    Alright guys it's been a while for a burban update, just been daily driving it for a little over a year. Until... rear end carnage, I changed the fluid a year ago and even checked the tightness of the center pin bolt, put it all together and all was fine and dandy for that period.

    About a month ago I was making a turn, I decelerated and at about 25mph right when the trans downshifts to first, I get jerked forward pretty good for a split second and then she freed up, I hardly dropped speed. This all happens right before I make the turn, so it's free and I made the turn, but now I'm wondering what the hell just happened and seconds later going about 10-15 mph she locks up solid, right in the middle of a one lane road, granted it was late at night and the outskirts of town, but I was still stuck solid in the middle of a city street.

    So I got out and looked, nothing abnormal, so I get back in and put it in drive and I can still feel driveline movement in 2wd so I started gassin on it forward and reverse and she was just stalling on the converter or I wasn't giving it that much. I started to get frustrated so I rocked that bitch and she broke free the obstruction:rotflmao: but now... new problem I have no go lol, I leave it in drive and it's not moving and I get out to look and I look at the driveshaft and it's just spinning it's little heart out not doing jack shit:rotflmao: so I got back in, put her in neutral, shifted to 4wd and limped to the nearest approach, then came back that same night with a truck and trailer, so it didn't get towed or stolen, and I towed it back home to find this bundle of joy
    :Grenade:

    Side note- the pictures are exactly how I found everything when I opened it up, haven't found the center pin bolt yet but still have to go through my drain pan.

    More carnage.

    I will be rebuilding this axle as I can't afford to 3/4 ton swap it right now, as the 3/4 axles I have need to be rebuilt as well.

    Plan is same ratio 3.73's, since I have to replace the carrier anyways no sense in blowing money on an open diff so I'll be getting a Detroit truetrac, new ring and pinion kit, new bearings inner and outer, seals, all new brake components, then new axle mounted brake lines, and a nice paint job.

    But that will be awhile, so the burban is gonna be down for a while. Sad times lol

    Sucks man. Glad it didn’t lock up on the highway or something. That is some good carnage.

    Yes I definitely am thankful for that, it would have been a backroad at about 50 something as I usually stick to backroads from home to town, so it probably could have been even worse.

    On a brighter note I know I love some carnage so I've gotta share it with the group lol

    That's why I opted for the Detroit opposed to getting all new EVERYTHING for an open diff lol. At least it didn't blow a hole in the cover, it sure tried.

    Sweet fuck on a stick, that thing's toast. Never seen such a failure. I hate to say I chuckled a little when I saw the spiders just laying there all neatly at the bottom like that

    Trust me I chuckled pretty good when I opened the cover even after the bullshit I went through. Laughs are welcome lol. I believe the center pin dropped at the perfect time to hit against the top of the case, destroying the carrier and center pin then the carnage fell to the bottom all nice and neat. I got lucky all considering lol.

    That chunk of center pin in the spider gear was exactly how I pulled it out and that was my biggest how in the hell is that possible moment lol

    I haven't looked since I did a quick pull apart of it. I will look for the pin or what's left of it and will post an update.

    Holy cow!! That is definitely the worst (best?) gear bomb I have ever seen! Glad you are ok and weren't stranded somewhere.

    I was stranded for a little bit lol I was slightly panicking that it was locked up in the middle of the road. But I just got a little hillibilly with it lol.

    Personally I've never seen a better one haha I've seen stripped pinions, broken ring gear teeth, messed up spider gears, burned up rear ends but this thing straight GRENADED lol

    Also that whole rear end fiasco happened after midnight and the temps were -20's that night so I did NOT have fun loading and towing it home lol.

    Good 'ol 10-bolt under a heavy truck, lol.

    I've seen a few of them explode like that before. One of them even blew a hole clear through the cover and shrapnel took out the spare tire.
