Subject: EXTERIOR MIRROR VIBRATION/SHAKE


Model and Year: 1988-91 C/K TRUCKS


Some 1988 - 91 C/K vehicles may experience an outside rear view mirror shake after the mounting of a bug/air deflector.

Studies have been performed to substantiate that this condition (outside rear view mirror shakes when SPO or aftermarket bug/air deflector is added) does occur at speeds above 50 mph.

To correct this condition, remove the SPO or aftermarket bug/air deflector.
