TSB: The purpose of this bulletin is to notify technicians of the best practices to help reduce brake vibration conditions for our customers. The condition can occur at any time if improper torque is applied to lug nuts. Over time, even one lug nut over- or under-torqued can cause a vibration condition. When lug nuts are over-torqued, this causes the rotor to have a runout condition, which can lead to brake vibration conditions.
