This is going to sound pretty stupid, but where do I find my gear ratio on my 2002 F-150 S/Crew FX4. Recently bought it and am curious what it is. I did not see it on the door sticker. Anyway, if anyone can help me out after you quit laughing.

There should be a code on the door jam sticker. Look under axle on the sticker. Probably H9 = 3.55LS. There is also a tag on the rearend under one of the cover bolts. The bottom line of the tag next to the nut will have the ratio. 3 55 is a 3.55 open rearend and 3L55 would be a limited slip 3.55.
You have a 8.8 differential in the front and a 9.75 diff. in the rear.

 

Lxman1,

Thanks for the info. I was looking kinda funny standing in my driveway scratching my head.

 

Well, as long as you weren't rubbing your belly at the same time
