Your driving conditions will cause grit, dust, fluid and grime to take their toll on the bushings over time. To keep the joints properly functioning, you will need to rebuild them occasionally to restore them to their original top working condition. This FlexArm joint rebuild kit from TeraFlex comes with all replacement components for your task and includes two urethane bushings, a snap ring, a large retainer washer and a chrome-plated misalignment ball.
