This is one of those videos where you see the problem and just are dying to know what happened. You’re about to watch an under-truck view of a transfer case replacement in a full size Dodge truck. That sounds pretty boring until you see the fact that the one in the truck has exploded, blowing the case apart and sending the massive chain inside swinging around to destroy anything and everything it could come into contact with. From the description, it nearly beat its way through the floor.
The added complexity of this job is not just the fact that all the junk is blown up and broken but the fact that the chain also wiped out the wiring harness headed to the back of the truck so after the nut and bolt work is done, the electrical fun can begin.
We know that one of the reasons most four wheel drive trucks are limited to like 96 mph from the factory is because of the transfer cases that they use and the fact that high speeds can cause major league failures. We’re not saying that this guy was roaring down the road at 120 when things got unhappy but good gravy, this is a nasty one!
