that sounds dead on. How much additional damage am I doing by running less than 30mph with the 4wd engaged here in the snow until I get it fixed?
I would fix it ASAP and only drive it as far as it takes to get to a shop. I saw mine in the condition you see in the video but decided to try to get on to the next city about 65 miles down the road. By the time I got there, the tapping sound when I started out was a LOUD BANGING sound. (think bowling ball in a dryer)
I could somewhat control the banging by adjusting the throttle to smooth it out but it was not a good thing. I was able to limp it to a motel and call around to find a shop who could work on it the next morning. I stopped at a (semi) truck parts shop along the way to ask if they could recommend shops very close by and they suggested the one I ended up using. I limped it to the shop in the morning instead of messing with roadside, since it was only a 2.7 miles on a 2 lane city street with a 30mph limit.
The shop said they would have to see if I might need a new driveshaft, if it spun the bearing. But thankfully it didn't damage the driveshaft or anything else, so it just needed the carrier bearing.
It requires a shop press and other special equipment, so it's probably best to have a shop do it, unless you are comfortable getting that deep into repairs. I was out on the road and had so such equipment. It cost me about $300, as I recall. They had it done within about 3 hours.
