How TO Find Gear Ratio Of A Non-Posi Ring & Pinion

How to figure out your gear ratio on most cars without taking the diff cover off. We have an underpowered jeep with big tires, this needs a gear change or an engine change to overcome the larger tires that reduce our running gear ratio. Our truck with a v8 is more forgiving to changes in tire size the 2.5-liter engine in this jeep, but we have to know our current ration before we can make an educated decision on gears we need to change to. This jeep had a dana 30 and dana 35 axles so when we do change the running gear the lowest we can go is down to a 4.88. With the tire size on the jeep a 4:88 gear should give the jeep the same power it had with factory tires and a 55 MPH it should run the engine at 2300 RPM. I did have a turbo Miata with a 4.88 gearing with much smaller tires and the RPM for that car at 55 was over 3000. Would not want to run the 2.5L in the YJ Jeep at that RPM all the time but with the larger tires, it would be a 6.50 gearing. We have more videos to come for this YJ Jeep Wrangler that we include DIY exhaust and gear changes. You can also see other videos for this jeep and other projects we have done and are currently working on.
