Goshen IN 46528.

Gently used Yukon 4340 front shafts for 03-06 Rubicon Dana 44. Good shape, U joints are good, no twists, ready to wheel.

the long side has some superficial wear due to a (Im guessing) a pebble or torn/damaged tube seal.

I got these in on trade and just need the money for them.

Nevertheless, $300 obo. I found these via quadratec for like $850 or something stupid.

No shipping, no trades.

Probably Spicers. I just picked up a Jeep with a D44 in the front that might be a Rubicon axle but it doesn't have an electric locker. It has an ARB. So I don't know if these would fit. Also since those are actually D30 shafts, I don't know how much better they are.

Not doubting you but how do you know they are Yukons?

Your d44 has d30 shafts? I know I’m preaching to the choir but D30 shafts are 27 spline and D44 are 30 spline. These are 30 spline.

They were in a Yukon box, and I had zero reason to doubt the guy. He got a deal on RCV’s and upgraded. These say 4340 on the stubs as well as the inners.

Oh, yes, the stubs are the same spline count and use the same 1330 5-760X U Joint.

Specifications:

Dana 44 - Rubicon Front
Inner Axle Spline Count - 30 Spline
U-Joint size - Choice of Spicer 5-760x or Yukon Super Joint
Sold as a set
Offroad Tough Chromoly Axles: Forged from 4340 Alloy Steel which is heat treated for superior strength & extreme durability. 4340 is a nickel-chromium-molybdenum alloy steel which touts high strength, fatigue resistance, and corrosion resistance. The yokes have added additional material for even more strength. Made with premium rolled splines, which gives a 30% increase in strength over original style cut splines.

Yukon Super U-Joint (Option): These super strong u-joints eliminate needle bearings resulting in a larger trunnion. Producing a stout u-joint that uses ultra high grade anti-seize for lubrication. These Super Joints are NOT recommended for the daily driver. They are designed for abuse, hardcore wheeling applications, and competitions in your Jeep. This package does include anti-seize and grease gun.

Dana Spicer 5-760x U-Joint (Option): These u-joints have stood the test of time and are extremely durable. They are recommended for the daily driver and for light to moderate offroad use.

The weak link is the joint. Super joints have a lube port in each cap so I suspect they are Spicers.

Fair enough.

Ok, so at the ridiculous cost savings that is going here over new - would you simply feel comfortable buying said Super Joints?

Oh, and Im kinda slow - in regards to your comment above. Factory 03-06 Rubicons do not have electric lockers - thats 07+. 03-06 Rubicons also do not have ARB's, they do have a proprietary air locker however. These air lockers take 5psi to lock, whereas the ARb takes between 85-105psi to lock. Front axles have a open/spool, whereas the rears have a limited/spool.

I could be reading too much into what you're saying, obviously someone could have swapped in an ARB, however it seems unlikely due to the factory front lockers being pretty strong.

All I currently know is that it is an ARB (switches and air compressor) and a D44 dif cover installed into a 99 TJ. Beyond that, I need to do research to know if they would fit.

Looks like a moog joint Spicers 5-760x are not greasable
And looks like it’s a moog super joint possibly by the numbers on joint
