Abstract

A balance correction device is supported within a hollow article, such as a driveshaft assembly for a vehicular drive train system, to balance the article for rotation. The balance correction device includes a first disc having a first slot provided therein and a second disc having a second slot provided therein. Portions of the first and second slots are axially aligned with one another. An object, such as a ball, is received within the axially aligned portions of the first and second slots. The first and second discs can be positioned relative to one another to position the object relative to the unbalanced article to balance the unbalanced article for rotation.
