Summary

This Preliminary information communicates that a driver may experience a vibration during moderate to wide open throttle acceleration. The dealer is advised that this condition is due to the extreme angles on the Z71/AT4 suspension causing a bind in the drive axles. The concern will be alleviated over time as the grease is distributed throughout the half shaft joints.
