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 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 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 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.
