i have a 2003 x model tj, and this maybe a stupid question, im pretty sure i have 3.07 gears. my question is, the gearing is the same front and rear correct? i am looking to buy new gears and want to make sure i need the same for the front and rear. also, how hard is it to change gears?

Yes the front and rear are the same. I havent actually changed gears, but the process and reviews of people whose opinions I trust have me wondering if I should just bite the bullet and let a pro do it.

Since you have an auto, you should have 3.73 gears.

Your current gear ratio is important to know so you know what parts are required when buying new gears.

If you have 3.73, you do not need new carriers to regear to a lower axle ratio such as 4.56 or 4.88.

If you somehow have 3.07, you'll need new carriers for both front and rear axles.

It's a little involved. You dont just bolt them in and go. They have to be "set up" properly or they will burn up in 100 miles or less.

Find some body you know that knows what they're donig to walk you thru it the first time. the education is absolutely priceless. There is also a small investment of some tools you will need to do the gear swap. Those of us who have done it also had to do it the first time. It's not real hard, just a little time consuming.

Good Luck
