^^^I use this up in the JK section, but it would also be applicable, to this TJ section. I hope that it helps....

I have a stock Rubicon that comes with 4.10 gears and 31ish tires and it moves fine. I'd try your current ratio before spending the money on a regear.

flyinhawaiian Hey distortedtj
Since were on the topic of Diff. I have a 97 Wrangler 2.5L 4 Cyl. And i have plans to put a 2" Sus. lift and a 1.25" BL with a 1'MML just to be safe.

Cause I want to fit some 32" in there and with my TJ being a 97 with the stock dana35 with 4.11 ratio. will the stock gear ratio make them move or would it be better to put in a 3.73 ratio or something else?

But can you imagine what happens when you try to drive on a solid, good traction road surface? Your vehicle will jump as you try to turn one way or another. There are a lot of different kinds of lockers, and some are "true" lockers and some are not.

I don't know enough to tell you what is best or how many there are.

I'm no expert on the matter, but from what research I've done on lockers... when you DONT have lockers installed, if a wheel comes off the ground, the wheel can spin and the other wheel can sit still. a wheel in motion is less resistance, thus building less torque from the engine. (Thats why using your brakes/throttle simultaneously and carefully when stuck sometimes works if your stock diff isn't cooperating) The torque sent from the engine to each wheel is 50:50, always. When a wheel spins the engine doesnt build torque. the other wheel alone although building torque, isnt always enough to get moving.
However when you have Lockers installed, it MECHANICALLY locks the two wheels into a stiff axle, one wheel cannot move without the other. therefore it doesnt matter if you have one wheel up or not, you build alot more torque.. but just like jp2611 said, it gets squirrelly when you have to drive on dry ground, pavement, or even when your trying to drive on snow or ice effectively...
at least thats how it was explained to me.

rocket4x4 thanks for the info. i was just about to post about what axles i may have til i saw this.

The Fireman Very helpful and informative. Thanks!

Jerry Bransford All factory TJ Dana 44 axle shafts are 30 spline. The standard Dana 35c axle shafts are 27 spline, and the front Dana 30 axle shafts are also 27 spline.

StPaul74 This info in this thread has been pretty helpful for me. The guy at the auto parts store told me I had to call the local Jeep dealership to do a VIN search to find out what type of axle I had on mine. Thanks to the photos posted on here, I didn't have to do that. HOWEVER, the next question he asked was how many splines does mine have?! It's a Dana 44 on a 2002 Wrangler TJ Sport. Can anyone answer this for me? I have to replace the passenger side because the old one will no longer seal due to wear which is causing me issues getting my brakes replaced due to leaking fluids. Any guidance would be very appreciated.

Your's being a 04 sport ...It is stock with a D30 front axle and the rear can be either a D35 or D44.
Thanks I just wanted to have the pics-so that I could compare the next time I am under the Jeep. I have had 2 different shops tell me 2 different things and neither was a Jeep shop. By having the pics I will be able to know which I have-thank you. I 'scribed so that I can save the thread to my email/computer and will be easier to "pull up".

Have a good one.

The pics that have been posted also fuel this theory, but I'm unable to be sure, mostly because I'm a pain and am overly undecided.

Was anyone smart enough to cast any numbers on the diff to indentify exactly what it is and what year it was produced?

I wouldn't be such a pain but I've got a modded truck with a "D44" but I have no idea how to be sure or what generation the D44 is.

Well If it's the stock axle it is an 87 ...yes they did have a D44 option for the XJ from 1987 – 1990 : Dana 44, non-abs, 30-spline axleshafts with the "towing" package.

What was changed was the gears in your axle then it's just a regular old' jeep D44 with new gears. The only cast number on the axle will but just left of the diff cover on the center section under the tube....what the numbers mean...you got me there...but they mite lead you somewhere bud.

Would have to say that it all depends. If you are lookin for a mall crawler then I'd stay stock and save your $. If you are lookin to rock race then you'd want a D60/14bolt (or stronger). My guess is you are somewhere in between

Hate to answer a question with a question, but what are you planning on doing with the rig?

I had a detroit in my last 14 bolt. I rarely knew it was back there. I like having the option. So I'm not holding back this time.
