The ratio is on a tag on front and rear axle between 2 of the cover bolts
What size axle does a 99 wrangler sport have
3.07 or 3.73 to 1. Could be either.
if it is a 4 cylinder 5 speed probably 4.10 ratio.that what mine had in it but changed to 4.88
In order to determine what axle and axle gears you have there will be a metal tag that is stamped with the gear ratio on the cover bolts and Dana has a number raised on the right bottom side where the axle tube enters the pumpkin. Between the two it will tell you what axle and ratio you have. If you have a limited slip then you axle ratio would read 3L55 instead of 3 55

The only factory front axle that came in a 2001 Jeep Wrangler is a D30.
I have a 95 and the gear is 4.11. It is on a little placard on the axle diff. cover. Can be either on the front or rear. Good luck.
Dana 35 or Dana 44
A stock 2015 Jeep Wrangler is equipped with either a Dana 30 front axle or a Dana 44 rear axle, depending on the specific model and trim level. The Dana 30 front axle typically features a 3.21 or 3.73 gear ratio, while the rear Dana 44 can have similar gear ratios. These axles are designed to provide a balance between off-road capability and on-road performance.
