Dana 30 locker

[purple xj]

I got a locker in a carrier all assembled and has a 4.56 gear bolt to it would i be able to just swap my 3.55 gear and install the whole carrier back into my axle instead of disassembling the whole locker to put it in my existing carrier?

[BermB1026]

did you get a matching pinon gear? if so...sorry but no, you'll also need to bearings, races, shims and well a professional install

As stated you need the pinion to match. You will also need to set up the new ring and pinion to properly fit in your D30. Biggest issue with the D30s is that the spacer shims are between the carrier bearings and the carrier. So you need to remove the old bearings (which usually destroys the bearings) and add the proper shims and press new bearings on. There not easy and you have to get it rite the first time or your going to go through bearings.

What kind of locker is it? A Detroit? Which type. If its a lunchbox style you just need to swap the center section. Or the where the spider gears are into your 3:55 carrier. If its not a lunchbox style you will need to reset the shims and do bearings. NOT cheap.

If its a lunchbox locker than $100 is a deal. But if its anything else its still a deal. But its gonna cost you. If you use the 4:56s you will have to match the rear. Just in the rear with the cost of a ring and pinion, install kit and install PLUS the larger carrier needed to use the 4:56s your looking at, at least $500 bucks. just for the rear. Then the cost of an install kit up front and the labor there.

What im going to do is the carrier with the locker in it right now has a 4.56 gear bolted to the carrier with the locker right now i want to take the 4.56 gear off of the carrier with the locker now and put my existing 3.55 gear onto the carrier with the locker in it i dont want to re gearing but is it possible to just take the 4.56 gear off of the locker carrier and put a 3.55 gear onto the locked carrier and it is detroit 27 spline racheting locker

If its a hole carrier change than no you can't. There is a change in the carrier size when you go up to 4.56 from 3.55.

Exactly. The carrier you have with the 4:56s is a larger carrier. The 3:55 carrier is a smaller design. If the locker is the actual carrier itself than you will need to use the 4:56s gears to use the locker. The carrier that has the 4:56s can handle gears down to 3:73s at the lowest. Your stock 3:55 carrier can handle 3:55 gears and down.

Do you have a part number or a link to the style Detroit that it is? May help us out with your options.

Depends on what type of locker. Is it the style locker that just replaces the spider gears IN the carrier? We need a little bit more info here LOL. Find it on Eatons website and post a link of the model locker here.

I dont have a model number on the locker because its still in its carrier but it does replace the spider gears http://i54.tinypic.com/2vuhffd.jpg can i take this one out of its carrier and put it in my existing 3.55 carrier

Who told you that was a detroit???? A Easton detroit locker is a full carrier replacement locker meaning the carrier itself is a locker even with their version of the auto locker called the "no spin" locker. That is not a detroit. That is an open carrier with some brand of auto or ''lunchbox" locker in it. Its either and Aussie, lockrite, or grizzly. Easton does not make them. So you should be able to ure existing carrier and gears as you seem to have done. No shimming required. You may need a new spring kit which will run you under 10 bucks depending on what make it is... By the looks of the pic it doesnt look like you out the springs and pins in yet, did you? And 100 bucks is still a great deal and you will be very happy with it...

Here is a pdf catalog of everything Easton makes. No lunchbox lockers....

I was told it was but im not really concerned about brand its brand new inside back to my original question can i take that gear that off of it now and put my 3.55 on it the gear on it now is a 4.56 and would like to out a 3.55 on it to make installation easier

[LIsurfcasters]

You will not be able to put the 3.55 gear on that carrier bc it's a different carrier. The break for a Dana 30 is
3.54 and down; 3.73 and up.
The 3.73 and up carrier has the mounting location for the ring gear in a different spot than the 3.54 and down. It puts the ring gear closer to the pinion to make up for the smaller pinion as the gear ratio increases.

Ok would i be able to put that locker in my 3.55 carrier then

Yeah if it's a lunchbox style locker then yes you should be able to put it in the carrier as it would replace the spider gears. I'm not sure what brand it is but if you check out Aussie or spartan they should have install instructions with pictures step by step.

YUP. Thats some brand of lunchbox locker. You can move it over to your carrier and it should be easy. My biggest concern is that if the seller didnt know it was NOT a Detroit then how does he know it will work in your truck. Just make sure it came out a D30 axle. High pinion or Low pinion does not matter. Also that its 27 spline. But like HULUL said, they are great setups and work great. As long as its for a D30 you will love it. But i would find out what brand and get a new spring kit for it. they do where out and its just a smart thing to do since you dont know its history. If he thought it was a Detroit then i would take all his info with a grain of salt.

[HuLuD44]

the spring kits might also fit between different makes as well if you cant figure out what make it is. Gonna be hard to tell since there are usually no markings on them. I know my aussie and lockrite seem by eye to be about the same size but Id look into it before buying anything. you can prob sell that ring gear and carrier for $40 -50 to compensate the locker expense since you cant use it anyway. As long as its a D30 it will fit in ure carrier regardless of the size break as said above. Super simple to install. Just knock out the carrier bolt pin crush sleeve and remove the pin. Remove locker and put it in the other carrier. It will take a little playing around to get it seated right cause they are a very tight fit. also the springs and pins are a PITA. Once the locker is inside onc at a time put the spring in then seat the pin in spring and push it all into the slot.
