gearing

I just bought an 07 Wrangler JKU. How can I determine what the gear ratio is? There has been some work on the rig prior to me owning it and I want to know if anything in the gearing has changed since stock.

Thanks for the help.

Easiest way to know for sure is to lift both rear tires off the ground and put the axle on jack stands. With it properly secured (blocks on the front tires) get underneath. Turn the driveshaft and make sure both tires are turning the same direction at the same speed.

Mark one of the tires. Turn the driveshaft, counting how many times you have to turn it to get the tires to make one complete rotation.

3-1/4 => 3.21
3-3/4 => 3.73
Just over 4 => 4.10
4-1/2 => 4.56
Almost 5 => 4.88
Just over 5 => 5.13

All the rotation counts are approximate.
