Squeak or Creak Noise When Driving Over Bumps on Lincoln Zephyr

A squeak or creak noise may be noted when driving over bumps. Our technicians tell us of two possible causes. The lower control arm may have faulty welds or the strut jounce bumper could be rubbing on a dry strut plate. There is a factory repair kit for the lower control arms. If the noise is coming from the strut it may require dis-assembly to lubricate the jounce bumper.
