip (F-150, F-250)

With the exhaustive list above, I don't know how several Expy only codes are missing but they are. Here are the Expy axle codes:

19-3.55 non-limited slip
17-3.31 non-limited slip
H9-3.55 limited slip
H7-3.31 limited slip
H6-3.73 limited slip

 

Thanks Buzzard...

 

My sticker says 935E-1....How do I read that?

 

sounds like wrong!? I have never seen an axle code like that.

 

It's on the sticker attached to axle, and on the stamped tag on the carrier housing. I took pics of it if you wanna look at them.

 

The Axle tag and sticker will have a series of numbers. You'll need to post all of them to get the correct answer. THe codes the guys are posting are found on the driver's side door, in the outer edge.
There is a sticker there that will have a 2 element (could be numberic or alpha-numberic) above the 'axle' section.
