Gear Ratio Question
hey yall, I was just wondering if there was any way to know what my rear end gear ratio is without jackin the truck up and doin the ol' "turn the driveshaft and watch the wheel turn" trick. Any help on this would be much appriciated. By the way, its a '94 F-150 4x4 with the 4.9L and a 5 speed manual trans. Thanks much.

But is the rear diff. factory? Over the years people change them out,thats why I said check the diff. it's self. Although if it is stock the door sticker is a great place for the info instead of crawling on the ground.
Just thought I'd throw that out.

oh, I'm puttin 33" tires on it, and 3.73s are the best gears to allow for good gas mileage (Researched Fact). I drive 120 highway miles a day, 4 days a week, but on the weekends we all go muddin and stuff, so I need some versatility. my MPG is in the 20-24 range now. I have researched it extensively, and done some figures, and 3.73s are gonna give me CLOSE (+-2 mpg) to the same mileage.
