Have you busted a front diff? Poll

[ats4x4dotcom]

Front diff is a reasonably common problem, and can easily be made as strong as it can be, with the same mods we do to the rear.

All the broken ones we have fixed, havent had one back broken after we have fixed it.

And a live axle cw and p fits into the IFS diff, so maybe a good time to chnage ratio's as well, if running bigger tyres.

i hate these threads

it seems like most of these happen in snow and with wheel lifts and hard shocking hits, eh? has anyone broken one in mud or lack of traction on dirt?

by the way i have driven for the last 4 winters, im super surprised my diff hasnt exploded yet. Maybe i will get to do it this winter!

Is there a step-by-step ARB front locker install thread? I tried the search and couldn't find one. I'm thinking this will be my next mod, anyone know who has the best price on the ARB?

Unless you have experience setting up a third member you'll need a good diff set-up guy. However removing the front diff and reinstalling post ARB is straightforward. I followed the FSM. For specialty tools you'll need a steering knuckle puller, brass hammer and/or brass drift, 54mm socket and CV boot kit and clamp pliers if you'll be rebuilding the CV's.

and a lathe, and dial indicator, so you can check the arb carrier for runout, and machine if required before fitting crownwheel.

You will also need a lathe, and some material to make the solid pinion spacer, to make the diff as strong as it can be with an ARB locker, and we ALWAYS replace the bearings, as you cant tell if you damaged them at all getting them off.

X2 on the FSM, it made the job pretty easy.
BTW 54mm = 2-1/8" sometimes it's easier to find a socket this size in SAE units.

Good point...I, like you, bought the 3/4 drive Craftsman 2-1/8" socket.

The bad news is my 40 uses the same size hub nut.

Rather than buy two 3/4" breaker bars I'm going to get a 1/2" X 3/4" adapter extension and a second socket to carry in the 100.

Let me know where you find the 1/2"x3/4" adapter because I couldn't locate one when I searched before...

HF is good for stuff like that...

Thank you Thank you O king of the surf !! I asked about this very item at the Sears store and he told me they did not make or offer such an item. I should know better .

 

[hoser]

Haha, not really a title I desire so if you guys keep it up, I'm going to stop helpin' y'all out.

Wow, how did I miss this thread? I must have been avoiding the subliminal message. I just voted, but wanted that "moderate ofroading" choice also.


Have a nice day, I'm going to the garage now to check my diff fluid.



I just remembered that I still have the pieces. Maybe I can smash them into the front of a "pumpkin" this year on the porch.

Sorry guys, I'm leaving for more coffee now....

I can find one in my tool box.
It's in the 2-1/8" socket.

Like hoser said Sears, it may be a catalog order thing. But IIRC I got mine from the store to set the torque on the 40 hub nuts. Both of my torque wrenches are 1/2" drive.

 

[hoser]

Oh, and thanks for bringing this up. I need to buy this big az socket as it's time for a front bearing repack/service.

Truth be known most guys use a screwdriver and a hammer to spin the hub nut off in the field. Whatever works to get you home.

But it is essential to have one in your tool box at home to set the hub nut torque.

Do you see broken front diffs more commonly with the two pinion vs the four pinion models??

Earlier models, though they have normally been wheeled harder, with larger tyres, and getting older.
