We here at Stage 3 are pretty hard on our trucks, but despite the amount of wheeling we do, we've only had a few issues on company time (though a few more in our own personal time). However, on our 2021 Sasquatch Bronco Build's first real outing into the dirt, we managed to break something that caused all sorts of havoc with our Bronco's ABS, traction control, drive modes, AdvanceTrac, and cruise control. What the hell happened to cause issues across all these different systems? Well, welcome to the world of integrated systems that are all tied into a single sensor and how the failure of a single bearing can cause so many systemic problems. The root cause of all of our issues was a failed rear axle bearing, but that failure which usually wouldn't be all that annoying caused a lot of problems for our Bronco, and the reason why is fascinating and shows the pitfalls of adding technological systems to trucks all tied into a single point of failure.
