Blown rear axle. What to do?

I have a stock YJ, 31" tires, the transfer and rear are totally gone. I got a new transfer case and now I am trying to figure out what to do with rear. Suggestions? I have done a TON of research. All fingers point to an 8.8 swap but I really don't need it. I won't be taking the thing mudding or anything. Is there any easy way to fix what I already have? I have never dealt with differentials.

XJ's and ZJ's are all over bone yards but if I were do go that far I may as well go with an 8.8.

If you just broke a shaft you could pull a set from a junkyard for like $50. How did it break?

Your profile is not complete, so I'll assume you have a D35. If correct, don't spend any money to fix that sucker. If you can get a D35 given to you and all you need is an axle shaft swap, or new Spider gears AND you can do the labor, go for it. However, if there is more to it, or if you have to pay labor, get yourself an 8.25 from another XJ. The 8.25 looks almost exactly like a D35. The specs on a 8.25 is not a lot better than a D35. However, in the real World, the 8.25 is a much better axle than the D35 and it is a direct bolt in replacement for a D35 in and XJ. 8.25 can be had for $100 - $200 and with 31 inch tires, it should be more than strong enough for you unless you really like that stupid pedal (gas pedal).

If you know your gear ratio and you can find the correct D35 ready to bolt in for free, go for it. Otherwise look for a 8.25 with correct gear ratio it will be worth the $100 to $200 extra. Whatever you do, don't start trying to repair a D35 as it will be like tossing money in a bottomless hole.

Cheapest and easiest would be to find a matching used rear diff (model and gear ratio) at a junkyard and swap it out. If your not going to wheel it at all don't bother upgrading. Because of Cash for Clunkers the yards around me are filled with XJs. If you've got a dana 35 with 3.55s (most likely) you could not walk through a junkyard near me without tripping over one.

I would just replace it with another D35. Otherwise, the 8.25 is a slightly better axle that can be installed easily. You'll just need to get the rear drive shaft that goes with the 8.25. Check out www.car-parts.com , it will tell you all the salvage yards near you that have it.

Well I considered replacing the spiders but the teeth on the ring and pinion are gone as well. I just moved out to CA and all my specialty tools ie a welder are back east. I am just using this jeep as my driver and am looking for the most simple fix. It's looking like finding another 35 with 3.07's is my best bet.

Anyone in NoCal have one?

At one point in time, I had a D35, complete from hub to hub, and in good working order with 3:07 gears in it. I thought I was never going to give that sucker away.... I mean literally give it away and yet no one wanted it.

**EDIT** Did an XJ have 3:07 gears, or are we talking about a different Jeep?

Finding a d35 with 3:07's shouldn't be that hard, but if you wanted to upgrade to better gears for the 31's you could easily find a set of axles from an auto XJ that will have 3:55 gears and will work great with your 31's and 5 speed. An 8.25 rear won't be any harder to bolt in than the d35, you just need the driveshaft from the donor jeep to go with it. I just looked at your profile and noticed the 2.5L. If this is true you have 4:10 gears and they will be even harder to find.

Okay..... let's clear the air. Do you have an XJ or are we talking about a YJ? Your profile and your comments DO NOT add up. What freak-n vehicle are we talking about?
