Watch This Bronco Blow Out Its 4WD System Attempting to Speed Through a Mud Pit

https://www.msn.com/en-us/autos/enthusiasts/watch-this-bronco-blow-out-its-4wd-system-attempting-to-speed-through-a-mud-pit/ar-AASj8qX

We’ve determined time and time again just how capable the new Ford Bronco can be off-road. But like anything, there's a limit to how much abuse it can take. One owner learned this the hard way.

Eville Truck on YouTube, owner of a lightly modified 2021 four-door Bronco painted in Cyber Orange, decided to try to slam through a deep mud pit during a recent off-roading jaunt with a fellow Bronco. In the video above you can see the driver carry a whole bunch of speed going into the pit and entering at an awkward angle, slamming the truck into the ground and abruptly stopping, briefly lifting the rear into the air.

We hear the first bad drivetrain sound coming from the SUV, as if something in the driveline just snapped, while the truck tries to back up to get unstuck. The driver is still able to get the Bronco through the pit, but not without having to listen to a bunch of very expensive-sounding drivetrain knocks.

Afterward, the owner determines something in the 4WD system must’ve broken. As soon as it’s driven anywhere a terrible knocking sound comes from underneath the truck, and the front wheels don’t put down the torque they’re supposed to. Pop it into 2WD mode, and it works just fine. Whatever’s broken, we’re sure it won't be cheap to fix.

They don't make 'em like they use'ta.

My favorite fun is driving on Rt. 78 during snow or ice. Inevitably, a wanker, driving one of these will pass me. Minutes later, his car will be in the center median with the dude standing next to it, scratching his head.

I took notice of the new ones. they look nice, wouldn't mind having one to play with but alas the next vehicle really needs to be something that can pull a full stock trailer.

The 1970s Broncos had a Dana 20 transfer case, which sent power to a Dana 44 front axle and back to that which is next to impossible to break, a Ford 9 inch rear end. I'm certain even if the new Broncos have axles similar to the current 8.8 inch installed in recent F150s, these axles and the new transfer case (or transaxle) are not nearly as stout as the transfer case and axles installed in its predecessors.

There is no better way to trash your truck than entering a mud pit like that, the second best way is to enter the mudpit in the first place.
These new 4WDs rely on the computer to manage the 4WD and there are numerous safety features built in to the system to shut it down if things get too hot. Obviously that's not what happened here, but my point is the actual mechanical systems are not as robust the older systems. Personally I would rather buy an old Bronco than one of these new ones.
