Thank you in advance for the help. Within the next month I will be swapping out my current 3.07 geared axles with a set of 4.10 geared axles (rear being a Dana 44). I will be using a friends lift to do the work with the assistance of him. He is mechanically inclined so I do not foresee any issues with the swap, but I want to ensure while we are in there that I replace what I should while having it apart. I have a 3.5" lift that I installed 10 years ago so it's time to replace the shocks, (I ordered new Rubicon Express shocks), new gaskets for the differentials, speedo gear for my tire/gear ratio size, fluids, etc. Brakes are all recently replaced. Is there anything major that I am missing/should do while I am in there? I also do not want to show up and be missing an obvious part and stall the swap. As stated before thanks for the help.

1997 Wrangler Sport w/ 4.0L and 5 Speed if that helps any.

PB blaster...start now. On all bolts/nuts that connect to the axle.

Are the axles out of a Rubicon? If so, you'll need to figure out driveshaft U-joint configuration. It's just easiest to swap in a new yoke for a 1310 joint.

Brakes....drum to disc?

Front track bar location? Do you have an adjustable track bar now?

Thanks for the quick response, in order of your questions:

-Out of a non Rubicon. The front is a Dana 30 and came from a Jeep that was regeared to 4:10''s so should be same as mine. Should I swap in a new yoke and if so, do you have a link to one?

-How expensive to change over to disks from Drum?

-I have an adjustable front trackbar on already that I installed last year so should be good in that department.

Thanks again.

As long as it came out of a non-Rubicon TJ, then you will be fine.

Not sure on cost as I did everything with parts I had. It's just a little time consuming is all.


Be sure to test everything at full bump and droop to make sure nothing makes contact. Set your bumpstops correctly to prevent this from happening. Make sure your driveshaft is the correct length.

The only problem I had when I swapped axles (also from 3.07 to 4.10's) is I snapped both front alignment cam bolts. I guess I didn't PB blast them as much as i should have. But no store had them and I had to order them from a federated auto store and it came in the next day. but other than that it was smooth. The difference from 3.07 to 4.10's with 33's is awesome too

I started PB Blasting everything about a month ago. Unfortunately the New England winters just reak havoc on our vehicles. Were you able to save and reuse your U-Joints?

New England? I'd have a spare set of bolts on hand:) You might try to see if you can loosen them now, if they don't budge, order a new set now so they are there when you do the install. I'm in dry Colorado and had to cut mine off with a sawzall.

As far as u-joints....what do you mean by re-use? If you are swapping your axle shafts over, you don't have to take apart the u-joints.
