Symptom/Vehicle Issue: Hood Flutter Movement Or Bounce While Driving
Customer Complaint/Technician Observation: On a test drive the hood may appear
to flutter or shake. Condition may happen more in high speed or high wind situations.
Other possible complaints may include hood wobble, high hood closing efforts, hood to
fender fit / flushness. If any of these conditions are observed, refer to the below
procedures for hood adjustments
Discussion:

paper from between the bumper and hood surface. If paper slides from between any
of the four up/down bumpers, raise that bumper by turning it counterclockwise until
