EXTERIOR MIRROR VIBRATION OR SHAKE/REMOVAL OF AFTERMARKET BUG/AIR DEFLECTOR
MODELS:
1988-91 C/K VEHICLES
Some 1988-91 C/K trucks 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.
