Alright, long time listener, first time caller.
I bought this truck coming up on a year ago, and haven't gotten to drive it much, I keep finding myself fixing one problem, and then the next undriveable problem pops up.
Current issue, my rear driveshaft keeps immediately popping out of carrier bearings. After the first time, I was able to limp it back home through all the terrible thunks and shaking, took the drive shaft to a shop who replaced the u joints, carrier bearing, cleaned and greased everything, checked to make sure it was in balance, and recommended replacing the yoke on my diff, because mine was pretty worn, presumably from losing at least one driveshaft at speed. Spent $350 or so, figuring that I'd fixed the problem and would finally be able to confidently drive this truck, affectionately known as "big *****". I made it about five miles before the brand new carrier bearing did the exact same thing as the last one.
The tow truck driver thought it was weird that the front half of my drive shaft seemed to be 'floating' - it was a slip yoke coming from the transfer case, through the carrier bearing, to another slip joint right behind the carrier. It wouldn't take much to push the drive shaft one way or another, forwards or backwards. He thought maybe it was the wrong transfer case for the truck? I have not been successful at shifting the transfer case or locking the hubs into 4x4 yet, so it's making me wonder if he was right.
The previous owner, in the post on marketplace, mentioned that when he was driving home after buying this truck, the driveshaft dropped out, causing him to have to buy a new one and get the truck towed. He also stated that the C6 had been freshly rebuilt, which it visibly looks to be.
I know I need to investigate the transfer case more, since it almost seems like it's trying to push the driveshaft out the back, but I wanted to make a post and see if this is something that anyone has experience with. I guess I should also check the transmission mounts to make sure that's not moving around in ways it shouldn't be.
Is it normal to have two slip yokes on the same driveshaft?
Pic attached of potentially the fastest ruined carrier bearing in US history.
