Oh, yeah, it's not the end of the world. One case half is about $360, and the other was about the same at the dealership. You add a seal, and a chain, and an afternoon of wrenching, and you are not too bad off. If you are even slightly mechanically inclined, you can probably pull this off. Though, some of the bolts were a real bugger. I had to use a stubby ratchet, and break them free with a pipe against the handle, and a hammer. You have two, maybe three options. 1. buy a replacement. Going to be just under a grand. Check car-part.com 3. buy the case half and seal, and chain, and try it yourself. Buy some beverages and you may get some help from some others near you that aren't too afraid of it. 4. take it somewhere, like a trans shop, or a 4X4 shop, tell them what happened and ask if they are good enough at welding aluminum that they can put a patch on. It's not too far fetched, I have seen it done. There are worse things. One day I lost an axle seal, only I didn't know it. I also had been wheeling that day. In deep sandy muddy water. Guess what happened about half an hour later, on the freeway? My front axle locked up, exploded the gears, put a hole in the diff cover, and I came to a tire smoking screeching halt on the freeway. At least that didn't happen to you.
