If no tags are there you will have to pull the cover and count teeth on the ring and pinion, I think. Can't figure another way except to rotate the pinion and see the amount of turns required to turn the tire one revolution. Then byou will have to approximate the ratio from the possible choices DC had for that particular year. Good Luck!

To find the gear ratio request a build sheet from Jeep, takes a couple of days. You will need the VIN from each Jeep.

Running a full-circle clip on an OEM shaft requires some clearancing of the shaft ears to allow room for the clip. This requires actual work, which I am generally adverse to, so we used to weld the caps to the shaft. Which brings us to yet another point

Are you talking about the needle bearing cap clips? Otherwise, I'm lost. Help a youngin out

Thanks, Sean

You will need the carrier as well.

 

[emr1101]

huh? no find a complete dana 30 with 4.10s already geared at the factory, i will not need a carrier its already in there

Yea, and?

That works too.

 

[emr1101]

haha then why did you tell me i need a carrier, from the get go i was planning on a 4.10 geared stocker

 

[CanMan]

Because you never specified you were swapping the whole front axle.

haha, why did you ask a stupid question in the first place?

Going to upgrade your rear to a 4.10 axle too? Or are you going to ask the same question in a different thread?

I Just swapped my vacumme disconect axle out for one that doesnt have the disconect. Did it really matter or did i do good???

 

[CanMan]

You got rid of the 2 piece shafts that come in the vacumm disco housing.

Did ya make sure the gears were the same?

 

[87xjstafford]

No, i completely swapped in a D30 that doesnt have any vacumme disco.

 

[CanMan]

Yes, that is what you said.

Make sure you have the same gear ratios front and rear before you use 4wd. If they are different, your T case will explode.

 

[87xjstafford]

Yeah I checked the tags on the diff.


The D30 without the disconect is sapoes to be stronger rite?

 

[ocean_jet]

The D30 HOUSING with the disconnect is supposedly stronger than the D30 housing without the disconnect, because the disconnect D30 has a cast passanger side UCA mount, that is stronger than the sheet metal UCA mount on the non-disconnect.

 

[87xjstafford]

Oh ok thank you.

It's easier to get bigger U-Joints with the Non-Disconnect axle. It also takes out the hassle of the disco portion of the axle. Those are the only upsides I'm aware of.

 

[87xjstafford]

Oh, cool.

You will need the carrier as well.

I know you need a new carrer when switching the ring and pinion to anything in the 4's, but i will not need a new one to change from my 3.07s to 3.54 correct?

Correct, you can use the same carrier.
