Tech notes: Performed short test--found fault for LR AXLE and BEARING
Alright, either the tech is stupid, lazy, or does not know how to write a story.
There is no fault that a wheel bearing or axle will set in the computer. NONE! They are mechanical components. There is a wheel speed sensor that reads vehicle speed, but that's it. I still am of the opinion that they are simply incopetent, and telling you a story.
Here is a diagram of the rear wheel bearing. No electronic components.
