"Not having any problems" is all relative. If you drove a Jeep properly geared for that size tire, I think you'd probably no longer be happy with your current gearing.

Yep you were right, the tag was bent so it was tough to see the 3. Is 3.07 too low to run 33s?

Don't be surprised if it says 3.74 or 3.08 instead of 3.73 or 3.07, the TJ's front and rear axle ratios are .01 apart.

And with an open axle when both tires are off the ground, you have to rotate the tire twice to cause the pinion shaft to rotate the driveshaft a number of revolutions to equal the axle ratio. Be sure the transfer case has been shifted into Neutral before attempting this.
The tag on my rear axel reads 2111760AB on the first row, and 07 5993-1 on the second row. Any ideas what that could mean? I know it's not the factory axel, it was swapped out of another wrangler by the PO

Thanks I'll try that tomorrow. I didn't know the wheel had to be turned twice, I thought only once

Wheres the pinion?

MR.CLIFFORD Spin the tire one complete revolution. Count how many times the pinion rotates. ~3.5 turns = 3.55s. A little less than 4 turns = 3.73s. Over 4 turns = 4.10 and so on and so on.

02Prove Look on the diff cover... should be a stamped plate on there somewhere.
