Correcting an imbalance in a rotating shaft

A method of balancing a shaft, comprising:

• providing a joint assembly having a first joint member drivingly connected to a second joint member by one or more torque transmission elements, wherein a first shaft is drivingly connected to at least a portion of said first joint member, wherein at least a portion of a second shaft is drivingly connected to at least a portion of a second end portion of said second joint member, and wherein at least a portion of a boot can is attached to at least a portion of a first end portion of said second joint member, wherein a first end portion of said boot can further includes a substantially hook-shaped portion, and wherein said one or more retention members have a shape that is complementary to said substantially hook-shaped portion of said boot can;
• securing said joint assembly within a balancing machine;
• rotating said joint assembly within said balancing machine;
• identifying an imbalance within said first shaft and/or said second shaft;
• determining one or more balancing element locations and one or more balancing element masses needed to cancel out, minimize and/or eliminate said imbalance identified within said first shaft and/or said second shaft;
• and
• attaching said hook-shaped portion of said one or more balancing elements having said one or more balancing element masses determined to said substantially hook-shaped portion of said boot can in said one or more balancing element locations determined on said boot can.
