Depends on the engine in the YJ.

Re: Axle ratio

Could be 3.07, 3.55 or 3.73, or anything else if modifications have been made.

Ways to find out:
1) look on the tag on the axles
2) jack up a wheel, mark the wheel and the drive shaft, put it in neutral, turn the wheel and count the revolutions of the drive shaft in relation to the revolutions of the wheel.
3) remove the diff cover and count the gears in the ring and pinion.

Re: Axle ratio

Daughters 90 YJ, 258 Auto 3.07's
Son's 88 Sahara, 258 Auto 3.55's
From what I've seen these are the 2 most frequently used ratios for 6 cyl., auto, YJs
Check the axle tags, Dana always puts ratio tags on their axles. There might only be 2 numbers, like 49 and 18, the large number are the ring gears, and the small number is the pinion, just divide the ring by the pinion for the ratio.
