Driving without ring and pinion

Well, broke my ring gear in my front D30, luckily I can still roll forward, but not back. Pulled into my garage and opened up the diff:

Since I cannot back out of the garage, and I am not equipped to fix the broken gears, I could pull them out and reinsert the inner axles so I can drive it to a shop. Is this possible?

Pull the axle shafts. Remove the carrier. Remove the ring gear from the carrier and reinstall the carrier. You can than reinstall the shafts. Be sure to remove the front driveshaft until your gears are replaced. Be sure to put gear lube back in the axle. The spider gears will not be happy if you don't.

Alternatively you could pull the shafts and re install with just the stub shafts, but just pulling the rear gear would probably be faster than dealing with the u joints.

Cool! I wasn't sure I could run inner axles without the carrier. This might be necessary out on the trail, though I got lucky and was able to drive home.

Just to be clear, you cannot run the inner axle shafts without the carrier (the part that the ring gear is attached to)

If you have a floor jack on wheels, just jack up the front then back the Jeep out. Spin it around with the jack and drive it to the shop.

Wow. I've never tried to move the vehicle with the jack. I was thinking of a floor jack under each front tire, but then I would need... Another floor jack. Ok better just tear into it. If it has more internal damage I may replace the whole thing anyway.

Hey just for our information what brand ring and pinion are you running and how did you break it? If you're not heard correctly maybe nows the time.

take the ring gear off the carrier.put the carrier back in.put axles back in. add oil for the bearings and you can drive it that way. my friend drove home from mexico like that but his was a rear axle broke. since the ring gear will be gone you just need oil for the bearings. any ol 10w40 or whatever you have will lube the bearings fine.

Not sure the brand (Yukon?) but it was installed by a professional and he does not use junk. I broke it no doubt by pulling backwards on a snatch strap repeatedly to pull a buddy out of a river. The wrangler is too light and dances around on the end of a snatch strap. The gears may have gotten chewed by that because I drove all the way back to the trailhead before discovering I could not back up. When I opened up the diff there was no large chunks, just a silvery fluid, so it looks like it just chewed itself up. Someone suggested the carrier might have moved around and misaligned.

I carry a pair of stubs that have the yoke busted or stretched out to the point the caps slip in. yank both shafts and install the spare stubs to hold the unit bearings together. theres no need to even pull the cover or drive shaft. no spares? so what, itll cost you a couple axle joints if you mess them up getting the stubs off.

I have a spare set of shafts that I kept from my LP when I swapped them in. Essentially when I break one that is what I am going to do (if I don't get chromo before that)

Follow up: Pulled the axles, got the carrier out and removed the ring gear, put it all back together and I have a rear wheel drive Jeep. Yes, you can drive without a ring gear just fine. Shop quoted me $1400 to rebuild the whole thing, looking for other options.
