ive been using the search function, but i didnt type in gear code, i typed in axle ratio.
but thanks for your help

I'm not sure about your door sticker or Brian's site, but my understanding for years now has been that all manual T100's came from the factory with 4.10's and all automatic T100's came with 4.30's.

Ask around on some more active T100 forums and I think you'll hear the same from other longtime owners....

I think the 4 cylinder manual transmission 1994-1998 longbed T-100s came with a lower gear than 4.10...at least that's what www.car-part.com sez.

I'd verify the gear ratio by ErikB's guide...

im so confused i dont know which chart to use
one says 3.36 and the other says 3.58???

What's my gear ratio? There are several ways figure it out: (top)

* If you think your axle gearing has not been changed since it left the factory, you can read and decode the "axle code" from your vehicle information plate. Off-road.com has some pretty good information how to do this HERE (scroll down to the section titled "Gearing").
* If your differential has been removed so that you can see and count the teeth on the gears, you can divide the number of teeth on the ring gear by the number of teeth on the pinion gear to come up with their ratio. For example, 41/10 gives you a 4.10:1 gear ratio (the most common stock ratio).
* To verify gear ratios w/ the diffs on the vehicle, there is the "spin and count" method:

For "open" diffs:
o Block the tires at one end of the vehicle to keep it from rolling, and then jack up a tire on the other end.
o Place the transmission in neutral and release the parking brake if you are checking the rear diff.
o Spin the tire exactly TWO full revolutions while at the same time counting exactly how many revolutions the driveshaft spins (marking the driveshaft and tires beforehand will make it easier to count revolutions).
o The number of revolutions the driveshaft spins is your gear ratio.
If it spins just over 4 times, then the ratio is probably 4.10; 4-1/3 = 4.30; 4-1/2 = 4.56; just under 5 = 4.88; 5-1/3 = 5.29, etc.
