I think the columbias had a D44 in the rear, so I'm guessing 3.73's

Does anyone know where i could find a resource to determine what gears I have 2004 jeep wrangler X columbia edition.

Dealer should be able to give you a printout with your vin number. Might also be marked on the ends of the axles with tape or the old tried and true method, pull the cover, count and do the math

You'll find the ratio embossed into a steel tag bolted between two of the differential cover bolts at the 9 o'clock position.

If your rear axle is a Dana 44 as identified by its stop-sign (non-oval) shape and that it has a threaded steel bolt plugging its lube fill hole, it has a 3.73. All non-Rubicon Dana 44 axles on the TJ come with 3.73.

If it's a Dana 35c as evidenced by its oval shaped differential cover and plastic snap-in lube fill cover, it either has 3.07 or 3.73 gearing.
