just went to lkq and found a 4 banger comanche do they have 4:10 gears like the 4 banger cherokee's

 

You need to verify with the tag on diff cover or actually check the ring & pinion. It'll be either 3:73, 4:10 or 4:56.

 

4.10 is most common, but like the guy above said you need to check.

If you can get it in the air you can simply turn the wheel or hub while counting how many times the driveshaft turns per turn of the wheel. ~3.75 turns is 3.77, ~4 turns is 4.10, ect.

 

Thanks i will be going back there tomorrow to pull the cover and see
