I'm preparing to run the Rubicon this late summer. I'm thinking through and trying to prepare for the most common breaks and trail repairs. I am on stock shafts. The jeep is on 37s with a 3.5" metal cloak lift. Fully belly skids. I wheel with a light foot. I'll be going with a few other similarly equiped Gladiators.

Correct me if I am wrong:
1) If I break a front U-joint or even the axle shaft, and I am unable to repair or replace it on the trail, as long as I keep the stub shaft in the hub, I can remove the rest of the axle shaft, correct? Assuming something more catastrophic didn't damage the housing or bearings and I stuff a rag in the axle tube to mitigate fluid loss and trail debris/dirt. I did a little search and someone mentioned you don't even need to run the stub shaft?

To take this a little further... If I have one of the front shafts removed, unlocked (front) 4x4 is not going to any good for traction, but do you guys see any obvious danger in turning the front locker on when needed?

Any other advice for spares would be helpful. I plan to bring u-joints and the associated tools. I have a spare front driveshaft to bring (although I don't think it's very likely to use it). Duct tape, zip ties, ratchet straps. I don't have spare axle shafts. I want to upgrade my front axle shafts someday, but I don't think that's going to be this year. I'll be bringing some fluids as well. I have been wheeling for about 15 years, but the worst damage I have earned is a slightly bent tie rod and dinged up rocker panel on my old TJ. I may be lucky and I am concerned I am getting complacent with being "prepared".

I'll let someone who's thrown one comment on the axle shaft field repair.

If they're all Rubi JTs, may be worth spreading the spares since all your front ends are the same. Your DS may work for everyone, one set of shafts may work for everyone too.

We have the same thoughts. One gladiator is a Rubi (running stock shafts), the other is a well built Willys (narrow front D44, though). The Willys has spare front shafts because he's upgraded to RCVs, but they won't work on the Rubicons (unless we just need the stub shaft).

Be careful using the front diff locked with only one axle shaft. It's fine as a "helper", but 100% of the torque sent to the front diff will be applied to that one axle. So, easy on the skinny pedal. Climbing conditions where the rear axle may completely unload could put a lot of stress on that axle if that wheel has traction.

Very good point. First course of action would be to winch or get pulled through anything that's giving us a hard time (in 2wd).
