Im planning on doing the same thing but why do you need a new carrier in a d30 and not an 8.25? And what kind of new carrier do you need, is it a specialty part or just another of the same?

 

I see. I will try to look for a set of these axles next time I am at the junk yard.

 

The D30 has different carrier for the different gear ratios and 4.10s will not work on a 3.55 carrier. If you have a D35 or a D44 rear you would need a different carrier for them as well.Since those axles are made by Dana/Spicer, that is how they have designed their setup.

The 8.25 is designed and built by Chrysler and it is just how they set theirs up. The only difference in the 8.25 carriers in between the 27 and 29 spline differentials. You can go from 3.07 on a 8.25 all the way to 4.88s with the same carrier.

 

i am running .55 gears and i cant wait to swap. i have been looking 4 stock jy axles but no luck yet. im thinkin bout having a local shop doing it 4 me. what do u think is a fair price for labor to intall gears? also as far as carriers if u put an arb in the front do u still need to swap carriers?

 

With the ARB, the locker replaces the carrier as an assembly.

I went to 4 Wheel Parts this week to pick up a set of leaf spring perches and got a quote for having gears installed while I was there. For them to supply all the parts to change to 4.56 gears(except carriers because I have factory 4.10 axles in the garage) and the labor was $1100. That is even with me taking in the axles off of the vehicle so they can work on them on a work bench and not under the vehicle. The labor cost may be different in your area.

 

i was quoted 500 per axle so 1000 for both plus a little extra for installing the arb. but i think im gunna have tem install the locker. i will be able to do the compressor and run all the electrical myself. i just thought 1g seemed high for labor. when gears are concerned i would rather pay someone to do it right instead of tryin myself and screwing it up. sorry for the thread jack

 

ok, so can someone give me a complete list of parts i will need to do the swap. i plan on using stock axles. i need the list like carriers, ring & pinion, etc. and im asuming i can get it all from ringpinion.com right? thanks again guys. oh another thing is this type of swap you can do over a weekend? i have a lift in my garage andy a buddy who has beeter know how than me when it comes to gears.

 

Swapping gears is a time consuming process because of all the setup procedures. You may have to disassemble and reassemble the whole thing 3 or 4 times to get everything right. But with the right tools and knowledge, yes it can be done in a weekend.

Parts needed:
D30 - new ring and pinion gear set, new carrier for 3.90 and up gearing, new master install kit (bearings, seals, shims).

8.25 - new ring and pinion gear set, new master install kit.

Additional supplies:
several cans of brake cleaner
new gear oil
sealer for the diff cover

 

yea my buddy said its time consuming. he told me something about bearing preload settings and gear lash measurments and stuff. it sounded chinese to me when he was explaining it to me.

 

yeah... i know how to do it but i dont have the patience to do it or the specialty tools to do it. as much as i dont want to shell out the money to pay someone to do it i think im gunna bite the bullet and let someone else deal with it

 

okay im new to this forum and what not but i want to run 33's on my stock 2001 4.0 cherokee. so can i just find a 4 cylinder cherokee at the junkyard and pull the axles out of it and put them on mine and im done and i have 4.10 gears? and even though theyre not 4.56 they would still help?

 

good luck running 33s on a stock cherokee.

 

ha ha x2

 

Ohhh I meant stock as far as axels. It has a 3 inch lift, I'm gonna cut my fenders and add some sort of a body lift until I can afford better. But you guys didn't answer my question about the axels haha

 

i run 33's with 4.10's on a 30/8.25 setup ddoes great for me
