i have 4:10's
went to the stealership and had them pull the vin
thanks guys

i bought a used 07 unlimited, standard tranny, 4x4, and i would really like to know what gears i have in it. Is there any way to find this out? The sticker on the axel is worn.
thanks

if it has the trail rated badge on the side you have the 3.73's. thats pretty much standard. the only other thing i can tell you is to call the dealer and give them your vin number. they can tell you that way.

Plug your VIN in here to the Jeep site and it should tell you

If you want to know for sure, and remove all doubt, do this:

Chock the front tires, fore and aft.
Put the transmission in neutral.
Emergency brake off.
Jack the left rear tire off the ground.
Put a jack stand under the frame, just in case the jack fails (had to add this).
Put an index mark on the aft end of the drive shaft, visible from the left rear wheel.
Put an index mark on the left rear tire at the 6 o'clock position.
Rotate the left rear tire 2 complete revolutions while counting how many times the index mark on the drive shaft passes its original position.
That number will be your axle ratio.
Remove jackstand and lower jack.
Put transmission in gear and/or apply emergency brake.
Remove chocks.
If you have limited slip, jack up both rear wheels and rotate one revolution, making sure both tires rotate equally.

If the driveshaft rotated almost 3 1/4 turns, you have 3.21
If the driveshaft rotated almost 3 3/4 turns, you have 3.73
If the driveshaft rotated a little over 4 turns, you have 4.10

I have a wrangler x with s package (2008). It has a trail rated badge (don't all wranglers?)

the window sticker says:


3.21 Axle Ratio
Next Generation Dana 44 Heavy Duty Rear Axle
Next Generation Dana 30 Solid Front Axle

Which now disappoints me...

Nope.
3.73's didn't exist in the '07 model year. Either 4.10s or 3.21s

BlackNorthernJK

More info dude. Sahara, X, Rubicon ?? Tow package or not?
Ronjenx has the definitive answer for sure.
So you know. Typically the Standard X without tow package was the only one that came with 3.21's....pretty much everything else had 4.10's that year

Excuse the dumb-@ss question but what's in the tow group? I thought it was just gearing but on the site it says:

With 3.73 Axle Ratio You Can Tow 1000 lbs
With 3.73 Axle Ratio and Trailer Tow Group You Can Tow 3500 lbs
