➤ WHEEL BEARING EXPLAINED – SUPPORTING LOAD AND ENABLING ROTATION A wheel bearing is a precision-engineered rolling element assembly that allows a vehicle’s wheel and hub to rotate smoothly with minimal friction while supporting both vertical and lateral loads. It plays a critical role in vehicle safety, handling stability, ride comfort, and drivetrain efficiency. --- ➤ PURPOSE OF THE WHEEL BEARING Wheel bearings serve multiple critical functions: • Support the vehicle’s weight (radial load) • H

AXIAL LOAD INJURIES: @the_resuscitationist There is a classic Cervical Spine injury associated with this mechanism of injury. Can also be seen with roll-overs where a passenger head/neck axial load against the roof injuries among others. C-1 BURST aka "Jefferson's Fracture" caused by axial load from occipital condyles to lateral masses. 1. Fracture of the anterior posterior arches of C1 (Atlas) 2. Classically linked w/ other Cspine fractures 3. May also see vertebral artery dissections. Jefferso
