Ultimately the take-off and landing loads are transferred to the Main Landing Gear Wheel Bearings. These parts bear tremendous loads such that their life is limited. In ideal cases the failure does not damage the wheel hub and replacement is a routine operation.
But in the most extreme cases the bearing can fail in a destructive manner leading to damage of the wheel hub. This damage is the the result of the steel bearing digging into the aluminum wheel hub. When this occurs a new bearing cannot be inserted and the wheel is often condemned.
The solution is the subject repair.
