The reason of this problem can be related to the damper pulley, which works as a damper to get rid of irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have the possibility that this phenomenon is annodine. As the serpentine belt of your Lincoln MKZ is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions.

I discover bearing noises on the serpentine belt of my Lincoln MKZ
Finally, if in your case you recognize a bearing belt noise on Lincoln MKZ, it is possible that it is related to a serpentine belt that is too tight . Indeed, it is possible that its size may be smaller than prescribed and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The risk in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to replace it if it is too short. If after checking all thoses alternatives, you still identify a belt noises, read our article about timing belt noises on Lincoln MKZ which could maybe help you.
