Summary:

Shortly after a normal touchdown, the right outer (No 4) mainwheel separated from its axle and was seen, by the pilots, to pass down the right side of the aircraft. The aircraft vacated the runway and was safely brought to a halt on the taxiway. The wheel separated as a result of a failure of the inboard wheel bearing which led to the failure of the outer bearing. The exact cause of the initial failure to the inboard bearing could not be determined.
