:thinking:Rubicon vs non Rubicon axle confusion :thinking:
Hey there, I’m going to try to clear up the confusion when dealing with a Jeep TJ and JK Dana 44 axle that too often results in wrong part syndrome. The issue that causes all the confusion and all the incorrectly ordered parts is the widely unknown differences between the TruLok differential found in the Rubicon, and the standard differential. Until recently the TruLok differential was exclusively used in the Jeep Rubicon models. Starting in 2016 The TruLok was offered as an option in some non-Rubicon models, this will likely further confuse things as the TruLok has always been referred to as Rubicon or non-Rubicon in the aftermarket world for with or without. While the 35 spline axle upgrade lockers for the JK Rubicon/TruLok is available thru a few companies OX, ARB, and Auburn Gear. Currently the only drop in replacement lockers for the stock front 30 spline and rear 32 spline JK Rubicon/TruLok differentials are available thru OX.

TJ Rubicon vs Non Rubicon​

Let’s start with the Jeep TJ, this one is pretty simple. The only real difference here is the case break and ring gear bolt diameter. The TJ Rubicon Carrier has no case brake and uses the same carrier for all gear ratios and a thick ring gear to make up for it in the higher numeric ratios. Just remember to use the 3.73 and numerically lower gear ratio carrier, and a thick gear for any ratio numerically higher than 3.73 when replacing parts on the TJ Rubicon.

JK Rubicon vs Non Rubicon
OK, here is where the confusion kicks in, the differences between TruLok and non-TruLok or more commonly known as Rubicon and non-Rubicon are: The carrier bearings, the cross pin offset, the axle shaft spline count of 32 (for rear only), and the axle lengths. The confusion becomes further multiplied when we start with the aftermarket upgrades like larger axle shafts and lockers. Thank goodness the JK has no case break, one carrier case for all gear ratios. Let’s take a closer look and break down the differences for the JK categorically by carriers, ring and pinions, housings and axle shafts.

Carriers
The TruLok and Non-TruLok differential carrier bearings are different in outer diameter, inner diameter and thickness which also equates to a different housing. The TruLok carrier not only has different bearing journal diameters the bearing seats are moved out about .200” on each side to make up for the thinner bearing sets. Next, is the cross pin location, the TruLok cross pin was moved about ¾” actually .770” towards the ring gear. This was necessary to fit the TruLok locking mechanism. As a result of the cross pin relocation the axle lengths changed.

Housings
The housings between Rubicon/TruLok and Non are dimensionally the same with exception to the carrier bearing diameters. The Rubicon/TruLok diameter is 84mm (3.307”) and Non or the standard Dana 44 measuring out at 3.265” there are currently no conversion bearings available. There are many aftermarket housings available offering both configurations, make sure to order correctly.

Axle Shafts
When working with a Rubicon/TruLok housing and carrier the cross pin offset needs to be taken into account as it will affect shaft length. Lets look at the front first. Using the stock 30 spline is pretty straight forward. The stock length inner shafts for a Rubicon/TruLok housing should be used (LH 19.72”RH 33.64”). There are many companies offering the correct length chromoly upgrades which are typically 40% to 50% stronger than stock.
If upgrading to 35 spline the cross pin offset goes back to the original location, and the axle shafts lengths change to (LH 19.02” RH 34.35”). These shaft are also available from a few sources and are usually chromoly almost overkill for a front Dana 44 application.
Moving on to the rear (32 spline), again like the front, if you're using the stock spline count, stock length shafts required (LH 31.1” RH 32.5”) if upgrading to 35 spline it goes back to equal length stock JK non Rubicon/TruLok length of 31.80” which are available in many brands most all in chromoly.

Thanks for the write up. I just picked up a set of Rubicon front and rears to swap into my JKU. I will be tearing them down this weekend and replacing all the bearings and seals, adding gussets, and replacing LCA front brackets, and front and rear track bar brackets.

Ummm did they become a vendor here? Or did they just join and not read the rules about advertising? Hopefully not the latter as I really do like their products and would be very disappointed if they start acting like a few of the companies that have been on here

I hope so too. I have stated in other posts that I really do like their lockers after having them in one of my cj7s. So hopefully they will become vendors here and not do like a few other companies have. I plan on going with their lockers wheen I eventually do am axle swap, but if they try and pimp here like some others have then I will just go with arb.

I hope they choose to stick around in a proper way. I love seeing new vendors that want to participate here, but it really pisses me off if they truly and intentionally disobey the rules hoping to advertise for free.
