A locker is just fine in a d30... better question is why? Seems to me it's an axle folks want to upgrade eventually, so why throw money at it if you don't have to. The 513s... the ring gear is getting pretty thin, I'd not go there.

A locker is also just fine up front. But, being in the snow... one that can be turned off is what you want. Since we don't have manual hubs, a full time locker will make it more difficult to drive in the snow. Point here is... you live in the snow, a front locker won't be used much.... but, when you're in a jam, it sure might help you out of it.

A locker is a much superior device to it's limited slip brethren. Perfect example for you is this example... your Ford pulls hard while your Jeep spins and spins. The Ford has a locker in the back, the Jeep only a LSD. (assuming a late model Ford with the e-locker option)

When your Jeep detects slipping, it applies the brakes in certain areas to try and correct any sliding and stabilize the Jeep. Thats why you will slow down, because the computer is throwing power all over the place (you can sometimes see the headlights dim when the ESP engages).

If you turn ESP off it won't really help when in 4Hi, but 4Lo will give you less ESP features and not kill the power when there is slipping. If you end up in another deep snow situation, I would try throwing the Jeep into 4Lo and 2nd gear to get your speed up enough to plow through. Worth a shot.

Your trucks probably have less strict ESP features because they don't have as high of a roll over risk..

Lockers with a lot of wheel spin will break your D30 gears (pinion gear) when they grab traction suddenly, so unless you're mindful of that you may end up replacing the front end gearing.


Also, did you get a good alignment after doing the lift and tires? if it's off the tires will grab and pull you all over the place in slippery situations.

If you're going to regear, x3 on the Eaton TrueTrac front and rear. Perhaps the Eaton E-Locker in the front, but that's a lot of cash.

I went through all of this last fall...

I ended up replacing the d30 with a Dynatrac pro rock d44 with an ARB locker and 5:13

You have a choice in the back, just add an ARB locker and 5:13 gearing, or just go all in, take out factor d44 and replace it with a Dynatrac d60 with ARB locker and 5:13 gearing

the new d44 and d60 are custom built for you, so you get to pick which axles you want and while your at it do it right, replace your front and rear driveshafts

about all that's left stock are your factory brakes, the outer axle and some bearings

you wind up with a hell of a Jeep that is much sturdier than a factory Rubicon

What? D60 for a mall crawler? I don't know man, seems like thats a bit more than his wife needs in a dd rig.

As far as tires on the jeep, im currently running trail grapplers. I havent played much with the 4wd system either as i dont drive it that much. My half ton i used to have engaged the rear and when applying lightly to the brake also. You also had to hold the 4x4 button for 5 seconds to completely disable the TCS, if not even in 4x4hi it woudl cut power to the wheels to keep from spinning, which i didnt really understand the purpose for...

So basically once i get used to this Jeep 4x4 I will be alright, BUT.........while im doing the gears may as well throw in a true trac in the rear
Unless you have lockers in your SuperDuty......No they don't. I have a Cummins 2500 and it goes great in snow. It's all about wheelbase and weight. I agree with the guy that said get to know your vehicle and how it behaves in snow. The jeep is much lighter and a much smaller wheelbase than a SuperDuty. Lockers won't help like you think they will. You still have a light, short wheelbase vehicle. Take your time and know your limitations.

Matthew isn't suggesting a d60 in the rear for you,,, just a d44 in front,, and like others have said,, lock up both ends. This will cure what you experienced, and make you 10x's more capable in the mud you partake in! !

I know i dont have lockers in my powerstroke. but in 4wd the traction control turns off. there is no braking or power loss done by the truck. Same as turning the traction control off in 2wd, once selected its 2 wheell peel. All im saying is I dont understand the reason for this traction control system while 4wd is engaged in my jeep. Thats all im interested in. Im being told its my enability to drive a jeep.......If my vehicle has to control power for me and help correct my steering....whose driving, you or the jeep.....I guess i was expecting to plow through the fresh powdered drifts, not to mention its colder then a polar bears sack and almost had to walk.

Thanks for the help everyone...going to continue doing some reading

Yah when we bought this i went into it blind....hence the sport we have now...Regardless if i ever use something i still want to have it when i need it. Sounds like to me if i already had my gears and had a locker up front today there would have been a good chance of me breaking something with the bigger gears up front.....bucking around and rockin the boat.
thanks

I like your thinking! Now i need some more cash!
Anyone have a 44 for the front they want to get rid of

While we are at it how about an extra LS3 laying around. 3.8L needs some steroids!
