Abstract
Locking nut assembly for use on a shaft such as the bearing hub of four wheel drive vehicle. The shaft is externally threaded and has a longitudinally extending slot, with a nut threadedly mounted on the shaft. A first lock part is mounted on the shaft beneath the nut with a tab which extends into the slot to prevent rotation of the first lock part relative to the shaft. A second lock part is mounted over the nut with a noncircular opening in which the nut is received so that the nut cannot rotate relative to the second lock part. The two lock parts are locked together so that the second lock part cannot rotate relative to the first. In the disclosed embodiments, the two lock parts are locked together by a lug which extends from one part to the other.
