Fixing Lincoln Underbody Rattle
Some 2017 Lincoln Continental vehicles built on or before Oct. 19, 2016 may exhibit a rattle noise from the underbody.
This may be due to the movement of loose underbody shield fasteners attached to the underbody shields.
With the vehicle on a lift, inspect for loose or missing fasteners. Replace with P/N H2GZ-19E525-A (kit).
